Color of the Year: Living Coral

hyssop flowers coral color

Each year, Pantone, which is the universal standard for color in printing and graphic design, selects a Pantone Color of the Year. The 2019 color is Living Coral. The color (Pantone 16-1546) is named for the coral that thrives beneath the surface of the sea and the warm pinkish-peach tone represents the natural warmth and comfort of a coral reef. One of the reasons for its selection is a trend noted by Pantone researchers of companies and designers using the color in branding efforts.

Living Coral in Nature

Often, garden writers plant sellers highlight bright purples, reds and yellows. They make for stunning photos or turning heads when driving by a landscape. But I’ve always loved this more subtle color. It’s not as common in native plants as are many other bloom colors. But the hint of pink, peach and oranges with golden tones beneath makes for some attractive combinations in the garden.

With undertones of peach, coral complements blues in the garden and the pinker tones look amazing with green. Softer hues of coral stand out with bright yellows. Aside from living coral in the sea, which most of us never will see in person, you can find  the color in natural items like peach blooms and peels or fresh salmon. It’s also a captivating color in the flowers of the plants below (click any thumbnail to scroll the gallery).

If your garden, houseplants or a favorite container lack coral color, think about adding some in its honorary year!

5 Tips for Choosing the Right Container for Your Plants

containers-austin-garden
Talavera, clay and metal pottery mix well on these garden shelves and walls.

If you’re like me, you often choose a container based on how much you like it or its color. Those are good reasons; after all, you want to enjoy your purchase when it’s in your home or on your patio. And the color might be important to curb appeal or your entryway statement. But it helps to keep in mind a few other tips for container choices based on:

small-tomato-plant-marigolds-large-container
This large container didn’t look sparse for long. The tomato grew and the marigolds spread.

Container Size

Some plants need a container large enough to support a plant’s growth. For example, even patio tomatoes need a pot about 12 inches in diameter.  The diameter is not always listed. A 10-inch container equates to about 3 gallons, and a 14-inch container to nearly 7 gallons, but it depends on the depth. As a general rule, go for about 5 gallons for container-grown tomatoes.

In 2004, standards were released to help ensure more consistent labeling from nurseries. For example, a 1-gallon potted plant is about 152 to 251 cubic inches, taking into account diameter and depth. Be sure to consider the mature size of plants when arranging containers.  For single plants, purchase a container at least a size larger than the one a plant comes in. There are exceptions, however.

burro-tail-succulent-containers
Many cacti and succulents need smaller pots to confine root growth; it’s fun to be creative with color and shape.

Some plants prefer crowded roots. Many succulents will fail to grow and flower if placed in a container that is too large. When in too large a pot, all the plant’s energy goes to the easiest activity – growing more roots. This means less energy can go into producing growth above the soil line. So, try not to go more than 10% larger than the size of the succulent. And keep in mind some succulents have tap roots and need enough depth for those roots to grow and seek water.

The same goes for a totally unrelated plant: the African violet. Violets do best with crowded roots and need good drainage, just like succulents. Place an African violet in a container smaller than the diameter of the leaves (those who grow the plants for shows generally choose containers one-third the diameter of the foliage). And repot plants like African violets every so often, gradually increasing container size as needed. Don’t take a violet (or succulent) in a 3-inch pot up to 10 inches in one repotting.

petunias-round-clay-pot
I love these shallow clay pots, but many plant roots need more depth.

Container Shape

Look at the container depth as well as its diameter. I love the look of shallow terracotta containers, but they only work with annuals and shallow-rooted plants. Those violets and many rosette-shaped succulents also can take shallower shapes. But your tomato needs good depth to form large, healthy roots. I’ve pulled up cherry tomato roots that were at least 15 inches long. And if your cactus has a tap root, make sure the pot’s height can allow for growth.

Container shape also affects plant placement and the overall appeal of the container. A tall container looks best with at least one tall plant element and maybe a trailing one.

glazed-container-table-containers-on-steps
Glazed pots can look colorful and elegant. and mix nicely with terracotta.

Container Material

Clay or terracotta pots are excellent for indoor or outdoor succulents. They dry out quickly because the sides are porous. These pots usually are your best bet for drought-tolerant plants, but not for vegetables or many ornamental flowers. And African violets in clay pots often dry out too quickly. Plastic and fabric pots are less expensive and lighter. The material’s weight is a consideration for any plant you know you might have to move to change sun or shade exposure, or bring indoors in winter.

metal-pitcher-succulent
It’s fun to create containers, but even succulent containers need some drainage.

Container Drainage

All containers need good drainage, even those you use for succulents. Few plants do well sitting in wet soil for long. If you repurpose a container, be sure to drill some holes in the bottom. And try not to let the container (especially a shallow one) sit in a full saucer if you use one to catch drainage. If your container appears to drain too quickly, change how you water – a little at a time repeated once or twice. Always add water to a container at a slow rate instead of a heavy pour. Drenching the container makes soil nutrients run right out with the water.

Lucinda Hutson’s Austin garden is one of the most colorful I’ve seen. I love the color of the paint with the three container colors.

Container Color

I have decided to go more colorful with container choices from now on. It’s tempting to “match” an entry or house color, or to have a container blend in on your patio. Sometimes, though, you can make a really bold statement by choosing a container that is bright, colorful (like Talavera pottery) or a nice contrast to plants inside and around it.

containers-patio-old-man-cactus-inside
The old man cactus (right) still thrives, although we have potted it up a few times.

Finally, if you find a container that will look perfect in a spot because of its color, shape or pattern, but maybe the wrong material or size for your plant, try slipping another pot inside it. I even did that once several years ago when I wanted to add an “old man cactus” (Cephalocereus senilis) to some annuals in a decorative entry-way container. I knew its watering needs were different, so I set the cactus pot into the soil of the larger pot and never really watered above it. The plant received plenty of moisture from the soil around its container. Then, I pulled the old man out in fall and we potted him inside for winter. He still is thriving, now in a terracotta pot with other cacti.

 

 

Chocolate Flower: You Can Grow That!

The daisy-like flowers of chocolate flower have a chocolate scent!

No, I’m not kidding. There is a flower that grows well in the Southwest that smells like chocolate. It’s like my two favorite things in one pretty package! Chocolate flower (Berlanderia lyrata) casts its rich scent throughout your garden. Be sure to plant it where you can bend over and take a whiff on those occasional days with no breeze. It’s an easy plant to grow and care for.

Native to Dry Areas

No wonder chocolate flower is easy to grow in New Mexico; it is native to dry plains and hills of New Mexico, Arizona, Colorado, Texas and Kansas. It grows best in elevations of 4,000 to 7,000 feet, so Berlanderia thrives in high deserts and intermountain areas like mine.

chocolate flower open and unopended blooms
Even the unopened buds on chocolate flower are pretty and delicate. Photo Courtesy of Plant Select.

Because it’s native, and probably because it looks and smells so great, chocolate flower attracts butterflies, bees and birds. And deer leave it alone! Need more reasons to grow chocolate flower? It reseeds naturally, but not aggressively, so one plant can turn into a few or more, depending on lots of conditions and where you plant the first one. Another great feature of this native is that it will reseed more naturally if planted near rocks or gravel mulch. The rocks “trap” the seeds when they blow in the wind.

Caring for Chocolate Flower

You can plant chocolate flower in nearly any type of soil, but it probably will do best if the soil drains well. Be sure to place it where it will receive plenty of sun – up to all day – and where its mature height (about a foot to 15 inches tall, and up to two feet wide) will work without overcrowding. Give it a little more water the first year, and then chocolate flower should grow and bloom with mostly rain only. Each spring, trim off dead flower stalks and some of the foliage if necessary to keep the plant base about three inches high.

unopened and spent blooms of chocolate flower plant
I first had trouble telling spent blooms from new ones for deadheading. Unopened blossoms have a pretty green and papery look. The circled one is a spent, dyring up bloom for deadheading or seed collection.

Chocolate flower is a perennial in zones 4 through 11, although ask for the variety best for your area. For example, High Country Gardens has introduced a new Mora County mix of B. lyrata that is particularly cold hardy (Mora County is a mountain and high plain area just northeast of Santa Fe). Deadheading, or removing spent blooms, keeps Berlanderia blooming.

I love the shape, color and scent of chocolate flower. When it and desert zinnia bloom at the same time, it’s a color explosion.

Enjoy Growing Chocolate Flower

Chocolate flower is in the daisy family, a relative of the sunflower and others, so it makes a nice cutting flower as part of an arrangement. You can bring that soft chocolate scent inside! I love the color of the flower buds – they look like a sage green paper flower. Its growth habit is bright and colorful but just wild enough to fit in a natural looking, xeric landscape. Leave some of the drying flower heads on your chocolate flower at the end of the season if you want it to reseed in your garden. Then watch in spring. If conditions are right, you might see a few new crowns of chocolate flower with the distinctive leaf pattern.

chocolate flower and blanketflower in rock garden
See how this chocolate flower grows up against the rocks. You will learn to recognize the leaf shape.

It’s a good thing chocolate flower can spread, because you can’t move it. The plant has a tap root (which helps its drought tolerance) that doesn’t survive division or transplanting. Otherwise, chocolate flower is a perfect, sunny perennial for a xeric garden.

5-Plus Secrets for Starting Seeds

It’s spring and time to think about growing food and flowers this summer. Save money when you start some seeds inside. You can find plenty of tips online for light, soil and water requirements, but I wanted to mention a few other hard-earned “secrets” from my experience and talking to others.

garden-vegetables-flowers

In general, start seeds about six weeks before your planting time for the variety. And be sure to pot up (move the smaller seedling to a larger pot) once while seedlings are inside. Here are 5 other tips:

basil-tomato-seedlings-label
It’s fun to start seeds inside, but only start plants that transplant well.

1. Before starting vegetable or herb seeds, be sure they transplant well.

If they do better with direct sowing (placing the seed right in the ground), wait not just past your last freeze but until air (and therefore, soil) temperatures have warmed. Cucumbers are a great example. I have planted them too soon and then had to plant again when the ground warmed because the first ones just didn’t take. Many annual flower seeds and some herbs do fine with direct sowing, which is easier than starting small plants inside.

carrots-in-ground
Carrots like cooler weather than some crops.

2. Not all vegetable seeds or seedlings go into the ground at the same time.

Lettuces, cilantro and carrots do better in spring or early fall than in summer heat. Tomatoes need moderate heat.  Planting and harvest times vary for edibles. This also goes with my next tip:

3. Look for information specific to your region.

Seed packets can help, but in New Mexico and other Southwest states, dates for planting vary widely. This goes for last or first frost dates and for peak heat. Low desert areas, in particular, have growing seasons markedly different from the rest of the country. Check with local nurseries, extension offices or master gardeners for help knowing when to plant.

These water towers warm the ground in my cooler region and help tomatoes adjust to the outdoors.

4. Thin seedlings.

This is the hardest lesson. But you should thin the seeds that sprout in your indoor start pots and those directly sown before they get too big and share roots. In the starter pot, it is best to take a small narrow pair of scissor or garden clippers and cut the spare seedlings off at the soil level. Pulling it up could damage all the seedlings in your pot. Thinning in the ground is a matter of preference for how your plants will look. But remember, crowded seedlings are not as healthy as single ones with plenty of room for their roots, and vegetable plants should not touch one another if possible. The leaves need sun and air flow.

green-beans-pole-fence
Green beans need room to spread, so remember their full size when sowing and thinning seeds.

5. Be sure to harden off seedlings.

This requires patience and some time. Your plants need to get used to their new home, just like flatlanders need to acclimate to high altitudes. Get your seed starts used to a breeze and the sun before placing them in the ground. Read more here about how to harden off your seed starts.

seed starts-in-tray-sun
This tray of seed starts got indoor sun, then gradual outdoor sun and breeze.

Plus:

Finally, start just enough for a spare or two in case a few seeds fail to take or the seedlings get off to a bad start. But don’t plant 10 tomato seeds indoors if you plan to grow only one or two plants, unless you have friends and family who would love to take your other healthy plants off your hands.

wildflowers-from-seed
These wildlfowers could have used more thinning, but I love the effect. You can’t plant tomatoes this close together, though.

Threadgrass: You Can Grow That

It sounds too good to be true: an ornamental grass that loves heat and looks beautiful all year gently swaying in the wind. But threadgrass (Nasella tennuissima) fits the bill — and is waterwise. This pretty low-water plant also is called silky thread grass or Mexican feather grass.

ladybug-on-threadgrass-flower-stalk
Can you spot the tightrope-walking lady bug on this threadgrass?

Texture and movement can add to a garden’s design nearly as much as shape and color. Threadgrass has a delicate, windswept form that serves as an attractive backdrop to low-growing flowering plants like sedums or verbena. In summer, the grass is a nice green with feathery ends. In winter, the airy flower heads take on a golden, wheat-like appearance. Threadgrass is deer resistant, has no known diseases or pests, and is a native plant that grows in zones 5 through 10.

Planting Threadgrass

Plant threadgrass in spring, summer or fall. Because it likes heat, you might be able to fill in a summer bare spot with threadgrass after weather is too hot for most garden plants. If you want a swaying meadow effect, you’ll need to plant a few, and then wait for them to reseed. If you want immediate effect, plant several. Just keep in mind the plant grows to about 12 inches wide.

threadgrass-two-plants-medium-sized
Young threadgrass plants that came up next to their mother plant.

Your threadgrass plants should reach about 18 to 24 inches high when fully grown, sometimes higher when blooming. Plant it in full sun and in most any kind of soil. When you first plant or transplant your threadgrass, give it a little extra water, especially in high heat.

bunches-ornamental-grass-shade
You also can bunch threadgrass for a meadow effect, like the grass in this Austin area garden.

Caring for Threadgrass

Once threadgrass is established, it should need nothing but rain water to grow and set seed. The plant is  a short-lived  perennial and should come back several years in a row, assuming typical low temperatures for the lower zones. It also reseeds (see below), creating new plants nearby. You can leave these to eventually replace the established ones, or dig them up and transplant them to another spot in your garden. They are easy to recognize.

threadgrass seedlings-dirt-near-large-plant
Tiny seedlings of threadgrass are easy to spot around other plants. Depending on where they show up and where you live, they are either free plants or invasive ones.

Each spring, as you begin pruning other plants in your garden, gently comb the grass blades with a fine rake and trim them for shape.

How perfect is the texture of the fine stems of threadgrass as part of this xeric plant grouping!

Caution for Some Gardeners

The fact that threadgrass replaces itself by sprouting tiny plants from seed is a bonus to me. We get just enough seedlings to move around our garden, without them being a problem. But in some areas, threadgrass can be invasive, reseeding in places where it interferes with other plants. In fact, the  plant is prohibited in California because it is so invasive there and can crowd out grasses native to coastal areas. It also can crowd out pasture grasses. We have had no problems with that, however, and have only seen the plants pop up near mature ones.

Ornamental grass like threadgrass is great for lining pathways.

Gardening Basics

My mantra is “Gardening Should be Fun.” Taking the pressure off makes it more fun. In other words, your garden doesn’t have to look like the cover of a magazine or top Pinterest pages for you to enjoy the process and the results.

So, if you are a new gardener or have a friend or relative who wants to grow plants and doesn’t know where to start, you can watch my online course with the basic terms and concepts. I developed the course for Southwest Gardening Blog, where I am one of four gardeners/authors.

The online class  only is available through February 28, so be sure to sign up soon. You can watch it whenever it is convenient and as often as you like. Have fun with plants!

For Valentine’s Day: 5 Plants With Red Flowers

native rose in bud vase

Roses are red for Valentine’s Day, but there are other plants, including houseplants, bulbs and a few xeric plants that make great Valentine’s Day gifts with their deep red blooms.

Here are my favorites:

Cherry Sage

cherry-sage-bush-in-bloom
Cherry sage, a salvia, is a drought-tolerant plant with bright red flowers.

This xeric salvia (Salvia gregii) is a garden stunner. Add one to your rock garden for all-season color in most regions of the Southwest (zones 6 through 10). Hot lips sage is a perfect plant for lovers with bright red and white blooms.

Poppy

red-poppies
Poppies are beautiful growing in the Southwest garden or pressed in a Valentine card!

Red or Iceland poppies are perfect flowers for pressing and can last a bit as a cut flower. Papaver rhoeas (Red or Shirley Poppy) is a gorgeous complement to other flowers in the garden or planted in a bunch for a bright red meadow.

Geranium

red-geranium-blooms-leaves
Geranium comes in deep shades or red or bright pink and coral.

Geraniums come with deep maroon red, fire engine red or pink flowers. Plant a red geranium and a white geranium in a container for your Valentine. These plants can stay outside in spring or summer in most areas of the Southwest will continue to bloom inside in winter if left in a sunny window. I like to cut the bloom stalk near where the flowers begin and float it in a clear glass container filled with water.

African Violet

red-african-violet-flower-leaves
Tomahawk is a hybrid of the late Kent Stork. The flower is such a deep, rich red.

If the symmetrical rosettes of leaves topped by pretty flowers are not enough (and they should be) to brighten any home or heart, the plant names might do the trick. There are thousands of varieties of African violets hybridized by pros and amateurs with fun registered names. Hybridizers name the violets after loved ones, hobbies and the plant characteristics. There are plenty of varieties with pink and reddish flowers (not just purple ones) .

Amaryllis

amaryllis-blossom-red
The giant, red flower of a holiday Amaryllis.

Many varieties of the winter-blooming bulb come in solid red or white with red or coral streaks. Although most are raised to bloom around the holidays, they can bloom later if dormant and dark for a while, or have a second bloom. I have one that bloomed like crazy in December but has another bud coming up that likely will open just after Valentine’s Day.

red-gladiola-bloom
Gladiolas have gorgeous flowers up and down a strong stem.

Although cut flowers are nice, a plant that can grow on in your garden or home makes a perfect gift for your Valentine. Tulips open outdoors in early spring, and even Claret cup cacti have gorgeous red blooms. My all-time favorite cutting flower is the gladiola and a nice guilty pleasure in an otherwise low-water garden (and protected from munching deer). Or try giving your loved one an anthurium, the tropical plant with a red heart-shaped flower!

The Root of the Matter

 

sprout roots cross section

It’s easy to spot possible problems with a plant’s leaves, stems or flowers. Those are the parts we enjoy seeing every day in our garden. But what about the parts that lie beneath the surface of your garden or container?

We can forget all about the roots when enjoying a plant’s shape and color. But some of the toughest tricks to gardening involve root care – watering enough but not too much; soil drainage to allow roots to gather water but not sit in them; ability for roots to take up oxygen, and ability of roots to grow outward to support the plant you see above ground. How do you know your plant’s roots are healthy and why is it important?

Roots Affect Plant Health

The way roots grow, and their health, have a profound effect on the size a plant reaches, its vigor, and how it responds to watering or other care you give the plant. The main function of these leafless, underground stems is to absorb moisture and nutrients from the soil around them. The roots store the plant’s food to keep it nourished and alive. Roots also help stabilize a plant in the soil or potting mix and physically support the plant’s main stem or trunk.

A carrot is a taproot.

Types of Roots

There are various types of roots, although most root systems branch out under the soil. You might have heard of a taproot, which is a primary root that grows straight down into the soil and develops few to no root branches. Picture a carrot. The part we eat actually is a taproot. That’s the good kind, but a taproot can be a problem for gardeners. Some trees, such as pecans, grow deep taproots. This makes them much more difficult to dig up and transplant.

Some roots have lateral, or secondary, roots that branch off from an existing root. This happens with fibrous roots because their primary root eventually stops lengthening. Fibrous roots are lighter and smaller in diameter because they have less cell activity than standard roots.

One of the biggest problems with roots is restriction of their growth. This is easy to see when you lift a new plant out of its nursery pot. Some have roots circling in the shape of the container; the roots received good nutrition from the potting mix and plenty of water from garden center staff, but had nowhere to go. When planting, always dig a hole larger than the root ball – up to three times as large for trees and shrubs. And loosen the soil around the outer edges of the hole. If the ground is compacted and dense, roots will have to work harder to spread.

wilting zucchini plant from disturbed roots
This zucchini looks bad. Because I ripped its roots when I moved the pot.

A second problem is underwatering (especially a tree) or watering in brief, shallow periods instead of long, deep soaks. Short watering doesn’t penetrate very deeply, so the roots grow close to the surface. And that can bring on other problems, including damage from lawnmowers or foot traffic. But with less frequent and deeper watering, roots grow downward as they seek moisture.

Roots as Plant and People Food

For plants, the structure and quantity of roots help determine how much water and nutrition the plant takes in. That’s why it is so important to water a plant more in its first season or year of growth than it will need later. The extra water helps those roots take hold and grow so they can store food for the plant.

Beet roots and leaves are edible.

 

Aside from carrots, potatoes, sweet potatoes, radishes and beets are among common roots people eat. The mature root – a tuberous root in the case of a potato or sweet potato – holds lots of nutrition.

One final tip – buying a plant that has roots wrapped around inside the pot (rootbound) can make for more challenges when you plant it. You should tease or slice the roots near the outer bottom to help stimulate new growth. But if a plant’s roots are brown or dry, move on to another plant.

 

 

 

 

 

 

 

5 Reasons Succulents Make Great Gifts

Not sure what to give a loved one, friend or co-worker as a holiday gift? You can’t beat succulents. Here are five reasons why:

1. Easy care, even for brown thumbs.

 

Although succulents can die, they are easier to care for than most plants. You can kill them only with kindness (too much water). And even leaves of heat-loving succulents can burn in direct sun. But they make great gifts for people who want a little green but have less than green thumbs. Keep it simple with common succulents like Echevaria or Sempervivum. Both plants come in pretty rosette shapes.

echevaria-sempervivum-in-small-clay-pots
Many succulents have pretty rosette shapes.

2. Succulents make people smile.

Partly because they’re easy, and maybe because of their fleshy, healthy-looking leaves or pads, these plants bring a touch of natural, living matter to the dullest setting. You can find popular ways of displaying succulents as décor. And if the recipient likes to live on the edge, a nice spiny cactus is a fun gift that could be the gateway to growing more houseplants.

3. Succulents grow in lots of container types.

A few weeks ago, I posted about growing cacti in containers. Succulents are so easy to plant in natural, pretty or quirky containers. Small ones can grow in tiny holes of rocks or driftwood. Air plants are even easier to grow in unique containers, since they require no soil.

succulents-in-white-containers
I love these white geometric succulent containers on a patio table in an Austin garden.

4. Adding a personal touch is easy.

So, maybe the succulent you choose for a gift isn’t so unique, but you plant it in a coffee cup with a message, or a souvenir that has sentimental value. You can use your sense of humor or a little romance when choosing how to present a small succulent – or several. Or select one based on the name (maybe String of Pearls?) You also can make your gift more personal with a small set of instructions on how to care for the plant. You can look for information online or write up how you take care of succulents.

succulent-in-metal-container
An old metal container with sentimental value holds this succulent.

5. They’re popular and available.

The trend in succulent plantings, arrangements and decoration on all sorts of materials might not last forever. But while it does, it is easy to find a great selection of succulents for gift-giving.

Your local nursery greenhouse is sure to be loaded with lots of succulent choices.

Here are some favorite small succulents:

Echevaria, several varieties

Sempervivum (such as hens and chicks)

Sedum morganianum (Burro’s tail)

Euphorbia milii (Crown of Thorns) and it is thorny!

Crassula ovata (Jade plant)

Mamillaria crinita (Pincushion cactus)

Haworthia fasciata (Zebra plant)

haworthia-foliage
Harowthia is such a fun succulent, and it can send up a stem with yellow flowers.
