Hope no one minds.

The aroma of leaves, stems, and other plant parts can be even more powerful than flower fragrance in the garden. The plants we call "herbs", like rosemary, thyme, lavender, basil, oregano, and mint, are most obvious for their foliage fragrance. Other herbaceous perennials with aromatic foliage include yarrow (Achillea), hyssop (Agastache), mugwort/wormwood (Artemesia), bluebeard (Caryopteris), sweet woodruff (Galium), bigroot cranesbill (Geranium macrorrhizum cultivars), beebalm/bergamot (Monarda), sage and Russian sage (Salvia and Perovskia), and lavender cotton (Santolina). All these plants are suitable for New England gardens, many are drought-tolerant, and some even have distinctive silvery-colored leaves that add to their visual appeal.
