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!

In Praise of Poisonous Plants

Convallaria majalis_Lily of the Valley_HudsonGardens-CO_LAH_5740Maybe hemlock has the right idea.

I’ve always avoided incorporating poisonous plants in my garden. When our children were small, I was worried that they would eat a leaf or berry. Now we have small grandchildren who come to visit. Years ago, back in California, we tore out the oleanders and privets, replacing them with artichokes, strawberries, and other “edible landscaping.”

Plant Science for Gardeners

How Plants WorkNew gardening books seem to pop up as regularly as springtime dandelions. Most simply rehash what has been said before—perhaps with a new twist or better photos. But How Plants Work: The Science Behind the Amazing Things Plants Do (Science for Gardeners) isn’t your typical treatise on how to grow what. Instead, the author, Linda Chalker-Scott, explains the “why” behind the “how.”

An extension urban horticulturist and associate professor at Puyallup Research and Extension Center, Washington State University, Chalker-Scott knows what she’s talking about. This is her third book on horticulture, but there is a lot more. She’s written a series of articles on “Horticultural Myths” that I strongly urge you to read. Then, learn more at “The Informed Gardener,” a series of podcasts, or the informative Garden Professors website. She’s also a driving force behind the Gardening Professors Facebook blog (an extremely helpful research-based Q&A site).

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?

Snow-tolerant Veggies

Yes, it’s May. And yes, it’s still snowing. In fact, we had temperatures around 20 degrees, with snow, over the past few days. The prediction is for warmer weather, but in previous years we’ve had snow and lows below freezing well into June. Of course I’m anxious to get my garden growing—but what will survive our winter/spring weather? Surprisingly, quite a lot!

Kale
LAH_7318We were gone last fall, so I never got around to pulling out last summer’s freeze-killed veggies. It turns out that was a good thing. With no protection at all, my Starbor kale roots survived our Zone 4 winter, and new growth is appearing from a dead-looking stump. I expect the kale plants to bolt as soon as it warms up a bit more, but in the meantime, I’m harvesting kale now. I plan to include kale in my garden again this year, starting seeds inside and setting out plants in late June to mature in September and October, after frost sweetens the leaves. You can bet I’ll leave those plants in place next fall, maybe with a bit of mulch or a row cover, for yet another early harvest. (more…)

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).

Moss, the Weird Plant

Moss_SpruceGrove-Tarryall_20090626_x-001

Moss. To those of us in Colorado, moss conjures images of soft green blankets cushioning the forest floor, or carpeting the north side of a tree in a verdant forest. To my daughter in western Washington, moss is that soggy green mat choking out the turf in her shady backyard, or keeping the shake roof too wet, allowing rot to set in. But love it or disparage it, moss is one fascinating plant.

Houseplants & Indoor Air Quality

spider-plant-home-28mar2006-lah-123rI’ve been down with a nasty stomach virus for the past week, more interested in the distance to the bathroom than in gardening. As a result, I’ve been perusing articles instead of writing them (it takes far less effort!). I’ve also spent considerable time reading bogus gardening advice on Pintrest—it’s an amazingly rich repository of horticultural mythology. One afternoon I focused on the idea that houseplants purify the air in our homes. We’ve all seen the articles…
