A world-famous favorite, this native Texan lupine creates one of the globe's top natural wildflower displays. Along with other bluebonnet species, it is the Texas state flower, this particular variety being by far the most-loved. Occasionally, all shades of pink are seen, but the most well-known and common color is the deep and rich royal blue. Bluebonnets usually bloom from early March to mid-April or later depending on spring temperatures. The flowers are held on a 7-12 inch stalk, with deep bright blue flowers at the bottom to white on the top. After the flowers fade, seeds form. Because it is an annual, the flat 1/8 inch seeds must fully mature in the pod and fall to the ground to assure a display next year without re-planting. Texas Bluebonnets should be planted in full sun, at least 8-10 hours a day. They prefer well-drained soils and are drought tolerant.
