Monkshood is wonderful old-fashioned perennials, perfectly suited for border plantings. This selection of flowers from late summer to early fall features striking upright spikes of lavender-blue flowers. Each flower is shaped like a hood, thus the common name. The deeply cut leaves are glossy and dark green. Strong stems so should not require staking. Plants prefer a site that will not dry out in summer, away from thirsty tree roots. In hot summer areas, this will need protection from the afternoon sun. CAUTION: toxic if eaten/harmful via skin.
