The plant, at least the spineless but with glochids variety, resembles a larger, more erect version of opuntia humifusa. It is one of the hardier opuntias, usually growing in zones where Agave americana does.
What is remarkable is that it's fruit is palatable, having its main taste similar to beetroot/wine and texture kiwi. Fruit is always red, and about the size of a small pear or a large medlar. Yellow flowers, late spring.
