I have a few begonias in my garden, they are leaf-, tuberous- and cane-begonias.
I don't know much about how to care for these plants but thanks to the suitable growing conditions, they grow well and now bloom for me.
This is a local variety of cane begonia. This plant can grow very tall in my region.
This is a rex begonia. It's the second one I bought. The first one rotted on me maybe because I fussed too much with it. This time, I let it be and it is growing beautifully.
I bought this one in one of my trip down the Mekong delta. It looked pitiful then. I thought it would be picky but to my surprise, it just grows by itself, ie. I didn't do much to it except re-potting it to my mix when I first bought.
And this cane begonia is grown from a small cutting given me by a friend from the GCS (Greenculturesingapore) forum.
I'm on the look out for more varieties, but as always, it's not easy here.
