Linum perenne Nanum ‘Blue Sapphire’ is a beautiful, compact perennial producing masses of delicate, sapphire-blue flowers above fine, narrow blue-green foliage. Its slender, branching stems create a wonderfully airy appearance, with an abundance of dainty, saucer-shaped blooms throughout summer.
Perfect for sunny borders, gravel gardens, and containers. Thriving in well-drained soil, it is wonderfully drought tolerant once established and provides a beautiful display of blue flowers year after year.
