Linum Perenne 'Nanum Sapphire'

Blue Flax

Linum nanum ‘Sapphire’ (Dwarf Flax) is a compact, fine-textured perennial with a low, mounded habit, featuring slender, needle-like green foliage and abundant clear sky-blue flowers that bloom over an extended period from late spring into summer. The delicate, airy appearance and continuous bloom make it a standout in sunny, dry gardens.
