Creating a honey infusion garden in outdoor plant boxes is a delightful way to attract pollinators and enhance your garden's ecosystem. The best plants for this purpose are those that produce abundant nectar and pollen, ensuring a steady supply for bees and other beneficial insects.

1. Lavender: A favorite among bees, lavender's fragrant blooms are rich in nectar and thrive in sunny outdoor plant boxes.

2. Thyme: This hardy herb offers tiny flowers packed with nectar, perfect for honey infusion and culinary use.

3. Borage: Known as the "bee plant," borage’s star-shaped blue flowers are a magnet for pollinators.

4. Mint: Spearmint and peppermint produce small but nectar-rich flowers, ideal for honey gardens.

5. Rosemary: Its early spring blooms provide essential food for bees emerging from winter.

For optimal results, mix these plants in your outdoor plant boxes to create a diverse and vibrant honey infusion garden. Ensure they receive plenty of sunlight and well-draining soil. By planting these bee-friendly varieties, you’ll support local pollinators while enjoying the added bonus of fresh herbs and fragrant blooms. Happy gardening!
