Cottonwood Creek’s Xeriscape Garden

cottonwoodxg_lah_2470Successful gardening in Colorado means choosing plants well suited for our arid climate. Colorado Springs Utilities (CSU) maintains two demonstration gardens, featuring beautiful perennials, grasses, shrubs and trees that are adapted to limited irrigation. Many people are aware of the large garden at the CSU headquarters on Mesa Road, overlooking Garden of the Gods. I wrote about it in April. But very few people are aware that there’s a second, smaller garden in front of the Cottonwood Creek Recreation Center at 3920  Dublin Blvd., just west of Rangewood Drive.

iris_cottonwoodxg_lah_2504While much more limited in scope, this garden provides plenty of inspiration for a homeowner seeking to conserve water and still enjoy a beautiful landscape. When I visited in mid-June, a large swath of Stella ’d Oro daylilies were in full bloom, their bright golden yellow accented by the soft lavender of the surrounding Walker’s Low Catmint. The colors were repeated in lovely deep blue irises, purple Jerusalem Sage, and pastel yellow Moonshine Yarrows and Pineleaf Penstemon.

Colorado Gardeners Need Colorado Garden Advice

The ad promised that this new gardening book would show me how to “chase those darned moles out from under my prize tomatoes … make … azaleas bloom like crazy … and [use] eggshells [to] barricade slugs from the hostas, cabbage, and lettuce.”

Sounds wonderful, right? The problem is, while those “garden cheats” (as the ad called them) may work in much of the country, particularly in the east, not one of those will work here in Colorado.

Balloon Flower (Platycodon grandiflorus)

Appearance
platycodon-grandiflorus-albus-balloon-flower-dbg-lah-321r-1We may not be able to grow real balloons in our gardens, but Balloon Flower comes pretty close. Large buds shaped like inflated balls give Platycodon its common name, Balloon Flower. These buds open into showy blue, pink or white blossoms shaped like plump, five-pointed stars. The flowers adorn one- to two-foot tall vase-shaped clumps of oval green leaves.

Cultivation
platycodon-grandiflorus-balloonflower-dbg-lah-002rGrow Balloon Flower in well-drained garden soil amended with several inches of compost. Mark the spot so you remember where the plants will reappear in late spring. These perennials take several years to look their best, but your patience is rewarded with plants that live for twenty years or more. Because they stay neat and well-behaved, dividing is unnecessary; in fact, the roots hate to be disturbed. Established plants survive some dry periods, but prefer regular watering.

Landscape Use
Growing happily in sun or partial shade, the informal flowers are especially appropriate for a cottage garden or woodland. Bloom starts in mid-summer, often continuing until frost. Suggested companion plants include Sweet William, columbine, and daylilies in complementary colors.

Plant Fall Crops Now

Plant? NOW?

brusselssprouts_dbg_lah_7726Temperatures are climbing into the 90s, your spring-planted crops are reaching maturity, and you’re excited about garden fresh salads and new potatoes. Besides harvesting your bounty, there are millions of weeds to be pulled, poisoned, or decapitated. The last thing on your mind is planting more seeds.

In more benign climates, fall crops go in at the end of the summer, after the worst heat has passed. Our short season demands that we plant fall crops earlier, to give them time to mature before the snow flies. Now is the time.

Visit the Carnegie Library Garden

carnegielib-cospgsco_lah_9982The Carnegie Library Garden may be one of downtown Colorado Springs’ best kept secrets. That’s a shame, because it is truly a gem. This is one of several public gardens featuring water-wise plants especially suited for our climate and soils. It was designed by landscape architect and master gardener Carla Anderson, and is maintained by a team of dedicated volunteers.

rosa-hyb-pinata_carnegielib-cospgsco_lah_0081Blossoms abound throughout the growing season. When I visited last month, red and yellow ‘Lena’ broom was beginning to fade, while several types of Mockorange were in full bloom. Rosettes of huge, fuzzy, silver Salvia leaves were topped with tall white or purple flower stalks, and brilliant Colorado Gold hardy gazanias were everywhere. An arbor with a built-in bench supports a beautiful pink climbing rose, while honeysuckle grows on up a nearby trellis. By the time you read this, new plants will be in bloom; it’s worth coming back for repeat visits.

Upside-Down Tomatoes?

tomatoes-greenhouse-2008sept08-lah-296We’ve probably all seen the ads for growing upside-down tomatoes, with the plants protruding from the bottom of a hanging plastic bag full of potting mix. They’re the Big New Idea in gardening. The question everyone’s asking is, does this work here in Colorado? After all, this isn’t exactly prime tomato-growing country.

Carol O’Meara is the horticultural extension agent for Boulder county. She has decided to find out for herself if growing tomatoes upside-down works in our climate, and is sharing the ongoing results of her experiment on her blog, Gardening After Five. Carol brings up a number of important issues; if you want to try this too, reading her article is a good place to start.

Boulder Raspberry (Oreobatus deliciosus)

Appearance
rubus-deliciosus-boulder-raspberry-emeraldvalley-2008jun23-lah-004r
With its ostentatious white flowers clamoring for your attention, Boulder Raspberry impresses like a hybridized cultivar, rather than a native shrub. Growing three to five feet tall and six feet wide, arching, sprawling stems carry bright green, lobed leaves that turn yellow in fall before dropping for the winter. Spring’s blooms develop into small reddish purple fruit resembling cultivated raspberries. While edible, the berries are generally considered unpalatable. However, they will attract birds and other wildlife to your garden. Unlike other raspberries, the stems are thornless.

Landscaping with… Zucchini?

Squash blossom @home 2008sept23 LAH 253Roses, petunias, and … zucchini? Why not? While traditionally grown in a vegetable garden, summer squash’s striking appearance can provide a focal point for an ornamental border as well.

Zucchini and its relatives have large lobed leaves, blotched with white, supported by thick prickly stems. Big yellow flowers produce squash in an amazing variety of colors and shapes. Of course they’re edible—but they’re eye-catching as well. Just make sure you leave plenty of room. “Bush” squash plants grow four feet wide and two feet high.

Get your Goat

goat-eidahostatefair-2007sept08-lah-585While taking a break and perusing an assortment of gardening websites, I stumbled across this story at “Dave Hobson’s Garden Humor: To boldly grow where no one has groan before.” Yes, you can tell from the tagline that this site is a lot of fun.

I have David’s permission to re-post his story, as long as I include the fact that he wrote it, he owns the copyright, you can see it on his website, and you can email him at dhobson@golden.net. (I was a bit concerned about posting his email address right out there in the open where all sorts of nasty software programs can find it and send him emails about missing fortunes, prescription drugs, and the fact that there are giant star-nosed moles in the storm drains under Boise—but he insisted.) After I went to all this trouble, the least you can do is read it and laugh. Oh, and the goat photo is all mine.

Outfoxing Fox Squirrels

fox-squirrel_blkforest_20100424_lah_3624If you feed them, they will come. Anyone who puts sunflower seeds into a birdfeeder sooner or later has to contend with squirrels. And if you grow a garden—well, squirrels like many of the same foods we do, plus flowers, tulip bulbs, and numerous other plants. The question isn’t whether or not you’ll have squirrels in your yard. You will. The question is, what are you going to do about them?

I used to really like squirrels. After all, they’re cute, with bright black eyes and fluffy tails. And they’re fun to watch as they chase one another up one tree and down the next. That was before I started feeding the birds. Within hours of hanging my first feeder, the squirrels had discovered it. (It took the birds two weeks.)
