Moth Orchids

Orchid_2943_filt_rel

With the holidays behind us, winter seems to stretch out as far as we can see. I don’t know about you, but I’m more than ready for a tropical vacation! We can’t afford tickets to a balmy beach or verdant rainforest, but I can manage to plunk down a mere $19.95—or less—for a blooming orchid. My imagination will have to supply the rest.

Persistent Perennials

Lychnis coronaria - Rose Campion @DBG LAH 033We had our first hard freeze over a month ago. Most of the deciduous plants and perennials in my yard are now dormant—some with dry brown leaves still attached, others with bare stems. But remarkably, not everything looks dead. In fact, a surprising number of plants still sport green foliage.

I’ve often chosen or rejected a plant for my garden based on when it leafs out in the spring. Too early and the tender new leaves are withered by a late snow. Too late, and half the season is gone before the yard looks complete. But I never considered the other end of the season—how long will the plant stay green before going to sleep for the winter?

Poisonous Leaves

Poison Ivy_Columbus-OH_LAH_3634I was happily photographing wildflowers along the edge of a park in Ohio when our friend, a local, warned me, “Don’t touch that!” I looked down. That plant looked familiar—a sprawling, low-growing shrub with reddish stems and shiny green leaves, each comprised of three leaflets. Wasn’t that…?

Yes, and thankfully I hadn’t actually touched any of it. It’s rather important that those of us who enjoy hiking be able to recognize poison ivy and other plants in the genus Toxicodendron. Toxicodendron means “poisonous leaf”—pretty appropriate for plants whose leaves contain urushiol, an oily chemical that frequently triggers an itchy allergic rash, or worse. (more…)

Rhus trilobata: A Winner by Any Name

Rhus trilobata_Three-leaf Sumac_DenverZoo_20091007_LAH_3355.nef

All summer, the shrub sat in the back corner of our yard, quietly filling the space between the fence and a dry creek bed. The olive-green leaves were a bit drab, but provided a nice, neutral backdrop for an adjacent Blue Mist Spirea (Caryopteris). The shrub had been a bit late to leaf out, and I was contemplating replacing it with something more interesting. I’m glad I waited. In the last few weeks, that inconspicuous shrub has suddenly become the star of the garden. (more…)

(Not Just) Purple Coneflower

Echinacea purpura_Purple Coneflower_XG_ColoSpgs-CO_LAH_5655

Purple Coneflower (Echinacea purpurea) used to be purple. You can still buy the purple-flowered version of this perennial (actually more of a pink, at least to my eye), but purple is only the beginning. Consider passionate hues such as raspberry pink and florescent orange. On the other hand, perhaps you’d prefer delicate pinks, or even an innocent snowy white. A related species, E. paradoxa, below, is a pure lemon yellow.

Impressive Pineleaf Penstemon

 

Penstemon pinifolius - Pineleaf Penstemon @SantaFeGreenhouses 20089jun28 LAH 067Looking for a small perennial with a big impact? Consider Pineleaf Penstemon (Penstemon pinifolius). True to its common name, this low-growing plant has long, narrow leaves similar to pine needles. They hang on well into winter, and may be evergreen even in some colder climates. But it’s the flowers that steal the show. The dense mass of vivid scarlet red simply takes your breath away!

Charming Saponaria

It’s such a pretty plant, petite and delicate, only a few inches high and covered with quarter-inch flowers of the softest pink. It’s the kind of groundcover perfectly suited for small spaces, rock gardens, and fairy bowers. It can even be used as a lawn substitute, as it tolerates limited foot traffic. With so much to recommend it, I’ve often wondered why this hardy perennial isn’t more popular. Perhaps it just needs a better name. “Soapwort” fails in the marketing department!

Bearded Irises

Iris hyb_DBG_LAH_0592

If you’re looking for an indestructible perennial to grow along Colorado’s Front Range, you can’t beat bearded irises. They’re tough, hardy to zone 3. They’re drought tolerant. They aren’t fussy about soil. Deer and rabbits leave them alone (for the most part). And they come in nearly every color in the rainbow—and then some. How can you lose?

Lungwort—Prettier than it Sounds

Pulmonaria_Lungwort_DBG-CO_LAH_4436

It’s easy to understand why we want to include Sweet William, Lamb’s Ears, or Love-in-a-Mist in our gardens. Their whimsical names make us smile. On the other hand, it’s surprising anyone grows plants with names such as fumewort, blood lily, or wormwood. They sound awful! In fact, these plants are quite beautiful, as you can see below (clockwise from upper right).

Violas Make Me Smile

viola-sp_violet_dbg_lah_4917What genus of flower is beloved by millions? Comes in every color of the rainbow (except green), plus black and white? Has species native to Hawaii—and the Andes? Can bloom through the snow in the dead of winter? Is tolerant of wet soil—or survives drought? Handles full sun or shade with equal enthusiasm? Includes annuals, biennials, and perennials? Always elicits a smile? Is the “birth flower” of February? The lowly Violas—which include pansies and violets—are all this and more.
