Collards, often referred to as collard greens, are a member of the Brassica family, closely related to kale and cabbage. They are frost-tolerant, which can enhance their flavor and sweetness when grown in cooler months.

Characteristics:

1. Maturity Period: Collards typically mature in 70 to 90 days, depending on the growing conditions. Young leaves can be harvested earlier for a more tender product.
2. Yield: Known for their high yield, collards produce an abundance of leaves that can be harvested multiple times throughout the growing season.
3. Resistance: Collards are generally resistant to common pests and diseases that affect brassicas. However, good cultural practices, such as crop rotation, can further minimize issues.
4. Nutritional Value: Collards are rich in vitamins A, C, and K, along with dietary fiber, calcium, and iron. They are a highly nutritious green leafy vegetable, providing numerous health benefits.
