I live on Puget Sound - zone 8b. I have sevearal fuschia "magellanica's" growing in my yard. They die back most winters and grow to about 6ft tall every season, just like Harry describes. I have dug up some root chunks and potted them on several occasions. The only problem I have encountered is that they are surprisingly cold fragile in pots. Else it seems to go pretty much as Harry shows, though I have yet to achieve anything like Harry did. Nevertheless, I had enough fun to get hooked on bonsai and enough experience to move on to real trees.
Just buy one (or more) and get on with having fun.
I just started a couple of starts again. Thanks for reminding me!
