A hardy winter annual native to Texas. Adopted as the "State Flower of Texas", this is the most commonly seen variety along roadsides and in uncultivated pastures throughout the state. Flowers are densely arranged on a spike with a characteristic ice white terminal tip. Bluebonnets cannot tolerate poorly drained, clay based soils. Seed planted in poorly drained soils will germinate, but plants will never fully develop. Seedlings will become either stunted or turn yellow and soon die. Prefers a sloped area in light to gravelly, well-drained soil. Requires full sun.
