You’ll find them throughout the year in Houston—lyre-leaf sage, Drummond skullcap, silver-leaf nightshade, snow-on-the-prairie, lemon beebalm, scarlet pimpernel, plains wild indigo, spring ladies’-tresses, deer pea vetch. These wildflowers and hundreds of other species flourish in this part of Texas, but until this book was published in 1993 no guide had focused exclusively on the Houston area. John and Gloria Tveten spent years seeking out both the common and the rare flowers. They describe here more than 200 plants. A color photograph of each one will make identification easy. The guide is arranged by color, with each entry tracing the history and lore of a species. Many plants—for example, prairie Indian plantain and self-heal—were used by Native Americans for medicinal purposes. Others, like pokeweed and wapato, are edible. Southern dewberry and giant ragweed are used as natural dyes. And some, like rattlebush and milkweed, are poisonous. At the end of each species account is a list of key identifying characteristics for quick reference in the field. Summaries of plant families are also included, as well as tips on where and when to look for wildflowers.
