How to Grow Texas Bluebonnet Flower Plants

Like other wildflowers, Texas Bluebonnets are a low-maintenance plant. They grow best in full to partial sun. They will do well in gravelly, well-drained soils. However, do not like heavy, clay soils that retain a lot of moisture. The plants are drought-tolerant and prefer dry soil conditions. You should not have to water this hardy plant.

Adding a general-purpose fertilizer once or twice during the season will help to promote maximum growth and bloom. We recommend one fertilizer feeding a couple of weeks before blooming.

Texas Bluebonnet plants will require little maintenance. Once established, they will thrive all season long. That leaves you with time to tend to other plants, and to enjoy the sea of blue spring blooms atop your Texas Bluebonnet.
