A giant African Violet!

Wow that is big but stunning yes would love to see another photo when in full bloom . Not the African Violet we know here.

Streptocarpus, right? I used to have a lot of those outside growing when I lived in Hayward. They love Haywards' nice mild subtropical climate! :>)) I know it's a close relative to African Violets.

This kind Andy they only like watering from the bottom.

You can actually water the leaves. The water must be around 90ºF to water the whole plant. I used water my mom's African Violets for her I would let the warm water run over the plants. If the water is cool or cold it will spot the leaves very badly.

Every time I ve watered from the top which goes over the leaves they have died.

No,this is a Chirita. Its just something I spotted in Loggee's catalogue around 2002 or so. I did think it was a small plant. I had kept it in a small pot until one day my wife planted it in that big pot. To my surprise- it GREW..BIG.
Mostly blooms in fall.

Oh wow! That's a beautiful plant! I'm not familiar with this genus. It does look a lot like an African Violet.
