Garden & Ecology Notes

Wildlife Value:
bees, butterflies, hummingbirds
Deer Resistant:
Yes
Fragrant:
Yes
Fire Ecology:
Fire adapted — tolerates or benefits from fire

Resprouts from woody root crown after fire. Common in fire-prone montane and chaparral communities.

Soil Requirements

Soil Type:
rocky, well-drained, nutrient-poor soil
pH:
6.0 - 7.5 (slightly acidic to neutral)
Drainage:
excellent drainage required
Moisture:
dry to moderate
Notes:
thrives in mountainous regions

Propagation & Germination

Stratification:
Cold/moist stratification required — 30–90 days
Germination Time:
14–42 days
Notes:
Surface sow; seeds require light for germination. Cold stratification improves germination rates.

The above propagation data sourced from Claude AI

Pre-treatment: Sow seed into trays filled with stabilized medium plugs (Q-plugs). Seal trays inside plastic bags and refrigerate at 1 to 3 °C for 14 days. Check trays weekly and keep moist. If mold is evident, treat trays with 1% hydrogen peroxide. Alternatively, cold-moist stratification for 90 days can be used for higher germination rate.

Establishment: M. odoratissima grows in montane forests and amongst sagebrush scrub above 600 to 3000 m in Canada, Washington, Oregon, Idaho, California, and Nevada. It is found in Northern California coast ranges, Cascade Range, the Sierra Nevadas, Modoc Plateau, White Mountains, and Inyo Mountains. M. odoratissima will grow in wet or dry, rocky, and sandy soils. There is a variation in germination rate based on the stratification period.

ORGHPS Germination Guide: Sow at 4°C for 3 months, then place @ 20°C for 3 months. Requires light or the seed is very fine. Surface sow and expose to light. * 5% germination rate
