This combination in one of our raised beds was from 3 years ago. We planted scented geraniums at the near end of this bed around the sweet potatoes, and nasturiums at the far end behind the squash and sunflowers. We had a great crop from all.
This bed held artichoke and dill, along with onions.
We have also planted our blueberry bushes in the perennial beds. Now after reading your article I will be planting even more eatables in the the perennial borders. You have me all excited about trying this.
