Fringetree is a member of the olive family, but now probably would like a divorce.  Recently, the scourge of emerald ash borer has spread to this species.  EAB has killed a gazillion ash trees.  The females lay their eggs on a wide range of tree species.  The larvae die on all but ash, and now fringetree.  Experimental attempts to grow them on elm, hickory, walnut, and lilac have failed.  We can dream that ash and fringetree will be the limit here, and that biological controls now being introduced will work without messing anything else up.  So far, the main problem is that the controls don't work well on an ongoing basis in northern states because of low winter survival.
