CAMPSIS

Vigorous climbers used for large-scale effects, quick summer screens. All bear radiant, orange-toned blossoms shaped like flaring trumpets in clusters at branch tips midsummer to fall. Glossy leaves are divided into 2 1/2-in., ovate leaflets. Stems have aerial rootlets that cling to wood, brick, stucco, and other surfaces. Unless pruned and tied to supporting surface, old plants can become top-heavy and pull away. Each dormant season, shorten some branches and thin others. Pinch back shoot tips in summer to keep plants bushy. Plants spread by suckering roots; pull any that appear. If older plants become unmanageable, cut to ground before spring growth begins and train a few strong new stems.
