Creating an infused oil garden in outdoor plant boxes is a rewarding way to grow herbs and flowers for natural, aromatic oils. The best plants for this purpose are those with strong essential oils and easy-to-harvest leaves or flowers.

1. Lavender: Known for its calming scent, lavender is perfect for infused oils used in skincare and relaxation. Its purple blooms are easy to dry and steep in carrier oils.

2. Rosemary: This hardy herb offers a robust aroma and is ideal for culinary and therapeutic oils. It thrives in sunny outdoor plant boxes.

3. Calendula: With bright orange or yellow flowers, calendula is excellent for soothing skin oils. It’s also a great companion plant.

4. Mint: Peppermint or spearmint adds a refreshing twist to infused oils, perfect for DIY lip balms or muscle rubs.

5. Chamomile: Its delicate flowers create gentle, calming oils for skincare or tea blends.

For success, ensure your outdoor plant boxes have well-draining soil and receive ample sunlight. Harvest leaves or flowers in the morning for peak oil content. Experiment with single plants or combinations to create unique infused oils for home use. Happy gardening!
