Creating a lush and sustainable vetiver garden in outdoor plant boxes requires careful selection of companion plants that thrive alongside vetiver grass. Vetiver (Chrysopogon zizanioides) is a hardy, deep-rooted plant known for its soil-stabilizing properties and aromatic roots. To enhance its growth and aesthetic appeal, consider pairing it with these ideal plants:

1. Lemongrass (Cymbopogon citratus) – Shares similar sunlight and water needs, creating a harmonious tropical vibe.

2. Marigolds (Tagetes spp.) – Their pest-repellent qualities protect vetiver while adding vibrant color.

3. Basil (Ocimum basilicum) – A fragrant herb that complements vetiver’s aroma and attracts pollinators.

4. Sweet Alyssum (Lobularia maritima) – Low-growing and drought-tolerant, it acts as a living mulch.

5. Lavender (Lavandula spp.) – Adds visual contrast and thrives in well-drained soil like vetiver.

For optimal results, ensure your outdoor plant boxes have good drainage and receive full sun. Regularly trim vetiver to encourage dense growth and prevent overcrowding. With the right companions, your vetiver garden will be both functional and visually stunning.
