Agastache​

Agastache is a genus in the family Lamiaceae, with fragrant leaves  and long spikes of small flowers. There are about 22 species in the genus, all native to N-America, apart from one, which is native to E-Asia. They are popular garden plants in warmer climates as they attract butterflies and humming birds and a great variety of garden cultivars are available. They have little value in Icelandic gardens and are fairly tender.
