Rose, Seed (P)
Rosa chinensis minima
Perennial. Hardy in zones 5-9.
May overwinter in zones 3 and 4 with protection. Start inside 8-12 weeks before planting out. Germinate at 15°C (59°F) for 30-60 days. Lightly cover seed and provide light. Germination may be erratic. This rose flowers when very young. Plant out after last frost or when plants are hardened off. Prefers full sun and well-drained soil, rich in organic matter, pH 6-6.9. Plant in full sun location 18" apart. You can also grow as a container plant, but the container must be protected over the winter. Deadhead regularly and prune in spring or fall. Fertilize once a month with a balanced fertilizer. Generally pest free, but may be susceptible to mildew and spider mites if stressed. Mulch after the ground freezes. Can only be grown inside if you can provide at least 4-6 hours of direct sunlight per day all year. This means providing florescent lights in winter. Normal room temperatures are fine. You can bring container plants inside to enjoy blooms and then put them back outside.
