Fraxinus (Ash) Notes

Oleaceae (olive family)

Most campus ashes provide pleasing fall color, but their low drought tolerance and greedy surface roots make them a questionable choice for continued widespread planting. Most have pinnately compound leaves. All ashes’ leaves are oppositely arranged (two to a node), as with other familiar members of the Oleaceae: olive, privet, and lilac. The leaf forms of most ash species is pinnately compound.
