Indoors and in a pot, expect 5-10 cm tall, spreading to 20 cm in clumps. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Its feeding profile backs this up: feed once in spring with a half-strength, low-nitrogen cactus fertiliser. a second light feed in early summer is optional. do not feed in autumn or winter.
