Answer: Bougainvillea looks fantastic cascading down a hill and the best choices are those that naturally sprawl rather than climb. The lowest growing bougainvilleas include Crimson Jewel, La Jolla, Oo-La-La and Hawaii. Rosenka tends to have a more upright growth habit, but can be pruned to keep it low. I'd choose one of the other cultivars for your purpose. Enjoy!
