Field Trial Monitoring Results
Fair potential utility as an urban tree based on evaluation of 3 trees, healthy crown, 100% survival, fast growth rate. No signs of pests or diseases found. The hooked spines on this species have made it difficult to manage.
Propagation Results
We had decent germination with hot water scarification and sowing in a warm greenhouse in January. Seedlings show moderately-paced growth and multistemmed habit.
