This is a desert species from the south western USA that grows 2.5 feet tall. Give it sharp drainage in full sun, and dry soils. Sow in early spring when the ground is still cool. Plants have lovely lavender - blue colored flowers that are not overly large and showy but make a nice mass blooming effect with thousands of flowers produced in crowded heads over many months. The flowers are cup shaped with white center markings and stamens that are long. The foliage is lacy and a medium green color and the stems are often tinted reddish. Use in any meadow type setting. Grown as Annuals that willingly self seed. Blooms well inside and only in five weeks from germination. The flowers are scented, somewhat like grape juice. The flowers are somewhat like Jacob's ladders and plants are durable and long blooming - they will self sow on open ground.
