Field Trial Monitoring Results

Fair potential utility as an urban tree based on evaluation of 14 trees, healthy crown, 93% survival, slow growth rate. Herbivory found on majority of individuals and some signs of leaf dieback. Many plants had twisted or curling central leaders in nursery that resisted training.

Propagation Results

We got high rates of germination from 48-hour hot water soak and 24 hour aeration then greenhouse sowing in December. Seedlings are moderately fast growing with an unruly form.
