Sisyrinchium Californicum – Satin Flower 1 Litre

Sisyrinchium californicum, commonly known as Yellow-Eyed Grass, is a charming moisture-loving perennial admired for its bright golden-yellow star-shaped flowers and neat grass-like foliage. Perfect for pond margins, bog gardens, and damp borders, this attractive plant brings cheerful colour and a soft natural appearance to aquatic planting schemes.

Flowering from late spring into summer, Sisyrinchium californicum produces masses of vibrant yellow blooms held above slender green foliage, creating a striking contrast around the pond edge. Its compact growth habit makes it especially suitable for smaller ponds, container water gardens, and detailed marginal planting displays where subtle colour and texture are desired.

This hardy perennial works beautifully within wildlife-friendly gardens, attracting bees and pollinating insects throughout the flowering season. The tidy clump-forming foliage also helps soften pond edges while blending naturally with other moisture-loving plants.

Easy to grow and low maintenance, Sisyrinchium californicum thrives in consistently moist soil and shallow marginal conditions. Once established, it returns reliably each year and performs best in sunny positions where flowering is at its strongest.
