How to Seed Cupflower ‘Purple Robe’ (Nierembergia hippomanica)

1. Sowing Time:
   Sow indoors from February to April, about 6–8 weeks before the last frost. Transplant outdoors in May, once the weather is warm and frost-free. In mild climates, seeds can also be sown outdoors in April–May.

2. Sowing Depth:
   Sow seeds on the surface of moist seed compost and press gently. Do not cover, as light is required for germination.

3. Soil:
   Prefers well-drained, fertile soil enriched with compost or organic matter. Ideal for loamy or sandy soil with good drainage.

4. Light & Temperature:
   Place in a bright, warm location with temperatures around 20–24 °C (68–75 °F). Avoid direct, strong sunlight during germination.

5. Germination Time:
   Seeds usually germinate within 14–21 days in warm, moist, and well-lit conditions.

6. Transplanting:
   When seedlings are strong enough to handle, transplant them outdoors, spacing 20–25 cm apart in sunny borders, hanging baskets, or containers.

7. Growing Tips:

   • Keep soil consistently moist but well-drained.

   • Choose a sunny or lightly shaded spot for best flowering.

   • Apply a balanced liquid fertilizer every 2–3 weeks during the growing season.

   • The ‘Purple Robe’ variety produces lavender-purple cup-shaped flowers with a golden center, ideal for containers, edging, and hanging baskets.

   • Blooms continuously from late spring to autumn, attracting bees and pollinators.
