Parts I and II can be viewed in one long or two shorter programs. Historic Uses of North Texas Plants: covers the interesting and sometimes surprising uses of our native plants over the years—from prehistoric times to modern day. Beyond the obvious uses of food, clothing and shelter, native plants have been used as dyes, medicines, industrial materials, toys, for rituals, theatre effects, pollution detectors and more. Emphasis is on plants found in North Central Texas, but many of the plants are found in other regions too.
