Both parts are typically prepared in simple dishes without complex recipes. This plant is a hardy perennial, growing rapidly and thriving in zones 5-12. It can be propagated by seed or division, though seeds are more commonly used. While biscuitroot is not known for medicinal properties, it holds culinary significance as an edible wild food.
