Bluebonnets are vibrant blue flowers that are native to the southern United States, particularly in Texas. They bloom in the spring and are known for their striking appearance, often covering fields and roadsides with a sea of blue. These flowers are part of the legume family and are the state flower of Texas. Bluebonnets thrive in well-drained soil and are often found in areas with full sunlight. They play a crucial role in local ecosystems by attracting pollinators like bees and butterflies.
