Oenothera speciosa Alba

Common Name:
White Evening Primrose

Description:
Oenothera speciosa ‘Alba’ is a graceful, low-growing perennial known for its delicate, pure white, cup-shaped flowers that open wide to reveal soft yellow centres. This charming plant creates a light, airy display from spring through to summer, often continuing into early autumn under favourable conditions. Its spreading habit forms a natural ground cover, with slender green foliage providing a soft backdrop to the luminous blooms, which can take on a subtle blush as they age. Well-suited to Melbourne’s climate, it thrives in full sun and well-drained soils, tolerating dry conditions once established. Oenothera speciosa ‘Alba’ is ideal for cottage gardens, borders, and naturalistic plantings, where it can gently weave through surrounding plants. It is valued for its resilience, low maintenance requirements, and ability to attract pollinators, though it can spread freely if left unmanaged.
