Perennial | Shade-Tolerant | Pollinator-Friendly
Seed Treatment:
- Soak seeds in room-temperature water for 12–24 hours.
- Cold stratify for 2 weeks in the fridge. Place seeds on a moist paper towel in a zip-lock bag. If seedlings emerge during stratification, remove and plant immediately.
Best Time to Sow:
Indoors: 6–8 weeks before last frost
Outdoors: Late spring or early autumn when soil is cool but not frozen
Optimum Temperature for Germination:
68–72 °F (20–22 °C) – avoid fluctuations, especially cold night temps
Germination Time:
14–30 days (after stratification)
How to Sow:
• Requires light to germinate – surface sow and press lightly into moist soil
• Do not cover with soil or vermiculite
• Use a fine mist to water gently
• Cover with humidity dome or plastic wrap until germination
Watering:
• Keep soil consistently moist, never soggy
• Mist daily or bottom-water to avoid displacing seeds
Light Requirements:
• Bright, indirect light indoors
• Partial shade to full shade outdoors
Post-Germination Care:
• Remove cover as soon as seedlings appear
• Thin to strongest seedlings once they have true leaves
• Harden off indoor-grown plants gradually before transplanting
Growing Tips:
• Prefers moist, well-drained soil rich in organic matter
• Tolerates heat and humidity once established
• Mulch to conserve moisture and reduce weeds
• Flowers attract hummingbirds and beneficial insects
• Remove faded blooms to prolong flowering
• Excellent for borders, woodland gardens, and containers
