About the bluebonnet

Texas named the bluebonnet its state flower in 1901. The original law honored a single species (Lupinus subcarnosus), but in 1971 the legislature broadened it to include every bluebonnet species found in the state. Its dense spikes of blue, pea-like blooms tipped with white have become an emblem of Texas itself, and family photos among the bluebonnets are a springtime tradition.

Where it grows

Bluebonnets are native to Texas and thrive in full sun and well-drained soil, germinating in autumn and bursting into bloom from late March into April.
