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.
Growing Instructions for the Texas Bluebonnet
The seeds have a hard seed coat that has to be treated, or scarified, in order for water to enter the seeds so that they can sprout. 1. Scarify the seeds by nicking or sanding the seed coat. The seeds can be sanded with sandpaper, a nail file or an emery board. 2. Soak the seed in water for several hours. 3. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Water the mixture so that it is moist but not wet. 4. Put the seeds on the soil. 5. Cover the seeds with a thin layer of soil. 6. Water the seeds. 7. Place the pots in an area with warm temperatures in full sun or part shade. 8. When the seedlings are a few inches tall, they can be transplanted.
