Jicama is a tropical legume grown for its crisp, sweet, starchy root. It requires a very long, warm growing season but produces a refreshing, water chestnut-like tuber.

Crane County, Texas is in USDA Zone 7b. The average last spring frost is March 20 and the first fall frost is November 12, giving you a growing season of approximately 237 days.

At an elevation of 4,486 feet, Crane County receives approximately 46.8 inches of rainfall annually with predominantly sandy loam soil.
