(Syn: Discocactus hartmanii ssp. magnimammus)
CACTUSPEDIA       

 


Discocactus magnimammus HU324 Near Caracol, Mato Grosso do Sul, Brazil 280m
The stem take a nice dark reddish tinge in full sun.

Cultivation: Collectors consider this cactus genus from South America to be rarities as they are not the easiest plant to keep happy. it is rather difficult to grow and frost tender, should be kept at above 15 C if grown on its own roots (8C if grafted) need full sun or afternoon shade. Young seedlings are generally grafted because they are slow growing and very rot prone when kept on their own roots and though they cant endure long stretches of total dryness, too much water will rot them, as their weak root systems tend to be inefficient at sucking up water from wet soil. They generally resent being repotted and can take a long time to establish.Propagation: Seed.
