It is not common in collections, in part a result of its restricted range and scarcity in its habitat. In more recent years, sufficient seed has become available to secure the species in cultivation. Plants raised from seed prove that this cycad has a remarkably rapid growth rate in cultivation. It is not unusual for seedlings to produce several growth cycles per year, and plants 2 - 3 years old can produce three or more sets of leaves each year. Remarkable also is this cycad's tolerance to cold weather. It can withstand temperatures as low as -9.5 C (15 F). Cultivated plants have proven that it will grow well in tropical and temperate climates.
