Horticultural & Botanical History

‘As I suspected, when I first described this plant, ten years ago, in the Exotic Flora, this fine and fragrant species of Evening Primrose has proved perfectly hardy, producing its lovely cream-coloured blossoms, which change to rose-colour in decay, in the open border, during the months of July and August. […] Like some other species of this Genus, the scent of the blossoms is most powerful in the evening.  The flowers continue many days in perfection, and are most fully expanded at the approach of night.’  [BM t.3189/1832].  Introduced to Britain in 1821.  [JD].  Paxton’s Dictionary lists the variety major.
