Sinningia : Greenhouse Plants
W – warm, minimum of 13°C (55°F)
This is a difficult group of plants to talk about because so many of them are now referred to by other names. Sinningia cardinalis will be found under Gesneria macrantha and S. speciosa are dealt with under the. Thus we are left with the miniature Sinningias which are very attractive and would appeal to collectors of miniature African Violets which are in the same family. S. pusilla is one of the parents of many of the hybrids available. Leaves are only 1.2 cm (1/2 in) across. The trumpet-shaped flowers are a delicate violet colour and held above the leaves by 2.5-cm (1-in) long stalks. Providing the temperature is constantly warm this species and its varieties should flower almost continuously. S. ‘Dollbaby’ has lilac-blue flowers and S. ‘Pink Petite’ is shell-pink. The important point to remember is not to Over-water and never splash the plants with water. Some are so small it is best to stand them on upturned pots as they are likely to be swamped with water before you realise they are there. Good shading will be required during late spring and summer. They are easiest to obtain by seed which is very fine and should be sown on the surface of a peat and placed at 21°C (70°F) in a light place, where germination should take place within three weeks.
