Shaped like a small crescent moon, moonseeds possess green leaves that grow between 5 and 20 centimeters in diameter. The berries only reach 1.5 centimeters in diameter. Black in color, moonseeds have an appearance that mimics the fox grape.

Mistaking delicious fox grapes for moonseeds can lead to serious consequences. Found in humid wooded environments, moonseeds also grow in thickets that line banks of rivers and streams.

The rank taste of the berries is the only salvation for avoiding the highly toxic poison. You can avoid severe symptoms by only tasting the berry and moving onto another plant. More than just a taste results in violent convulsions and that leads to eventual death.
