A spectacular plant that is also known as giant hyssop or hummingbird mint. Agastache 'Astello Indigo' is a deciduous perennial. Blends well with other plants in the border - perfect in sunny borders and flowers all summer long. Delightful fragrance rather like anise and very rich in nectar so particularly loved by butterflies, bees and bumblebees. Hummingbird mint (Agastache) 'Astello Indigo' is easily grown and loves a nice sunny spot (free-draining, especially in the winter)! Most fertile soil will suffice.
