Sinningia warmingii is usually a tall plant, with the flowers being borne at the top of the stem.  It is easy to grow as long as it gets enough water and sunlight.

Calyx

The distinctive red calyxes can be seen in this picture.

Hybridization

Ruth Coulson has crossed this species with S. carangolensis.  She sent me seed, from which I got an abundance of seedlings, some of which I distributed to unsuspecting members of the local Gesneriad Society chapters.

As far as I know, this is the only cross which has been done with S. warmingii.




Horticultural requirements

Despite its apparent need for lots of light, Sinningia warmingii is something of a watering wimp.  At least when growing in pots, my plants tend to wilt as soon as the soil dries out just a little bit, and the leaves burn when the weather is hot.  Sinningia leucotricha looks delicate, but it is actually lots tougher than S. warmingii.

See the drought-tolerance comparison table.

Going underground

On 7 December 2006, I was preparing to move a pot of S. warmingii into its winter quarters for a sleep of several months when I noticed green shoots around the rim of the pot.  When I knocked the plant out of the pot, this is what I saw.

Rhizomes!  Not only that, frustrated rhizomes.  They had been trying to expand their horizons, only to meet the impenetrable barrier of the plastic pot.  So around they went until finally giving up and coming to the surface.
