Denomination: Poplar Crow's Nest
Clone Name: Crow's Nest
Scientific Name: (Populus deltoides x P. nigra) x P. nigra
Description: Female clone. Numerous side branches have steep branching angle, resulting in a narrower crown. Primarily used for horticultural shelterbelts. Side branches are light, require little or no side trimming. Also used as soil conservation tree in east coast regions as it is relatively drought tolerant.
Leaf Characteristics: Smaller and rounder than P. x euramericana hybrids. Leaf base tapers towards leaf tip. New leaves flush reddish-bronze in mid-late September in Manawatu, maturing to dark green on the upper surface and light green below, with a red midrib.
Site Limitations: Low-moderate rust and anthracnose resistance, is palatable to possums. Susceptible to Marssonina in cold/wet during the growing period.
