Distribution

 southern USA to south Mexico
warm arid areas

Growth period

this genus is sensitive to too much moisture, therefor sparsely and carefully watering keep the root neck dry
during the flowering period slightly more watering, if not the buds could dry up
during mid summer give a short dry period at a sunny location
this genus is very recommended for a cultivation in a cold frame or a very bright greenhouse

Winter period

 dry and bright at 4–12°C (39–53°F)

Soil-mixture

 minerally and very permeable to water, keep the root neck dry
addition of quartz gravel and pumice is recommendable
