Seed Treatment
- Cold Stratification Method:
- Place seeds on a moist paper towel, seal in a plastic bag.
- Refrigerate at 35–40°F (1–4°C) for 3–4 weeks.
- Check occasionally to keep the medium moist, not wet or moldy.
Planting Instructions
- Sowing Time:
- Indoors: Start seeds indoors 6–8 weeks before the last frost.
- Outdoors: Sow in early spring or late fall for natural cold stratification.
- Soil Requirements:
- Prefers moist, well-draining, humus-rich soil.
- Slightly acidic to neutral pH (6.0–7.0).
- Light Requirements:
- Thrives in partial shade to full shade. Ideal for woodland or shaded rock gardens.
- Sowing Instructions:
- Surface sow seeds; do not cover, as they need light to germinate.
- Optimal temperature: 60–65°F (15–18°C). Avoid high temperatures, as they may inhibit sprouting. Also, ensure the soil remains moist but not waterlogged.
- Mist gently to settle seeds into place.
- Watering:
- Keep soil evenly moist during germination—avoid waterlogging.
- Once established, water regularly during dry spells.
- Germination Time:
- Expect germination in 14–30 days under ideal conditions.
- Spacing:
- Thin or transplant seedlings 6–12 inches (15–30 cm) apart for spreading clumps.
Growing Tips:
- Saxifraga umbrosa forms attractive evergreen rosettes and delicate pink or white blooms.
- Great for ground cover, shady borders, and rockeries.
- Mulch lightly to retain moisture and suppress weeds.
- Low-maintenance and tolerant of cool, damp conditions.
