CHARLIE'S PLANT TO PONDER: Allamanda

Allamanda (A. cathartica) is a sprawling, vining plant with yellow, trumpet-shaped blossoms throughout the warm season. The flowers of specimens grown in full sun on rich, mulched sites can be 5 inches across. Train this vine on a trellis or chain link fence, or let it clamber up small trees and large shrubs. Propagate with cuttings.
