Broadleaf Sage Seeds
Herbs
About This Botanical
Broadleaf Sage is the kitchen garden's most fragrant culinary herb—its large, velvety grey-green leaves carry an intensely earthy, slightly peppery fragrance that is the soul of Thanksgiving stuffing, brown butter pasta, and roasted meats. A hardy perennial that grows more productive and beautiful each year, it asks only for full sun and excellent drainage in return for decades of generous harvests. Run your fingers through the leaves for an instant sensory experience that no dried herb can match.
Growing Instructions: Start indoors 6–8 weeks before last frost—sage germinates slowly and benefits from a heat mat for best results. Transplant after last frost to a sunny, well-drained location. In its first year harvest lightly to allow establishment; in subsequent years harvest freely. Trim after flowering to keep plants compact and productive.
