PLACEMENT & CULTIVATION
Columbine 'Denver Gold' attracts butterflies, bees, and hummingbirds; its spring bloom making it valuable as an early-season nectar source. It is also deer and rabbit resistant and grows equally happily in the dappled sun of woodland edges or in sunny gardens. This species is native to the Southwest and is vigorous and long-lived, and spreads agreeably from self-sowing, with new seedlings true to type. Cut flower stalks after bloom to encourage a rebloom and trim foliage for fresh new growth if desired. Perennials bulk up roots and foliage in their first year of growth, blooming more abundantly starting the second year. Caution: contains some toxic elements especially in the roots and foliage.
