Mint - Culinary Herb. The name alone conjures up a refreshing image of the unlimited uses of mint; soothing mint tea, fine deserts and drinks garnished with fresh sprigs of mint and holiday mint candy canes hanging on the Christmas tree. Mint is a perennial with bright green, saw-toothed leaves. It is easy to grow, loves the sun and will thrive with regular harvesting of the leaves. Seeds will germinate 10-15 days after planting and you will be able to harvest the fragrant leaves after about eight weeks.
