More Information
Botanical PronunciationKAMP-sis RAH-di-kanz
LoreDiscovered in 1998 by Monrovia Growers' Propagation Manager Andrew Proud, growing wild on Balboa Island, California. Large clusters of tubular shaped flowers in velvety red with hues of orange remind one of a tropical sunset. This easy-to-grow selection of the native southeast species is also very attractive to hummingbirds.
Average Size at MaturityVigorous, clinging stems quickly reach 30 ft. or longer.
Bloom TimeLate Spring through Fall
Design IdeasA great fast growing flowering vine for cloaking open shade arbors quickly. Snake it up posts or columns to overhead trellage at gateways and entries. Will sprawl up large bare walls and across the roof to bloom in the heat. Good coverage for masking old or unattractive fences and outbuildings from view. Drape over walls or let it cascade off retaining walls. Add to wildlife friendly settings for increased hummingbird draw.
