Description

Sisyrinchum angustifolium – Blue Satin Flower 1 Litre

Sisyrinchium angustifolium, commonly known as Blue-Eyed Grass, is a charming moisture-loving perennial that produces delicate violet-blue star-shaped flowers above neat clumps of slender grass-like foliage. Despite its common name, this attractive plant is actually part of the iris family and is perfect for adding soft colour and texture to pond margins, bog gardens, and damp planting areas.

Flowering from late spring into summer, Sisyrinchium angustifolium creates a natural cottage garden feel around ponds and water features while remaining compact and easy to manage. The bright flowers open in sunny conditions and contrast beautifully against the fresh green foliage, making it an excellent choice for softening pond edges and adding seasonal interest.

Its compact habit makes it particularly suitable for smaller ponds, container water gardens, and mixed marginal planting displays. The flowers are also attractive to bees and pollinating insects, helping to support biodiversity within the garden.

This hardy perennial thrives in consistently moist soil and can tolerate shallow marginal conditions, performing best in sunny positions where flowering is at its strongest. Once established, it requires very little maintenance and returns reliably each year.
