- A few species such as S.aggregata and S.caranggolensis have scented foliage.
Some are an evergreen perennial, others have a winter dormancy, and all d\require a warm climate to grow well outdoors, think tropical to sub tropical. However they perform very well when grown as an indoor plant.
Basic Sinningia Care
Bright filtered light is essential, not hot direct sun. A humus rich well drained soil is ideal and plants should be kept moist in the growing season.
Planting depth depends on the variety and your climate. Tubers can be partly exposed, however if your climate zone is subject to freezes, they can suffer terminal damage.
Propagation is from seed, leaf stalk cuttings, tuber cuttings and also0 tissue culture. Cuttings are difficult.
