Cultivation Details
Peniocereus greggii is native to arid and semi-arid regions of southwestern N. America. It can tolerate occasional, short-lived light frosts, but the stems are susceptible to freezing, though they are able to regrow rapidly from the large tuberous root[1]. In cultivation, Cactus plants generally will not succeed in moist climates. They usually require a sunny position in a well-drained, circumneutral soil and to be kept more or less dry in the dormant season[2]. The flowers are spectacularly fragrant, opening shortly after sunset and visited by pollinating hawk moths (Sphingidae), and quickly wilting after sunrise[1991 However, populations of this moth are decreasing due to the heavy use of pesticides locally[3].
