The plant grows from a large, tuberous rootstock that can sometimes reach 60cm. in diameter and weigh up to 50 kilos, though it is more commonly 15 - 20cm long by 5 - 8cm in diameter[

The plant is harvested from the wild for local use as a food and medicine. It is often grown as an ornamental.
Peniocereus greggii is threatened by development from roads, power lines, pipelines, and windmill farms. There is also probably some illegal collection for horticulture. Even though some populations have been extirpated, the plant occurs in a wide area and is widely scattered and very difficult to find, which confers the species some protection. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2017)[
