Sundrops (Oenothera fruticosa)Sundrops is a tough, sun-friendly perennial that brings bright yellow flowers when the garden is shifting from late spring into summer. It forms a tid y clump of narrow green foliage that looks clean even between bloom waves, then keeps pushing fresh flowers over an extended season. Also known as narrowleaf sundrops, it is a practical pick for borders that need reliable color without heavy watering. Once established, it handles heat and dry spells with confidence as long as the soil drains well.Distinctive FeaturesThis evening primrose relative produces cup-shaped, clear yellow blooms that open in succession, creating a long-running display rather than a single short flush. The habit is upright and clump-forming at first, with the ability to slowly spread into a wider patch in favorable conditions. Foliage is narrow and fresh green, creating a fine texture that pairs easily with grasses and broader-leaved perennials. It is especially valuable for adding sunny color and an easy, natural look in places where fussier plants struggle.Growing Conditions Sun: Full sun for best flowering, with light partial shade tolerated. Soil: Well-drained soil is essential, and it adapts to sandy, rocky, and average garden soils. Water: Dry to medium moisture, water to establish, then water only during extended drought.

Pruning: Cut back stems after the main bloom period if foliage looks tired, which can refresh growth. Watering: Water deeply during prolonged drought, especially in the first year. Division: Divide clumps every few years to maintain vigor and manage spread. Soil Management: Avoid overly rich soil and heavy fertilizer, which can encourage looser growth. Why Choose Sundrops?
