Bougainvillea Plant. However, bougainvilleas thrive in hardiness zones 9 and above, so if temperatures drop below 30 degrees, we recommend bringing your potted plant inside. To avoid root rot, do not plant them in soil with high levels of peat moss.
Keep bougainvillea on a slightly drier side for abundant blooms. Bougainvillea is a relatively hardy plant, able to withstand a range of temperatures, from tropical highs of 80 degrees fahrenheit and above, all the way down to 40 degrees fahrenheit. Bougainvillea is an incredible addition to any landscape.
