Wormsbane

Wormsbane is a plant growing on the Mars of the late 19th century, found in Martian Dreams.

Description
When in the nightmare of George Washington Carver, the Avatar learned of a plant named Wormsbane, which Carver wanted the Avatar to use to scare away worms - they reacted badly to the blossom of the plant - while he'd grow in a martian pod in his dream. One just had to drop a seed onto open soil and then water it for the plant to grow. Watering it more made it blossom, so that eventually a seed could be aquired. Waiting for too long to get the seed would in the dream cause the plant to wither and die, losing the seed in the process.

Back in reality, the Avatar found a big field of these plants growing east of Argyre, on the other side of the canal, and could use these plants for real to keep off annoying worm-type enemies.
