chamomile is a must imo, good for your plants, good for the soil, good for you, good all around. self seeds once you plant it and let it go to seed. grows without care in moderate climates, needs water in hot climates with bare soil and no shade.
yarrow is also a must, go for the white wild yarrow if you can. its the best, but the colored cultivars provide more of a show while giving you ferts. some of the cultivars are more vigorous too, so you get more biomass out of them. i only use the wild yarrow for medicinal purposes.
