Collard green seeds - Vegetable Plant

Collard greens are a cool-season leafy vegetable known for their upright growth and broad, smooth leaves. They form a loose rosette of foliage and continue producing leaves throughout the growing season. This plant grows well in temperate climates and performs best in full sun to partial shade with fertile, well-drained soil. Collard greens establish steadily and are suitable for garden beds, raised beds, and container planting, adapting well to continuous harvesting.
