Gardeners often view weeds as enemies to be eradicated. However, many plants typically labeled as “weeds” actually offer significant benefits to your garden and surroundings. These so-called nuisances can support pollinators, enrich the soil, and even provide edible or medicinal uses. By rethinking your approach to some of these plants, you might discover natural allies for creating a thriving, self-sustainable ecosystem in your garden.
Here are 20 beneficial weeds you may want to leave alone—or even intentionally cultivate—in your garden.
1. Common Violet (Viola sororia)
