The touch, taste and smell of fresh herbs is always a delight, but especially so during a New England winter. A cool room with filtered southern light is all a gardener needs to successfully grow hers and be able to enjoy their fragrance and flavors. It is easy to root basil and other culinary herbs in water to enhance your favorite dishes. Many tender perennials such as scented geraniums can also spend the winter indoors. And it’s a perfect time to root stem cuttings in potting mix or water.
