Cultivation: It is a summer grower species that offers no cultivation difficulties.  Water regularly in summer (but do not overwater ) Keep this plant almost dry in winter at a minimum temperature of 0C, prefer relatively rich substrate and  low pH  compost (if possible not limestone) otherwise growth will stop altogether. Feed with a high potassium fertilizer in summer. It is quite frost resistant if kept dry (hardy to -5 C)
Sun Exposure: Light shade. It may
tolerate bright situations  but is
likely to suffer from sun scorch or stunted growth if over exposed to direct sunlight during the hottest part of the day in summer. This plant needs plenty of space for its roots, repotting should be done every other year or when the it has outgrown its pot. This species is particularly easy and accommodating, seldom suffer of cryptogamic diseases.
Propagation: Direct sow after last frost. (seldom produces offsets). Seed Collecting: Permit fruit to ripen.  Fruit must be significantly overripe before harvesting seed; clean and dry seeds.
