A Word About WildflowersIn Big Bend National Park, our "spring" can begin as early as February. Mild temperatures continue through March and sometimes April. If we've had rain in the winter, we may have a spectacular wildflower bloom in early spring. Even without rain, you'll see the reliable spring bloomers such as yuccas, ocotillo, bicolor mustard, and bluebonnets.
Summer, with its relentless high temperatures, begins in May and can extend through September. The advent of the summer monsoons in July brings a little relief for both humans and plants. Afternoon rainstorms kick off a growth spurt that leaves the desert green and the flowers in bloom.
Color GuidesWith over 1200 species of plants, we can't show you everything, but here are some quick guides to get you started identifying the flowers that you see in the park.
