Here is a favorite arboretum tree that never fails to grab the attention of my siblings and me on our autumn visits. Aptly called the blue sausage tree, you can really see the seed pods to advantage when the leaves turn yellow in the fall.
I have one seedling left after starting these about five years ago. I think sister Cate has one, as well.
My little tree is probably very pot bound, so future plans will be to pot it on into a clay/ornamental pot and start trimming and pinching it to get more than just a stick shape.
