Seeds of Ipomoea pandurata, Man of the Earth, or Bigroot morning glory. This plant rarely produces seeds and this is a wonderful opportunity to grow these vines. This native drought resistant perennial plant consists of a twining vine up to 20 to 30 feet long. It will climb adjacent vegetation readily, or sprawl across the ground in open areas. The stems are usually hairless and often reddish purple. Beautiful 3 inch white blossoms have wonderful bright magenta centers. The root system produces large tubers that can lie several feet beneath the ground surface and weigh up to 20 to 30 lb.
