A Slew of Blue

A bluebonnet is a bluebonnet … until you really get to know them

The original state flower of Texas was a bluebonnet, but critics said the species, Lupinus subcarnosus, wasn’t worthy of the title. So lawmakers declared all varieties of bluebonnet as the official state flower, including the more popular Lupinus texensis.

You don’t have to speak Latin or be a horticulturist to fully appreciate Texas bluebonnets, which aren’t even always blue anymore.
