Season & Zone
Exposure: Full sun to partial shade
Direct sow in early spring when a light frost is still a possibility, or direct sow in the fall in mild winter areas. Erysimum is very susceptible to damping off, but if you want to try sowing indoors, do so 4-8 weeks before planting out after the last frost. Maintain a soil temperature of 18-25°C (65-75°F) and water only from below. Provide ventilation.
Sow seeds 5mm (¼”) deep. Space plants around 25-30cm (10-12″) apart.
Grow in neutral to slightly alkaline, average garden soil. Pinch growing tips in spring to encourage bushiness. Plants can be discarded after blooming or kept in situ and mulched in the autumn.
