Summer/fall bloomVery frost hardy
In spring, 6 weeks before last expected frost date, sow seeds 2 inches apart in a container of seed starting mix and cover 1/4 inch deep. Keep cool, between 60-70°F (16-27°C) and moist and provide a strong light source until ready to plant out. Rose seeds germinate slowly, so be patient. Once seedlings are large enough to handle, transplant into individual pots. Feed seedlings every 2 weeks with half-strength fertilizer. When 3 to 4 inches tall, gradually acclimate seedlings to outdoor conditions and plant out in full sun.
Space seedlings 18 inches apart so plants can mature and spread.
