Creating a vermouth garden in outdoor plant boxes is a delightful way to grow aromatic herbs and flowers that enhance homemade vermouth. The best plants for this purpose include classic botanicals like wormwood (Artemisia absinthium), which provides the signature bitter note, and sweet basil (Ocimum basilicum) for its fragrant leaves. Thyme (Thymus vulgaris) and rosemary (Rosmarinus officinalis) add earthy depth, while chamomile (Matricaria chamomilla) offers a floral touch. For a citrusy twist, consider lemon verbena (Aloysia citrodora) or bergamot (Monarda didyma). These plants thrive in well-draining soil and sunny spots, making them perfect for container gardening. Regular pruning ensures healthy growth and maximizes flavor for your vermouth recipes.
