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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Christmas Cactus: You Can Grow That!

Holiday flowers like paperwhites and amaryllis are fun and beautiful, but in the Southwest, we love succulents, and the Christmas cactus (Schlumbergera bridgesii) is a fall and winter favorite in our homes.

The Christmas cactus loads up with delicate flowers each winter, assuming you take a few steps to force the blooms. That might sound intimidating, but it really is simple. The blooms appear on small, flat “leaves,” which are really stem segments. Closely related plants – all with a holiday “theme” – are the Thanksgiving cactus (S. truncates) and the Easter cactus (Schlumbergeragaertneri). You can guess the approximate times each should bloom. There are some differences in the stem shapes, but overall care is similar.

Schlumbergera plants were discovered in Brazil’s rain forests, where they grow as epiphytes on trees or other plants without stealing their nutrients.  That makes them less parasitic than another holiday favorite, mistletoe.

The flowers have a long, tubular shape and truly are remarkable, especially considering they appear on an indoor succulent! Between all schlumbergera varieties, you can find red, salmon, white and orange blooms, as well as some bicolor flowers.

Here’s how to get your Christmas cactus to bloom: Place it in a dark closet in fall, usually around late September or early October. Once buds begin to form on the ends of the stem sections, after about a month or two of darkness, bring the plant out into natural light, but not to an extreme temperature or direct sunlight.

Christmas cactus thrives best in indoor temperatures (about 55 to 70 degrees F). Even though these are cacti, they come from a naturally humid setting. Mist the leaves from time to time and let the soil barely dry out between watering so it is consistently and lightly moist, but don’t overwater or let the plant sit in water.

Once your Christmas cactus blooms, the flowers last about a week, assuming they get some sun and appropriate water. The chain of blooming should last about a month. Some say the plant is unattractive when not blooming, but I disagree. I find the cascading form of the stems and their thick, succulent appearance attractive all year.

The fleshy stems of a Christmas cactus are attractive even when it lacks blooms.

This plant is easy to grow, and you often get blooms without following any of the advice about dark periods. We’ve had blooms at various times of the year, and I’m okay with that. I just enjoy the plant, no matter when it rewards us with those fabulous flowers. You can find Christmas cactus in nurseries and just about anywhere this time of year. The plant makes a great gift.
