The production of spines in the cactus is from structures known as areoles. These specialized structures can produce flowers as it is multi-petaled and tubular type.

Cactus plans have a long dormancy period and a short growing season. The reaction of the plant to rainfall is quick as the root system is shallow.

The stems of the plant are fluted or ribbed which helps in quick contraction and expansion for water absorption.
