I bought a small 'Jade Butterfly' last spring and planted it in my front yard. The plant was about 2 ft tall and had a single leader. Unfortunately, Mr deer came by and pretty much decapitated the ginkgo and what was left was about 6 inches tall. This year, the ginkgo grew 3 nice branches with each over a foot tall. Do you think the new branches are 'Jade Butterfly' or just whatever the root stock is? I didn't think 'Jade Butterfly' would grow this fast. Thx.
