This cactus is very interesting for cultivation for several reasons. Firstly, this cactus grows in mountains and in winter it is covered by snopw during several months. Few cacti in the world can do that. For this same reason, it is very important to carry out cold stratification of the seeds. Secondly, this cactus is edible and has very big fruits, compared to its size. Thirdly, it grows fast and begins fruiting just in a few years. You should consider that most edible cacti may take up to 10 years before starting to produce fruits. This one is fast.
