Bean Seeds - Scarlet

Scarlet bean seeds grow into vigorous, climbing plants with a strong vining habit and consistent seasonal growth. This bean type is well suited to warm and mild climates and is commonly grown on trellises, poles, or fences to maximize vertical space. Scarlet beans perform well in garden beds, raised beds, and large containers when planted in well drained soil with regular moisture. Seeds are typically direct sown after frost risk has passed, supporting reliable growth throughout the season.
