Evening primroses, Oenothera, are a group of annuals, biennials and perennials, native to North and South America. They’re so-called because the flowers of many species open in the evenings to attract pollinators that are specialised to collecting pollen from them. Many evening primroses have richly scented flowers.
Oenothera ‘Crown Imperial’ bears a close resemblance to crown imperials (Fritillaria imperialis), hence the cultivar name. Each flower bud is a warm orange before opening to reveal a bright yellow bloom. The flowers have a light fragrance.
For best results, grow Oenothera ‘Crown Imperial’ in full sun in well-drained soil. ‘Crown Imperial’ is a sterile cultivar, so won’t self-seed like many other evening primroses. Propagate Oenothera ‘Crown Imperial’ by taking root cuttings in early spring.
