I Love Veronicas

Veronica peduncularis 'Georgia Blue' @DBG LAH 171rs

It looks like the sky has fallen and landed among my perennials. Purple-blue flowers formed a dense carpet nearly obscuring the thick layer of green foliage underneath—and the whole show was only a few inches high. I have a weakness for “blue” flowers (when it comes to botanical descriptions, usually that means purple), and the various speedwells are at the top of my list.

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!

Garden Hopping

Gazebo_HASDemoGarden-COS-CO_LAH_9487As an enthusiastic gardener, I spend a lot of time in my yard, but it’s always a treat to visit other gardens. Just as sandwiches always taste better if I don’t have to make them, a garden I haven’t tended seems more lovely somehow. Perhaps it’s because I’m not responsible for pulling every weed; I can just relax and enjoy the flowers.

I’ve been garden hopping a lot this month. Earlier this month, our house suffered 45 minutes of half-inch hail accompanied by a torrential downpour. Runoff scoured my gravel paths and adjacent flower beds—I  never did find some seedlings I had just planted. Happily, other parts of town completely missed the destruction. I find their intact flowers and un-shredded leaves therapeutic, easing my bruised sensibilities while my garden heals. (more…)

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?

A Flower of the Gods

dianthus-tiny-rubies-1Just as each month is associated with a particular birthstone (January’s being a garnet), so is each month paired with a particular flower. According to folklore, each of these flowers symbolized specific characteristics, which were in turn assigned to those born during that month. While some claim this custom arose with the Roman empire, I suspect that the florist industry might also have had something to do with it.

Well, it turns out that January’s “birth flower” is the carnation. Carnations are on my Top Ten list of flowers. They’re pretty, typically inexpensive, last a long time as a cut flower, and have a scent that I swoon over. Apparently, I’m in good company. Their genus, Dianthus, comes from the Greek for “flower of the gods.” How appropriate! (more…)

Watering Trees

dead tree_COS_PLH_3The tree had clearly expired. What leaves remained had turned a sickly yellow-brown, and hung limply on the branches—in mid-August! Yet, when our neighbors planted it last year it had been perfectly healthy. Something was obviously wrong, and I had a hunch I knew what. (I’ve often said that master gardeners kill just as many plants, we just know why they died.)

Surreptitiously moving the cobblestone mulch aside (and wondering if the homeowner was watching through the closed curtains), I looked at the drip irrigation set-up. There was only one emitter, and it was directing water right to the base of the trunk. No wonder the tree was dead! (That and the fact that it was planted too deeply; there’s no sign of the root flare.)
