Evening Primrose

About this plant

Oenothera berlandieri 'Siskiyou', commonly known as Evening Primrose, is a delightful perennial prized for its abundant, saucer-shaped, satiny pink flowers that unfurl from late spring through fall. Each blossom, approximately 2 inches wide, features a prominent yellow eye and a charming, ethereal quality, creating a soft, romantic feel in any garden. This cultivar is a vigorous, spreading perennial, forming a dense mat of lance-shaped, grey-green foliage. It's an excellent choice for groundcover, quickly filling in boş spaces and providing a living carpet of color. Its adaptability and extended bloom time make it a go-to for gardeners seeking continuous visual interest with minimal fuss. 'Siskiyou' is exceptionally resilient, thriving in hot, dry conditions and poor soils once established. Its ability to naturalize makes it ideal for rock gardens, cottage gardens, and large landscape plantings where a durable and beautiful perennial is desired. While it spreads, it's not overly aggressive, offering a welcome pop of color without becoming unruly.

Care & maintenance

Evening Primrose 'Siskiyou' is incredibly low-maintenance. Water regularly during its first growing season to establish a strong root system. Once established, it is highly drought-tolerant. Deadheading spent blooms can encourage more flowers, though it's not strictly necessary for performance. Cut back foliage in late fall or early spring to refresh growth.
