Sinningia sellovii growing in a community garden plot in Washington DC. For scale, the pots around the tuber, which is planted in the ground, are sized between 2 and 4 inches.
The new growths are much sturdier (shorter internode length, greener, stubbier leaves) than the single stem that came on the tuber when it was planted. The original stem flopped onto the ground, it bloomed (see here), and it's now growing leaves at the tip--perhaps even forming a new tuber!
Is there anyone else growing S. sellovii in their yard or garden plots? How do yours fare?
