I enjoy a vigorous vase-shaped two-foot tall plant that grows year end and year out in my rocky driveway without supplemental water. For best results, plant Blue flax in full sun and well-drained soil in a warm microclimate. Blue flax seeds survive in areas where soil has been disturbed soil, so it is useful in erosion control.<\/p>\n\n\n\n<p>Because Blue flax stays green throughout the growing season, it provides forage to native herbivores, and it resists fire. Birds use the seed in fall and winter.<\/p>\n\n\n\n<figure class=\"wp-block-image alignleft size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"493\" src=\"https:\/\/extension.colostate.edu\/gilpin\/wp-content\/uploads\/sites\/34\/2026\/01\/Linum-lewisii-4.jpg\" alt=\"A Photo of a Native Blue Flax\" class=\"wp-image-299\" style=\"width:325px;height:auto\" srcset=\"https:\/\/extension.colostate.edu\/gilpin\/wp-content\/uploads\/sites\/34\/2026\/01\/Linum-lewisii-4.jpg 750w, https:\/\/extension.colostate.edu\/gilpin\/wp-content\/uploads\/sites\/34\/2026\/01\/Linum-lewisii-4.jpg?resize=300,197 300w, https:\/\/extension.colostate.edu\/gilpin\/wp-content\/uploads\/sites\/34\/2026\/01\/Linum-lewisii-4.jpg?resize=600,394 600w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><\/figure>\n\n\n\n<p>Linum lewisii is available at nurseries.
