Lupine, Texas Bluebonnet Flowers

The Texas Bluebonnet Lupine (Lupinus texensis) is so named because the blossoms resemble the bonnets worn by pioneer women. This low-growing annual is in the legume family, so it fixes nitrogen in the soil and is a great companion plant or cover crop for the vegetable garden. Produces upright spikes of pea-sized blossoms in rich blue with white tips, but can also pop up in shades of white, pink, purple, and maroon (“Aggiebonnet”). Grows 1'-1.5' tall on sturdy stems with daisy-like palmate foliage. Spectacular in a pot or blanketing an entire field. The state flower of Texas.

If consumed in large quantities, seeds can be toxic to people, pets, and livestock.
