Allamanda


                            Allamanda

Allamanda includes approximately and species of shrubs and shrubby climbers from tropical America. Several are among the most com-monly cultivated summer- bloom-ing plants. Cultivar names, of dubi-ous merit, vary from country to country. Allamandas thrive in moist, coastal regions but are only slightly salt tolerant at best. Some are night fragrant. Prune them in early spring to keep shrubby or tie to a support for climbing. Plant in deep, humus-rich soil. Cool night temperatures, lack of water in summer, or spider mite infestation in-duce leaf loss and sparse appear-ance. Propagate from cuttings of better selections. Allamandas are superb when landscaped with com- plementary dark purple foliage plants.
