While often labeled a summer grower, this species follows a more opportunistic, bimodal cycle governed by the Mexican monsoon. It experiences a primary growth spurt in late spring to early summer, often followed by a brief semi-dormancy during the extreme heat of mid-summer (July). A second, vigorous growth and flowering phase occurs in late summer and autumn (August to October). It enters a deep dormancy in winter and should be kept completely dry to protect its large, fleshy taproot from rot.
