Creating a thriving rosemary garden in outdoor plant boxes requires thoughtful companion planting. Rosemary, a hardy and aromatic herb, pairs well with plants that share its love for well-drained soil and sunny conditions. Here are the best plants to grow alongside rosemary for a vibrant and productive garden:

1. Lavender – Both Mediterranean natives, lavender and rosemary thrive in similar conditions, offering a beautiful contrast in color and fragrance.

2. Thyme – This low-growing herb complements rosemary’s upright growth and enjoys the same dry, sunny environment.

3. Sage – Another drought-tolerant herb, sage enhances rosemary’s flavor and deters pests naturally.

4. Marjoram – With its gentle aroma, marjoram attracts pollinators while benefiting from rosemary’s pest-repellent properties.

5. Oregano – A robust herb that spreads easily, oregano pairs well with rosemary and thrives in similar conditions.

Avoid planting moisture-loving herbs like mint or basil near rosemary, as their watering needs differ. By selecting the right companions, your rosemary garden will flourish in outdoor plant boxes, offering both beauty and culinary benefits. Happy gardening!
