Propagation of Plains Prickly Pear:Seed - sow early spring in a very well-drained compost in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first two winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Give the plants some protection from winter wet. Make sure you have some reserve plants in case those outdoors do not overwinter. Cuttings of leaf pads at any time in the growing season. Remove a pad from the plant and then leave it in a dry sunny place for a couple of days to ensure that the base is thoroughly dry and has begun to callous. Pot up into a sandy compost. Very easy, rooting quickly.
Cultivation of the herb:Dry prairies, sand hills and rocks.
Known hazards of Opuntia polyacantha:The plant has numerous minutely barbed glochids (hairs) that are easily dislodged when the plant is touched and they then become stuck to the skin where they are difficult to see and remove. They can cause considerable discomfort.
