Oenothera macrocarpa

Huge golden flowers steal the spotlight with Oenothera macrocarpa. Also known as Missouri evening primrose, this low-growing perennial spreads gently across the ground with silvery-veined foliage and trailing stems, creating a striking carpet of colour from early summer to autumn onwards. The silky blooms can reach an impressive size, opening wide in sunshine and glowing against gravel, stone and dry borders. Its relaxed, sprawling habit gives planting schemes a natural, sun-baked character, while the vivid yellow flowers bring energy and brightness for weeks on end. Exceptionally eye-catching and full of prairie charm, it is a superb choice for rockeries, slopes and Mediterranean-style gardens. Ultimate height: 20cm (8in). Ultimate spread: 50cm (20in).Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size.
