Snapdragon 'Black Prince'

Antirrhinum majus nanum
Gorgeous deep crimson flower spikes bloom above glossy green foliage that darkens to bronze-purple in cool weather. This heirloom variety has the classic flower shape that gives it its name, for they yawn wide when the base of the floret is gently pinched. 'Black Prince' is a shorter variety that needs no staking-sending up its spires of smoldering velvets at the edge of cottage gardens to mid-border.

Compact snapdragon selections are a great addition to summer gardens, whether placed mid-border, at garden edges, or in containers. They add a striking vertical element and are easy to manage. These plants are excellent for cutting, blooming throughout the summer in areas where the nights are cool, and in late spring and fall in hotter regions. To encourage bushy growth and a profusion of blooms, pinch the plants when setting them out. Native pollinators, such as bumblebees, are fond of snapdragons, and their weight can open the hinged flower to access the rich nectar and pollen. The bees carry this golden dusting to the next blossom, fertilizing the plant. After the first flush of bloom, deadhead, removing the spikes with developing seeds down to vegetative branching, or shear the plants to 6",and fertilize the trimmed plants for renewed flowering until late fall.
