(This plant comes in a 3.5 inch pot. You will receive a very similar plant to the one in the picture. It may or may not be blooming at the time of your purchase. The plant is shipped in its pot to prevent any damage to the roots).
Flower: bi-colored with magenta, rose to the violet petal tips and pinkish-white.
Blooming season: Blooms late summer.
Cultivation and propagation: It is a summer-growing species of relatively easy cultivation. It is quite susceptible to over-watering if kept in a non ventilated place.
Growth rate: Slow-growing.
Exposure: It is suited for sunny-brightly exposure but can tolerate light shade. However, it will do its best only with lots of sun and become stressed with inadequate light which could result in poor growth and unnatural shape. It has a good heat tolerance.
Watering: Water sparingly and keep it completely dry during winter. Mature individuals easily rot and die especially after transplanting so be extremely cautious with watering. Keep dry in winter or when night temperatures remain below 10° C. Water it less than average if in bigger pots.
Special needs: Provide very good ventilation.
Hardiness: It likes warmth (recommended minimum winter temperature 5° C). But plants kept perfectly dry can easily survive to winter night temperatures below 0° C.
