To choose permanent shrubs and trees, plow through localized information and heed the advice of native gardeners. Broadleaf evergreens, such as mountain laurel and rhododendron, tend not to grow well here. The alkaline soil, low humidity, dry winds and intense sunlight hinder their growth. Better shrub choices include Oregon grape holly, juniper, potentilla, viburnum, lilac, ninebark and others. Tree choices also must be made carefully.
Snow is great for skiers but disastrous to tree limbs.
Because of Colorado's tendency for early or late wet snows, tree limbs often break from snow loading. Plant trees that are less brittle, but be patient, as these types take longer to mature. Recommended trees include Norway maple, linden, swamp white oak, honeylocust and green ash. For small trees, try Russian hawthorn, Amur maple, Shubert cherry, Callery pear, Japanese tree lilac and serviceberry. The same is true of plants.
