Variegated Joseph's Coat (Opuntia monacantha f. monstruosa variegata): Prickly pear cactus with interesting green and creamy white variegation, sometimes flushed with pink. The pad-like stems of this cactus create offshoots and stack up if given room to grow. This plant can take a bit more frequent water than most cacti, but does need full sun and excellent drainage to thrive.
