Propagation & Germination
- Stratification:
- Cold/moist stratification required — 60–90 days
- Germination Time:
- 14–30 days
- Notes:
- Seeds require cold stratification for 60-90 days; surface sow on moist medium and keep at 20-25°C after stratification.
Pre-treatment: Mix the seeds with an equal amount of either perlite or vermiculite in a sealable plastic bag or container. Store in a cold environment (35-42°F) for 1-2 months. Seed germinates in light, so it should be surface-sown.
Establishment: Seeds are collected by hand from locally native plants within the eastern central Upper Peninsula or in Great Smoky Mountains National Park. Seed is small and difficult to sow evenly. If pappus is left on the seed, sow in clumps. If pappus has been removed, cleaned seed can be mixed with talc and sown using a salt shaker.
