They are looking great! There is a big Sweetgum across the road from me that turns a brilliant orange every autumn. It is what is I assume the mother of many of the seedlings that grow like weeds around my property (though there’s a couple other less brilliantly colored so who knows). It’s so interesting to see the differences in them. There’s one I’ve let grow all year by my mailbox that has been uniformly purple for several weeks now. Another growing nearby has been pretty bland. Another in my landscaping has been hacked back over the course of years and I think will make an interesting tree which has yet to even turn at all. Trying to keep my eye out for nice colored volunteers to transplant and develop.
