Curses upon the Bougainvillea! in Landscaping and Lawn Care Posted July 22, 2009 The house we've just moved into has a lot of overgrown landscaping, including an indeterminate number of bougainvillea bushes. One is blooming; the others just lurk, waiting to attack you with their horrible thorns. We keep cutting and cutting and they grow back overnight. Like evil alien spawn.The funny thing is, I always wanted to have bougainvillea in my garden because I thought they were so pretty. Little did I know how evil they actually are!
