Creating a bitters garden in outdoor plant boxes is a fantastic way to grow flavorful and medicinal herbs in limited spaces. The best plants for bitters gardens thrive in containers and offer a balance of bitterness, aroma, and health benefits.

1. Dandelion (Taraxacum officinale): A classic bitter herb, dandelion is hardy and easy to grow in plant boxes. Its leaves and roots are rich in nutrients and perfect for digestive teas.

2. Chicory (Cichorium intybus): Known for its slightly bitter leaves and roots, chicory adds depth to salads and brews. It prefers full sun but tolerates partial shade.

3. Wormwood (Artemisia absinthium): This potent bitter herb thrives in well-drained soil and is ideal for small spaces. Use sparingly in bitters or herbal remedies.

4. Mugwort (Artemisia vulgaris): A resilient plant that grows well in containers, mugwort is valued for its digestive and calming properties.

5. Angelica (Angelica archangelica): A taller option for plant boxes, angelica offers bitter-sweet flavors and thrives in partial shade.

For optimal growth, ensure your plant boxes have good drainage and receive at least 4-6 hours of sunlight daily. Mixing these bitter herbs with milder greens like mint or lemon balm can create a balanced container garden. Regular pruning will keep plants compact and productive.

Whether for culinary use or herbal remedies, these plants will transform your outdoor plant boxes into a thriving bitters garden.
