first salad

Written on April 5, 2012 at 11:33 am , by

A blend of lettuces dressed with crumbled blue cheese and croutons is a springtime dinner treat.

Salad season has arrived. I devoured the first salad from the garden last night for dinner. This first batch of salad greens came from various lettuces, spinach, and corn salad that overwintered in the garden with no protection, a first-time occurrence in my Des Moines garden.

I could have harvested them earlier, but I’ve been traveling so much lately that I’ve not had the opportunity to do so. The outlook for more springtime salads from the garden looks rosy. The early-March planting of lettuce and spinach is almost ready to reap as well. I should thin them and use the rejects as gourmet baby greens.

Radishes from the garden are also ready to pick. These first red orbs are sweet and mild because they have matured quickly in the pleasant spring weather. Now if my tomatoes would just ripen in the next two weeks…….!

Fingernail-sized radishes will add color to spring salads.

Recently seeded rows of lettuce and spinach are ready to thin and use in salads.

springtime in the Ozarks

Written on March 30, 2012 at 10:51 am , by

Spring break for me this year was a week-long road trip through the Ozarks. In addition to visits with family and friends at Long Creek Herbs in southern Missouri, friends in Fayetteville, AR, and a side trip to the Clinton Library in Little Rock, public gardens were part of my must-see agenda. The timing was perfect. An unseasonably warm spring had coaxed redbuds and flowering dogwoods, into bloom, covering the hillsides with splashes of color. In town, lilacs, spireas, and spring bulbs were displaying their finery.

Eureka Springs, AR is a unique historical town with winding streets perched on hillsides. Nearly a dozen springs bubble up from the rocky outcroppings, and the town has turned the areas around each into pocket parks. The display of violas and painted twigs below, was at one of these mini-parks located, appropriately enough, on Spring Street.

Compton Gardens in Bentonville, AR features native plants of the Ozarks. This is the former estate of Dr. Neil Compton, who was instrumental in saving the Buffalo River as part of the National Park Service. Walkways through the grounds guide visitors to displays of groomed native plants. The trail system also connects to Crystal Bridges, the fantastic new museum of American art.

Golden ragwort (Senecio aureus) is a native wildflower with yellow daisylike blooms in spring.

Carolina silverbell (Halesia tetraptera) is a native tree with springtime blooms that resemble dangling white bells.

The Botanical Garden of the Ozarks is a relatively new public garden, but it has a lot to offer including a children’s garden, butterfly house, rock garden, water garden, native garden, sensory garden, vegetable garden, and Japanese garden. Despite constant rain during my visit, I was able to snap a few photos, including a planted concrete chair, obviously not intended for seating.

Hens and chicks cover the seat cushion on this whimsical "chair" next to the children's garden at the Botanical Garden of the Ozarks.

This Euphorbia martinii Ascot Rainbow was in full bloom at the Botanical Garden of the Ozarks.

 

early spring flowering shrubs

Written on March 22, 2012 at 10:43 am , by

Flashy golden forsythias and splashy pink saucer magnolia take center stage in many early spring landscapes. But these leading ladies aren’t the only shrubs that can make an impact in your yard at this time of year. Many other woody plants are worthwhile additions for their vernal display of showy blooms. If you’re looking for something a little more unique, consider one of the beauties shown below.

Hybrid witch hazel (Hamemelis X intermedia) kicks off the spring season with its straplike gold or copper petals, usually blooming in February.

White forsythia (Abeliophyllum distichum roseum), also called Korean abelialeaf, is neither a forsythia nor an abelia, although it has qualities resembling those shrubs. It precedes the yellow blooms of true forsythia by a week or more.

Double Take 'Pink Storm' flowering quince (Chaenomeles Double Take 'Pink Storm') bears clusters of rosy pink blooms backed by glossy clear green foliage.

Flowering almond (Prunus glandulosa 'Rosea Plena') grows just 4 feet tall and in spring is covered with fully double pink blooms.

Regent serviceberry (Amelanchier alnifolia 'Regent') is a season-long beauty. The white spring flowers are followed by tasty purple-blue fruits, and the leaves turn gold, orange, and red in fall.

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.

Ladies and gentlemen, start your onions!

Written on March 1, 2012 at 11:34 am , by

Gardening with vegetables and annual flowers is a race against time and the elements. If you jump the gun, spring frost may knock back tender seedlings. If you delay too long, yields may be reduced because plants won’t fully mature before fall freezes arrive or the excessive heat of summer stymies growth. Onions are an example of a plant sensitive to day length. Varieties adapted to the northern U.S. form biggest bulbs during the long days of June and July. Delayed planting results in decreased bulb size because they form during the shorter days of late summer.

In response to this year’s mild winter, I’m betting on an early spring. I seeded onions in the greenhouse in mid-January. The seedlings are up and growing strong, and will soon be ready to transplant into the garden. If you haven’t started onion seeds yet, you can still direct seed them in the garden, purchase transplants from a garden center, or plant onion sets.

Seedlings of onion and annual flowers grow quickly in a large box with a seedling heat mat to provide bottom heat.

This weekend I’ll be starting dozens more vegetables and annual flowers in the greenhouse seed-starting chamber. When seed orders arrive, I file away seed packets by planned start date, storing them in the extra refrigerator in the garage to prolong their viability.

Store garden seeds in air-tight containers in the refrigerator to keep them fresh longer.

I did a quick inventory of seed packets to start on March 1, and came up with the following list of things that I’ll be planting this weekend.
Flowers:
Salvia ‘Summer Jewel Pink’ (an All-America Selections winner for 2012) and ‘Blue Victoria’;
Dianthus ‘Parfait Raspberry’;
Celosia ‘New Look Red’;
Gomphrena ‘Dwarf Buddy’ and ‘Qis Purple’;
Baby’s breath ‘Gypsy Deep Rose’;
Lavatera ‘Hot Pink’;
Marigold ‘Hero Bee’;
Snapdragon ‘Twinny Rose Shades’;
Lobelia ‘Crystal Palace’

Vegetables:
Tomato ‘Lizzano’, ‘Terenzo’ (AAS winners for 2011), ‘German Johnson’, ‘Mortgage Lifter’, ‘Pruden’s Purple’, ‘and ‘Pompeii’;
Pepper ‘Black Olive’, ‘Cayenetta’ (AAS winners for 2012), ‘Odessa Market’, ‘Corno di Toro Giallo’, ‘California Wonder’, ‘Gordo’, ‘Premio’;
Eggplant ‘Black Beauty’;
Basil ‘Queenette’ and ‘Mrs. Burn’s Lemon’;
Broccoli ‘Liberty’, ‘All Season’s Blend’, and ‘Romanesco’;
Cauliflower ‘Grafitti’;
Chinese cabbage ‘Little Jade’ and Michihli’;
Lettuce ‘Garden Babies Butterhead’;
Beet ‘Bull’s Blood’

I’ll wait several weeks to start quick-growing heat lovers such as zinnias, squash, and ornamental cotton. By then, I’ll move frost-hardy annuals to the covered deck or front porch to acclimate to outdoor growing conditions. They’ll grow slower there than in the greenhouse, but as the adage goes, “slow and steady wins the race”.
