Agastache Blackadder (Giant Hyssop, Korean Mint)
Gorgeous smokey violet flower spires from June right through until October, held above aromatic fresh green leaves. Not only is this plant a brilliant addition to the herbaceous border, its a great wildlife plant, the flowers are adored by bees and butterflies and later on the seedheads will provide a welcome feast for the birds. Looks great with Ornamental grasses, or in a mediterranean themed garden.
As a rough guide planting Agastache Blackadder 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.
