The stem take a nice dark reddish tinge in full
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
(8°C 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 can’t 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.
