Growing notes
- Plant where the fragrance can be enjoyed close at hand — fragrance fills the surrounding air in early summer (May–June)
- Cut back hard after flowering — flowers on previous year’s wood, so pruning timing matters
- Not related to orange (Citrus) — the name reflects the fragrance only
- Compact cultivars (‘Belle Etoile’, ‘Manteau d’Hermine’) suit smaller gardens
