Wormwood
Wormwood is a silver-leaved perennial with a strong, bitter aroma that insects avoid. This hardy plant produces compounds that repel mosquitoes, flies, and even moths. It prefers dry soil and full sun, making it a great choice for low-water gardens. Wormwood works best when planted along borders or used as an ornamental filler between other herbs. While it doesn’t attract pollinators like some other plants, its foliage adds texture and contrast to any garden bed. Keep in mind that wormwood is toxic if consumed, so avoid planting it in areas accessed by pets or children. For a rugged, elegant way to repel pests, wormwood holds its own.
