Bougainvillea are characterized by vibrant colors on large petal-like bracts that surround the inconspicuous true flowers. Native to tropical South America, Bougainvillea are essentially scrambling shrubs that bloom most vigorously in hot, full sun. 'San Diego Red' is one of the best and most hardy cultivars. Large deep green leaves contrast well with the deep red bracts. When the bracts are fully open the color changes to hot magenta. Can be trained to tree form by staking and pruning. Vigorous grower to 20-30 feet long.
