Description

Grusonia pulchella Online Guide to the positive identification of Members of the

Grusonia pulchella differs from other North American opuntioid cacti in having a geophytic habit, where above-ground growth dies back to the crown in adverse conditions, and resprouts under more favorable conditions. Authors have described the underground storage structure as a "tuberous root" or true tuber. The above-ground stems are variable, being cylindrical to globular. The areoles bear flexible yellow spines and white wool. Overall, the above-ground growth can often form a cushion-plant habit. The flowers are bright magenta, and the fruits are dehiscent. The seeds are unique, with a groove running along the hilar surface.
