Evening Primrose

Evening Primrose is a graceful biennial that opens its bright yellow flowers on warm summer evenings. The blooms release a sweet scent that attracts moths. From June to September, fresh flowers appear continuously along the upright stems. The plant self-seeds and naturalises beautifully in informal gardens.
