Agastache Blue Boa Ground Cover

Agastache Blue Boa (Giant Hyssop, Korean Mint)

A wonderful, compact new variety with large numbers of deep violet-blue flower spikes from June until October, light green aromatic foliage that smells of liquorice when bruised. The leaves are edible and can be used to liven up salads or infused to make a Hyssop tea. Agastache flowers are very popular with bees and butterflies, later in the season the seedheads are very popular with birds.

As a rough guide planting Agastache Blue Boa as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage and 9-12 will make a weed supressing carpet very quickly.
