Flowers in March-April

Cultivation: Easy to to care and flower. No absolute schedule can be given for watering as  various factors (Soil mixture, containers, drainage, temperature, size of plant) influence water use, so  - as a general rule - the soil should be thoroughly wetted at each watering during the active growing season (spring and summer), water when the top 1,5- 2 cm of soil feels dry to the finger. Do not soak the soil during the dormant period. Be careful, excessive watering can make root and/or stem to rots. Make sure there is good air circulation between plants. Good drainage is essential along good moisture retention properties and adequate nutrients availability. Require bright sunlight to grow well. Dormant plants do best at temperatures from 5-10°C (but will tolerate -5° for short periods). The cooler temperatures develop sturdier plants and encourage the formation of flower buds.

Propagation: By offsets which often are found growing around the base of the plant,  Remove the basal offset (if available) in spring or summer and let the cuttings dry for a few days before inserting in compost or (usually) by seed.
