Ever wonder how the bluebonnet got its name? It's straight from history - pioneer women wore sunbonnets as sun protection that resembled the shape of this flower's petals. Bluebonnets hold a solid place in Texas history, having been mentioned in pre-Columbian Native American writings.
As the state flower, Texas bluebonnets have a special place in the heart of Lone Star State gardeners. You can plant a sea of these vivid blue blossoms, plant them in patches, or use them as border plants. According to the Lady Bird Johnson Wildflower Center, the best time to plant bluebonnet seeds is October and November; early October is optimal.
Bluebonnets are annuals that grow during the winter and blossom from the end of March to mid-May. They thrive in areas with full sun and good drainage, in soil that is slightly alkaline. During seasons with normal rainfalls, bluebonnets only need occasional watering, but make sure not to over-saturate them. Fertilization is only necessary in early spring if seedlings don't seem to be growing well, otherwise they're well adapted to low-nutrient soil and fertilizing isn't recommended.
