Useful for its tiny, bright blue blossoms and heat and drought tolerance, Blue Flax adds charm to a sunny and dry garden. Hardy enough for windy sites and high-elevation gardens. Perfectly sized for the middle of the border in any climate, especially with its red cousin, Scarlet Flax (Linum grandiflorum rubrum). Adds pretty contrast in a rock garden with California Poppy (Eschscholzia californica) and the slightly bigger Lance-leaved Coreopsis (Coreopsis lanceolata).
