[ Chenille Prickly Pear (Opuntia aciculata) | Posted on June 20, 2017 ] Opuntia aciculata is separate from O. strigil, O. engelmannii, or O. lindheimeri, though it has been conflated with these species. A long-spined form was invalidly named O. strigil flexospina, but it is really just a minor spine variant of O. aciculata. Plants may reach 3 1/2-ft tall and spread to over 4- to 6-ft across, but they are often smaller. |
