Garden & Ecology Notes
- Wildlife Value:
- birds
- Fire Notes:
- As an obligate parasite on western larch, survival depends on host tree survival. Western larch is fire-adapted with thick bark, but severe fires can kill infected branches.
Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Germination Time:
- 14–30 days
- Notes:
- Seeds are explosively discharged from fruit and stick to host bark. Germination occurs on host tree bark only, requiring contact with larch branches.
