There's no better neighbor for it than marjoram. Companion plants - like rosemary and thyme, or tomatoes and marigolds - are plants that thrive under the same growing conditions.

Marjoram and lavender make terrific companion plants, stimulating each other's growth and improving their flavors as their shared soil is symbiotically enriched.
When life gets stressful, one of the oldest tried and true remedies comes from the calming scent of flowers. Lavender is at the top of that list, and when it's an entire field of lavender it can waft our troubles away with both the sight and aroma. Petaluma residents can see and enjoy such a visage on Chapman Lane where the Lavender Bee Farm has been enchanting locals and international guests for many years.
