Rocky Mountain natives
Best natives for Mountain gardens
Native plants are wise additions to gardens in the Rocky Mountain region. The eight species listed on this page are naturally suited to the cold-winter, short-summer climates in Colorado, Idaho, Montana, Utah, and Wyoming. Many of their flowers attract butterflies or hummingbirds― or both. Many of them thrive on rainfall alone. Plant them in spring; if you start with nursery-raised plants, remember that even drought-tolerant natives need to be watered during the dry season for a year or two until they’re established.
