about astello indigo

Agastache hybrid 'Astello Indigo' is highly versatile and can be grown for perennial and annual borders, containers and patio pots, alone or in mixed combinations. The uniformity of this variety creates a beautiful sight when planted 'en masse' in borders or landscape plantings. Ideal for Northern European-type climates - performed well in trials in warmer climates, but is at its best in more temperate conditions.

in the records

Also known as hyssop or hummingbird mint, these plants are famous for attracting pollinators and hummingbirds. In 2012 Astello ‘Indigo’ won the Fleuroselect Gold Medal for it’s outstanding beauty and breeding.
