The use of some growth retardants has been shown to result in plants that are less chill sensitive.
Member of the Gesneriaceae (gesneria family).
Native to Brazil.
Common relatives include African Violet, cape-primrose, Episcia and Achimenes.
Flowers are bell-shaped, velvety, with ruffled edges, in clusters held above foliage.
Leaves large, oval, somewhat fleshy and pubescent (hairy). There are so-called miniature types that some name S. pusilla while others still have them listed as S. speciosa. Regardless, the key fact is that they are smaller plants and some have longer flower stalks (peduncles) compared to their bigger cousins.
Flowers are not fragrant.
Chill sensitive, store and ship above 55 degrees F. This species does not ship that well so minimize this period to 3 days or less if possible.
Named for Wilhelm Sinning, gardener at the University of Bonn.
The specific epithet name “speciosa” means showy, good-looking.
May only look good under many commonly encountered interior conditions for 1 or 2 weeks.
Requires high light levels (>200 ft-c.) under interior conditions. Removing spent blooms will encourage new flowers to form.
Let plants rest (do not water) for about 2-4 months every year after which they again can be watered and fertilized for reflowering.
