Special Offer: Buy any 6 perennial plants for £16.99! You save £6.71
Less of a poisoned chalice than its name may suggest, the Black Adder Agastache forms in upright clumps and displays reflectively glossed fragrant foliage around dense spikes of purple-blue flowers. An ideal solution for adding density to the rear of borders, the Black Adder adds beauty to your garden from midsummer to late autumn and will attract bees and butterflies in droves.
