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 blooms, deadhead or shear the plants back and fertilize them for renewed flowering in the fall.
