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?

A Garden Photo Contest

Are you a gardener? Do you take photos of your plants? If so, you might want to know about the National Gardening Association’s annual photo contest.

I hesitated to share this with you—after all, I intend to enter and advertising the contest just increases my competition. On the other hand, I love seeing the pictures other photographers create. You give me ideas. You inspire me. I can learn from you.

If you need some help, I’ll be posting a series on garden photography—after the contest ends! ( I know. I’m being mean.) Meanwhile, you can look at all the photos I’ve included in my garden posts over the years. Then check out the series I did a while back on bird photography. Many of the techniques and tips are the same. Simply type “photography” in the blog search box, or choose “Photography” from the drop-down category list at right.

I’ll look forward to seeing your entries.

Do Houseplants Reduce Stress?

Are you stressed? You should grow houseplants! Just ask all the experts. Try an online search and you’ll come up with almost two million sites claiming that growing plants reduces stress. Even the National Institute of Health has jumped on the bandwagon with a study “proving” that houseplants reduce both physical and psychological stress, at least in young men.

Unlike the articles that tout huge benefits in air quality from including plants (especially spider plants) in your home (NASA said it so it must be true—but see my post here), there may actually be some basis for the stress-reduction theories. Or not.

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…)

Good Vibrations

Stachys byzantina - Lambs Ears @DBG LAH 004
Is that why they’re called Lamb’s Ears?

Can plants hear? At first glance, this seems like a silly question. Plants don’t have ears, so of course they can’t hear. But wait—do organisms need ears to hear? What is hearing, anyway?

Given that sound consists of a series of vibrations that are propagated through air, water, or another substance, then hearing must be the ability to sense those vibrations. And while our ears are very good at sensing vibrations, there are other options.

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…)

Save the Seeds

Poppy seedheadsWhile we haven’t had a hard freeze yet, the lack of warm sunshine is telling my plants that the season is about over. Poppy seedheads act like salt shakers—just invert and shake out the seeds. We missed harvesting some pole beans and they’re now overripe, the pods puffy and enlarged. I’m letting them dry on the vine.

I let some of the cilantro mature and bloom, as the flowers attract lacewings and other beneficial insects. Parsley is a biennial, and I overwintered last year’s crop; it also bloomed this summer. Both are producing more seeds than I will ever use. (more…)

Don’t Wait. Plant Now.

Plants for sale @Lowe's-CS_2008aug02_LAH_5093If the cooler weather and turning leaves haven’t alerted you, the calendar can’t lie. Tomorrow is the first day of autumn. Can our first frost be far behind? It’s tempting to let the change of seasons put a stop to gardening for the year, but there’s still much to do. (See my previous post on “Putting Your Garden to Bed” for ideas.) Of course we know that many spring-blooming bulbs go in the ground now. But how about perennials, shrubs, and even trees? Can we plant (or transplant) them now? Even for those of us who live in places with cold winters, fall is a terrific time to plant.

A Visit to Missouri Botanical Gardens

MissouriBotanicalGardens-St.Louis-MO_LAH_3036

Late August isn’t the best time to visit most gardens, but that was when I had the opportunity to visit the Missouri Botanical Gardens. I’ve used their horticultural database for years. It’s one of the most extensive online resources available to those of us who want to learn more about plants. Home gardeners in particular should check out the Plant Finder, which offers helpful information on plants you might grow in your yard (just remember, Missouri isn’t Colorado!). Now I had a chance to see the gardens in person. I could hardly wait! (more…)
