All of those amazing flowers people have been showing of late need to start from somehwere.
How about some Begonia tubers just starting to shoot?
This is a tender perennial that most people throw away at the end of the summer.
They are sensitive to cold and rot easily. The reward is spectacular when they do flower.
These large tubers, hidden under the soil, are about 40 years old. I took them off my father's hands a few years ago. He didn't want to let them go but he wasn't in a position to care for them. So, I have been under pressure to keep them alive over winter. So far so good. He'd be mortified if they didn't survive.
They are starting a bit late this season because I had overwintered them in the garage and they got lost amongst some other stuff.
