Breakthrough free-flowering hybrid suffuses the border with a soothing aura of rich color. ‘Amistad’s vibrant deep-purple tubular flowers with glossy black calyx bloom are in non-stop blooming mode from early spring until frost. With compact, fuller habit, 14-16” tall plants dazzle in mixed containers or massed in the landscape; drought tolerant, heat tolerant. Cut back to encourage repeated bloom. A favorite destination for butterflies and hummingbirds. Full sun, part shade.
