Crocus plus

Written on March 15, 2012 at 11:31 am , by

After a couple of days with record warmth in the 70s and 80s, early spring bulbs are displaying their vernal glory in my yard. As of March 14 the landscape features eight different types of crocuses, three iris varieties, three kinds of daffodils, spring meadow saffron, snowdrops, winter aconite, and pasque flower in bloom. This early color may not last long because temperatures are predicted to remain in the 70s through next week, but it’s such a welcome sight to see splashes of color dotting the yard before winter officially makes its exit.

Here are some current photos from the yard.

My favorite crocus is Crocus fuscotinctus. Its bright gold flowers have purplish maroon stripes on the outside of the petals, and it's always one of the first to come into bloom. It's growing near the mailbox, where it withstands winter road salt.

It's easy to see where the tricolor part of the name comes from for Crocus sieberi 'Tricolor'. Lilac-purple petals have a golden base with a stripe of white in between.

Crocus vernus 'Grand Maitre' translates as Grand Master, an apt name for this gorgeous purple crocus with an intricately frilly orange stigma.

Crocus flavus has large, intense yellow blooms that open wide only when the sun is shining. On cloudy days and at night, they close up.

Spring meadow saffron (Bulbocodium vernum) is a crocus cousin native to the Pyrenees and Alps. It is sometimes called Colchicum vernum.

Spanish iris (Iris hispanica 'George') has deep purple blooms with colorful markings on its nearly tubular falls. It grows nearly one foot tall.

Reticulate iris (Iris reticulata 'Harmony') has purple-blue petals with distinctive markings on its falls. It reaches just six inches tall.

plant a flower day

Did you know that March 12 is Plant a Flower Day? I don’t need much of an excuse to plant flowers. I already have several dozen types of annual flowers started in the greenhouse, including the All-America Selections winners for this year (see below), and one from last year.

Salvia coccinea 'Summer Jewel Pink' is a 2012 All-America Selections Bedding Plant Award Winner that I think will look great in my pink border. Photo courtesy of All-America Selections.

Vinca 'Jams 'N Jellies Blackberry' is a 2012 All-America Selections Flower Award Winner. I can't wait for the seedlings that I've started in the greenhouse to start blooming. Photo courtesy of All-America Selections.

'Glamour Red' ornamental kale was a 2011 All-America Selections Cool Season Bedding Plant Award Winner. It looked great in my garden into December, so I'm growing it again this year. Photo courtesy of All-America Selections.

It may be a bit premature to plant perennials here in Des Moines, but I have some on order from High Country Gardens that will expand my collection of Midwest and High Plains native perennials. A few of them are pictured below. They’re scheduled for arrival in mid-April. By then, I’ll be able to plant them directly in the garden.

Which new flowers will you be growing in your yard this year?

 

Zauschneria garrettii is sometimes known as hardy fuschia as well as hummingbird trumpet. The bright orange tubular blooms draw hummingbirds to the garden.

Penstemon cobaea purpureus is a type of beardtongue with foxglove-like blooms on stalks several feet tall. It is a Midwest native.

Whether you call it redbirds in a tree or New Mexico figwort, Scrophularia macrantha is a cute perennial for dry sites with its panicles of rosy red blooms on compact plants.

indoor plant projects add beauty

If you’re ready for spring to arrive, but the weather isn’t quite cooperating, why not plan and plant an indoor garden project? During a photo shoot last week for an upcoming book on indoor gardening, I completed several projects featuring bromeliads and a couple involving converted indoor fountains. Use your imagination to come up with unique containers for terrariums and dish gardens. The results will enliven your indoor living spaces and help bridge the time until you can dig in the garden outdoors.

This former slate fountain now houses 'Bright Star' dieffenbachia and 'Brasil' philodendron. 'Millenium' variegated English ivy trails from the top of the fountain.

This wreath of air plants (Tillandsia spp.) is easy to make with a double-wire wreath ring, a hot glue gun, a collection of air plants, and a wreath hanger.

A former slate waterfall fountain cradles air plants (Tillandsia spp.) at each level. The plants need only water and bright light to thrive.

These air plants (Tillandsia spp.) were glued to a piece of wood and propped up in a tall vase that serves as a terrarium. The glass marbles prevent the stick from shifting.

Earth stars (Cryptanthus bivittatus) are terrestrial bromeliads. Here they're planted with moss and decorated with glass marbles in a shallow microwave baking pan.

bromeliads for valentine’s day

Bromeliads are easy-care indoor plants that pack a punch of color for months on end. Rather than giving your valentine flowers with fleeting color, consider giving a lasting gift of one of these beauties. (While you’re at it, pick up one for yourself too!)

All that these undemanding plants require is bright light and occasional watering. The varieties that form cuplike rosettes make watering a snap. Simply fill the “cup” with water, allowing a bit extra to drip down to the soil. Types with scaly silvery foliage (sometimes called air plants) thrive with twice-weekly misting or dunking.

Because they are tropical in origin, bromeliads appreciate comfortable room-temperature conditions. You can move them outdoors to a shaded location for the summer, but protect them from frost.

'Valentina' is a new variety of guzmania, appropriately named for gift giving to your sweetheart. Its combination of green straplike leaves, bright red bracts, and tiny white flowers is stunning.

Blushing bromeliad (Neoregelia carolinae 'Tricolor') develops a reddish pink blush on its green and white striped leaves when it blooms. The flowers are often hidden in the plant's vase, but the colorful foliage steals the show anyway.

Silver vase plant (Aechmea fasciata) pushes up a starburst of pink bracts and small purplish blue flowers from its silvery vase of foliage.

Pink quill (Tillandsia cyanea) is an air plant bromeliad. Its bright pink bracts remain even after its purple flowers fade.

Earth star (Cryptanthus bivittatus) makes a sculptural statement in a mixed planter. Its cream, rose, and green stripes attract attention.

dive into coleus

Here are portraits of some of the Under the Sea Series of coleus. Top row l. to r.: Bonefish, Gold Anemone, Hermit Crab. Bottom row: Lime Shrimp, Moten Coral, Sea Scallop.

Coleuses have undergone an amazing transformation in the past few years. No longer relegated to the dark corners of the garden (although they still fill that role admirably too), the brightly colored foliage of coleuses can now take center stage in full sun thanks to numerous sun-tolerant introductions. At this year’s American Nursery and Landscape Association Clinic, the Under the Sea Series of coleus from Hort Couture won the Garden Idol award, meaning it was the favorite of attendees. Plants in this series are characterized by extreme frills and dazzling colors reminiscent of life on a coral reef. The ones that I’ve seen growing in the garden add an exciting element of texture paired with stunning colors.

The aptly named Under the Sea coleus series takes my thoughts back to the days when The Little Mermaid movie was first released, and the song, ‘Under the Sea’ was popular, at least among the elementary and pre-school set, of which my daughters were a part at the time. I remember them performing that song with their friends at a 4-H talent show. They didn’t come away with any American Idol awards, but getting up on stage and performing was a good experience for them. As they sang,
“The seaweed is always greener
In somebody else’s lake…
Just look at the world around you
Right here on the ocean floor
Such wonderful things surround you
What more is you lookin’ for?”

Indeed. I have a bench of coleuses in my greenhouse, just waiting for spring to arrive. I can’t wait to create islands of color with them in the landscape. Look for Under the Sea coleus at independent garden centers this spring.

Trends in indoor gardening

Written on January 26, 2012 at 10:20 am , by

The Tropical Plant Industry Expo is the place to go to see what’s hot in indoor gardening. The fact that it’s held in southern Florida in mid-January, is another incentive to attend! Trends that I saw this year include a resurgence in the popularity of terrariums and dish gardens. But these aren’t simply a return to mass-produced fad gardens from the 1970s. Modern mini-landscapes have more style and individuality. Often they’re displayed in unique containers or feature sculptural plants. The emphasis is on tough, easy-care plants such as succulents and bromeliads. Here are some examples that I saw at this year’s Expo.

The ribbed glass on this terrarium adds a unique perspective, resembling a pumpkin. It makes a great centerpiece.

The ceramic base on this terrarium hides the soil and root zone while displaying the foliage clearly.

Put that cupcake holder to use displaying begonias, ferns, peperomias, nerve plants, and miniature palms.

Spikes of maroon Dracaena marginata explode from a bed of heavily patterned peacock plant (Maranta) in this combo.

These earth stars (Cryptanthus), a type of bromeliad, look other-worldly when displayed on a pedestal.

Echeverias, kalanchoe, and peperomia team to create amazing texture and color in this succulent dish garden.
