Balcony's Garden
Gloxinia
I have two plants of Gloxinia that my wife bought at the supermarket where she works. They were reduced & only one had a few flowers. Up until a few days ago I had no idea what colour it would turn out to be!
They are now flowering & have very many buds on them, so I look forward to seeing them bloom for at least six weeks which is as about as long as you can expect them to flower according to this website I found.

I discovered from the webpage that they can be reproduced by leaf cutting just like African Violets, of which I have quite a few & am constantly propagating, either by leaf cutting or by division. I shall have a go, if they are as easy as African Violets I shall have dozens in a couple of years time!
Update 2015:
These plants died some years ago & I no longer have any Gloxinias.
