The Mandevillas are tender in Phoenix and need careful planning to be used in landscaping as perennial plant. They are often used as patio plant or as annuals. They are great trellised in containers or in hanging baskets.

Cultural Practices:
The Mandevillas have tubers similar to a dahlia, and do not like overwatering in winter. They like a rich, well drained, sandy soil. Prune as needed in summer or winter. Fertilize every 2 weeks with balanced fertilizer, or a fertilizer rich in phosphorus (10-20-10 for instance).

The Red Riding Hood blooms at the end of April in Phoenix. The fragrant 4 inches wide flowers last 4 to 5 days, and turn somewhat darker at the end of the first day.

Fruiting Habits:

Single node hardwood cuttings sprinkled with rooting hormone should start growing in 4 weeks.
