My favorite tea herb, Jason!
I allow a few flowers to mature seeds and the tractor guy leaves several to volunteer after tilling. That's worked fine for several years except when I noticed them showing up in the neighbor's raspberry jungle. I am all but certain he will never notice them. Surprisingly, they competed well enough with the raspberries that those anise hyssop plants were there again last year!
I used to walk by a neighbor's garage on the way to my garden. She had lost some perennials in a bed on the north side of the building. I gave her several nice anise hyssop plants to fill in. The next spring, her bed was blanketed in tiny anise hyssop seedlings! That neighbor noticed them ...
My plan is to grow peas again with wheat and oats. The salad vegetables always grow together: onions from sets, spinach, bok choy, lettuce. The later lettuce transplants may go in along the outside of a bed most anywhere. Orach has a home in the potato bed. Those plants also volunteer and I move them around where they can have some room and not be trampled. Dill volunteers quite a few places. It seems to get along fine with the sweet onions - I like to have it around.
