XERIC COLD HARDY ROSES

This is an article that ran in 2004 in either 'Colorado Gardener' or 'The Rocky Mountain News'....I forget which. Except for the reference to the local fertilizer 'Mile High Rose Feed', the contents of this article should be useful to anyone wishing to grow roses reliably and easily in a cold dry climate in a region with alkaline soils like Colorado.

"DROUGHT DEFYING ROSES
  
Have you ever pulled into your driveway and felt utterly underwhelmed by the bland "mustache" of boring junipers strangling the front of your home? Do you feel hemmed in by the insipid privets that form passionless parentheses constricting your property like cheap bookends? Is your shrubbery in general about as exciting as reruns of "Who Wants to Marry a Millionaire" ? Do you lurch instinctively for the loppers and shovel to happily render a radical juniperectomy, only to feel paralyzed by not knowing of alternative INTERESTING replacement shrubs that are are also drought-resistant, winter-proof and low maintenance?
Believe it or not, some beautiful and TOUGH varieties of richly-colored and deeply fragrant Shrub Roses increasingly available in Colorado can artfully fill the void created by joyously tearing out colorless, scentless, soul-less overgrown junipers and privets. And unlike the the frail, finicky, short-lived grafted "garden roses" that convince so many folks they have "brown thumbs", these drought-defying Shrub Roses, when grown on their OWN ROOTS, mature into beautiful flowering landscape shrubs that need no chemical coddling, and little watering once established.

Let’s face it; few of us lovingly admire a prickly blob of junipers...but a privacy hedge that bears hundreds of richly scented pink, red, white or yellow roses each summer, plus perfumes the yard while providing luscious Victorian style bouquets for the dinner table, fragrant petals for potpourris, and a bonus of bright red hips for winter color and attracting wild birds, now THAT would be awesome and waterwise!

While many different kinds of near-xeric, cold hardy yet lusciously fragrant varieties may be lumped under the catch-all label of "Shrub Roses", those listed below share the same minimal care needs: one optional annual pruning in early to mid-July after last petal drop, a 6"-8" deep mulch of tree grindings (usually free from a tree trimming service) to keep their root zone moist, 1 or 2 deep waterings per month in summer, and one annual feeding of organic nutrients in April (try 2-4 cups of ‘Mile High Rose Feed’ per bush). All are remarkably resistant to disease, insects, drought and winter freeze damage, and thankfully are sold by more and more Colorado nurseries.

Beware: those offered for sale in some quite famous mail-order catalogs are almost always GRAFTED onto a rootstock often grown in mild southern regions near the Mexican border; avoid these wimpy wannabes! These grafted, namby-pamby impostors are rarely vigorous or long-lived despite the alluring pictures in those glossy catalogs; bu only OWN ROOT Shrub Roses if you want the hassle-free toughness of junipers and privets PLUS wonderfully fragrant roses to plunge your nose into......breathe deep!....life is good!

Seek out juniper replacements from this list of fragrant Shrub Roses known to thrive on the plains of Colorado with minimal care; those followed by an (R) can bless your landscape with a Repeat flush of blooms in late summer and early fall. Remember that Own-Root roses are generally small when when purchased...a turn-of-the-century saying about own-root roses’ slow initial growth rate is: "First year they sleep, second year they creep, third year they LEAP!". Unlike grafted roses, they initially expend their energy forming an admirable root system THEN get big, living for many decades. That is why so many very old ones are seen thriving in old cemeteries and homes and abandoned farmsteads.....they are true survivors in our harsh dry climate. And the sensual symphony of their heady fragrances and broad range of colors can create a water-wise annual jolt of joy where monochromatic junipers once induced a near-coma with their numbing sameness.

So if you’ve ever felt you had to choose between keeping big boring bushes or yanking them only to have a starkly empty landscape to conserve water, just remember Mr. Spock’s truism: "There is always a third alternative". And own-root Shrub Roses are that alternative, one deserving the long-overdue attention of our eyes, noses, minds and souls.So go ahead....DO that juniperectomy!....here’s the delicious menu you can select from:
