'Black Adder' is a stunning Agastache variety that produces tubular flowers of a smoky lilac that open from dark purple buds in July through to September. The pretty flowers sit above scented foliage in a bushy compact habit so we recommend planting in areas where they will be enjoyed such as the front of the border, in containers near doors and on patios. 'Black Adder' also make wonderful cut flower displays where these unique blooms will add interest to bouquets within the home. A perfect choice for encouraging wildlife into the garden where butterflies and bees are attracted to the area. A hardy and reliable perennial, they will thrive in well-drained, fertile soil where they will reach an eventual height of 75cm. 9cm pot plants supplied.
