It grows fast in spurts when water is abundant, and sometimes reaches more than 25 m in height. Its trunk is bottle-shaped, generally bulging in its lower third, measuring up to 2 m in girth. It is studded with thick conical prickles which serve to store water for dry times. In younger trees, the trunk is green due to its high chlorophyll content, which makes it capable of performing photosynthesis when leaves are absent; with age it turns to gray. The branches tend to be horizontal and are also covered with prickles. The leaves are composed of five to seven long leaflets.

Their nectar is known to attract insects such as monarch butterflies, which per
