Garnet Giant is the darkest broad leaf mustard variety with striking purple foliage and gently scalloped margins that develop rich color early, especially during spring and fall seasons. This heirloom cultivar delivers a mild, approachable flavor profile while maintaining the visual appeal that makes it ideal for both culinary and ornamental garden applications. Plant densely to encourage tender baby leaf production ready for harvest in approximately 21 days, or allow 45 days for full-sized mature leaves. The elongated petioles facilitate easy harvesting and handling. While this variety exhibits a tendency to bolt relatively quickly, strategic spacing and consistent moisture management help extend the productive window. Expect approximately 80% or better germination rates from our carefully selected seed stock. Each packet contains 200 non-GMO, heirloom seeds sourced for reliability and genetic integrity. Our commitment to sustainability extends throughout the entire product—from the seeds themselves to our reusable, recyclable, and climate-conscious packaging. An excellent choice for gardeners seeking both performance and environmental responsibility.
