Growing notes
- Native to the Valdivian temperate rainforest of southern Chile — cool maritime climate
- Source of ulmo honey, a regional Chilean speciality with a strong almond flavour
- Demanding cultivation — needs cool moist conditions, succeeds in coastal western UK, Ireland, and New Zealand
- Long lived and slow growing — eventually a substantial forest tree
