Bright Blue is a named blue-flax selection with vivid flowers carried above fine, wiry stems. Perennial flax has narrow leaves and successive blooms that open in sunny mornings, bringing a light, airy look to a sunny border.\n\n## Garden Use\nPlace Bright Blue where its blue flowers can brighten a gravel garden, a mixed perennial border, or an informal planting. The species commonly grows as a short-lived, clump-forming perennial; exact dimensions vary among garden selections and conditions, so preserve the plant’s existing size range when planning.\n\n## Growing Conditions\nFull sun encourages the strongest growth and flowering, though light shade is tolerated. Choose freely draining soil; perennial flax can grow in dry or rocky ground, while heavy clay may leave roots shallow. The [NC State perennial-flax guide](https://plants.ces.ncsu.edu/plants/linum-perenne/common-name/perennial-flax/) describes its flower cycle, site needs, and care.\n\n## Maintenance\nAfter flowering, cut stems back by about half to keep the plant from becoming leggy; trimming midway through the bloom period may extend flowering. Leave seed capsules if you want seedlings in open ground, or remove them before they mature to reduce self-seeding. Avoid disturbing the crown during winter and early spring.
