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.
