CAUCASIAN WALNUT, Pterocarya caucasica. 



Gardens. May. Its grand symmetrical proportions, fine foliage, and unique 



fruit make this one of the most beautiful of exotic trees. Being one of the 



first of deciduous trees to burst into leaf, it is apt to be damaged by late frosts, 



and should, therefore, be in a sheltered position. It may be propagated by 



layers, suckers, or seed.
