Light. Full to part sun gives the best growth and flowers. In shade it flowers poorly.
Water. Water while it establishes. It is drought tolerant but appreciates some irrigation during long dry spells.
Soil and feeding. Any soil is suitable, including alkaline soil. Light feedings through the year with a flowering-shrub fertilizer such as Bloom Special promote growth and blooms.
Size. Grows to about 8 ft as a loose, semi-open shrub, usually 4–7 ft wide. Space plants 4–5 ft apart for a flowering hedge.
Pruning. Stems often grow several feet without branching. Pinch new shoots to make it denser and add more flowering tips.
Problems to watch. Mites can infest the leaves. Witches' broom can deform the plant.
Good to know. Unlike vining allamandas, it does not climb. Swallowtails and sulfurs visit the flowers. Clip off the prickly seed pods to limit seedlings.
