Hello,

All the angelwing begonia pictures i have seen on the net show a plant around 18-24 inches tall, Single stemmed plant, packed with close growing leaves and a beautiful blooming flower. My angelwing begonia is about 4 feet tall has 4 main stems and has never bloomed. The plant itself is about two years old, perhapps more, i'll explain. I got this plant as a clipping, it was in my randmothers windowsill for about a year, in a mason jar of water, it had good root growth but it never grew taller or branched out untill i took it and planted it. once planted it took off like a rocket.

It has been planted for about two years now. each winter it drops all but a cpl leaves, but comes back each spring and summer with a good 12 inches of new bright green growth. ive heard that an angelwing begonia will get about 4 feet, drop its leave and have that stem die, and will grow another, but this one dosent seem to want to do that, it just keeps growing. It is in a south window, and i water it with a cpl Oz of water every 2-3 days.

I guess my questions are:

why is it getting so tall and not bushy
why hasnt it bloomed
can any chemicals make the folliage brighter, like phospherus does with some plants
whats any other general or detailed knowlege that could be helpfull
