So it's an older Alder called an Elder Alder. An old tree. I get it.
I'd have fun with the potential....could end up unusual and very attractive. Give it some effort and time.
Hehe no.. but this is the crossed wires that got this dug up
Its now been ID`d as not Alder (Alnus), but Elder (sambucus). After looking into it the ID is spot on, and they are not good subjects for lots of reasons..
But its here now, in a pot, so will continue to care for and take it on the ride
Even if it all ends up as some one else asking in years to come "Elder bonsai?".. first hand knowledge..
