One of my favorite autumn colorations in trees has to be the claret ash (Fraxinus Raywood). As the weather starts to get a little nippy, the green foliage starts to turn to a luscious deep burgundy color (or claret – whichever suits your fancy). It’s a lovely specimen of a tree, doesn’t have a large extensive spreading canopy like your elms but is a pretty feature tree all the same. The dense foliage gives good shade in summer. The leaves are pointed and elongated. It can grow up to 60′ so give it plenty of space.
