Members of the agastache genus, hyssops are known for their brightly colored flowers and for attracting hummingbirds and butterflies to the garden. They are generally hardy to USDA zone 5 Front Range gardens and many can be grown as annuals in containers elsewhere. Sunset hyssop grows to two feet in height and bears orange flowers with lavender buds. Brushing against the plant's narrow leaves releases a pleasant, root beer-like aroma. Plant them in full sun to partial shade.
Hummingbird mint smells like bubblegum.
It reaches two feet in height and three feet in width in full sun. Other hyssops are being introduced to Colorado and tested for their cold tolerance. Plant hyssop in late spring to early summer.
