Choose the perfect plants for your garden-themed fairy garden. Opt for small, low-maintenance plants like succulents, moss, and miniature ferns. These plants not only add greenery to your garden but also create a sense of scale and proportion. You can also include colorful flowers like miniature roses, pansies, and daisies to add pops of color. Remember to choose plants that thrive in your local climate and provide them with proper care to ensure their health and longevity.
