Same here.
After we sold our last home we lived in a rental until we found this house. I was taking cuttings of my begonias each time we moved and some made it some did not. I am slowly building up the collection again.
This is one called 'Gray Feather' that I found at our local ACE hardware in December.
It was just a few cuttings stuck in a pot. Boy has it grown, that is an 8" pot. I can't wait to see what it does when I put it outside in the next week or two. Trying to decide if I should separate the plants, my thoughts are to leave it together and take cuttings as it grows. What do you think?
