About this plant
Sisyrinchium angustifolium 'Devon Skies' produces clear sky-blue flowers with golden yellow centers held above slender, grass-like foliage. Blooms appear in late spring and often continue into early summer, opening in sunlight and closing on cloudy days. Narrow, upright leaves form tidy clumps that maintain a clean, linear presence through the growing season. The flowers are star-shaped with well-defined petals, creating a crisp, luminous effect that reads clearly even at a distance.
Native to eastern North America, this selection is valued for edging paths, filling sunny borders, and weaving through gravel gardens or meadow-style plantings, where its fine texture integrates easily with other perennials.

Design tip
Scatter repeating clumps through sunny borders to create a natural rhythm that feels light and effortless. Blend the fine foliage with broader leaves and airy flowering perennials, allowing the blue blooms to punctuate the planting with seasonal color and movement.
