My dad always said, "If you can't have your own garden, cultivate a friendship with a gardener. " You've got a good deal with your own gardener! : ) And it's nice that your son is appreciating some fresh-grown herbs, especially some of the unusual ones, like anise. Folks that have access to community gardens really should be more aware of Poison Hemlock. There's really a 2-sided lesson. One side is that not everything growing in a garden is OK to eat, like rhubarb leaves or potato tops, or poison hemlock. The other side is that some weeds are as good to eat as anything people are trying to grow.
