One tree of this tropical genus grows in the lawn at the front left of Harmony House on Lomita Drive. The palmately compound leaves contain five leaflets. Clusters of showy trumpet-shaped blooms, purple-pink with yellow throats, appear in May.

Long identified as Tabebuia impetiginosa (and then Handroanthus impetiginosus) in California, its toothed leaflet margins easily distinguish it from the smooth margins of that much rarer species. Ours may be the only specimen in this area. It is much more commonly grown in southern California.
