This rare cultivar is
slow growing and tricky to cultivate.
It will form quite
several offsets, if given time and grown properly. Water regularly from
spring through fall, but do not over-water (rot prone).
Let soil become
moderately dry between thorough waterings.
In winter, keep dry or water
only enough to keep the plants from shriveling. Use pot with good
drainage and a very porous potting media.

should be fertilized once each spring
with a high potassium
It is quite frost resistant if kept dry, hardy as low as -4°
C. Outside full sun
or afternoon shade, inside needs bright light, and some direct sun, but
