Agastache ‘Summer Sky’

Hummingbird Mint

USDA Zone: 8-9

Plant number: 1.025.080

One of several recent hybrid selections, this is a real workhorse in the garden, flowering non-stop from midsummer well into the fall. It forms a low, bushy mound bearing dark upright spikes of glowing violet-blue flowers that attract both hummingbirds and butterflies. Great in containers or in the mixed border. Must have excellent drainage, particularly during winter otherwise plants may rot and not survive. Quite possibly hardy to Zone 7 or colder in dry winter regions. A 2009 introduction from Terra Nova Nurseries of Oregon, one of several colourful hybrids they have been selecting. USPP#20952: unlicensed propagation prohibited. Registered with COPF.
