Thought I'd post an update. This one's growing well, the longest branches have extended around 3 feet or so and still going. It's quite a surprise how much it's grown. When I collected it there were basically no roots left on it and it was mostly dead. I have a feeling that it wouldn't be alive today if I left it in the woods.
I've found a even smaller one near where I dug this up. It's much healthier but still got a lot of deadwood. A probable candidate next season along with a very large old one that needs to be gotten rid of. It's so big I passed it up this past spring. It'd be a carving project for sure and an excuse to upgrade my dremel to a die grinder.
It's not an autumn olive but it's still a collected tree. I dug this honeysuckle which has extended it's branches just under 6 feet so far and still growing. It's currently my largest tree by far until I dug that big autumn olive. It'll be a carving project. I like the base and the way the trunks are but it's got zero taper in those trunks like all the honeysuckles seem to be and they don't heal wounds at all. Unfortunately you can't see the structure of it because they apparently sprout all over at the base when cut back hard.
