Some flowers – such as marigolds – are a kind of ‘wonder’ flower, keeping a host of hungry beetles, aphids, and nematodes away from your flowers and vegetables, while perhaps even helping them grow bigger and stronger.

For example, dill seems to improve the flavor of anything in the cabbage family, from Brussels sprouts, to cabbage, to kohlrabi; basil and tarragon boost the flavor of almost any veggie you might plant near it; chives help carrots, tomatoes and peas and also discourage a host of hungry bugs.

Pole beans are a bit fussier, enjoying the company of corn, marigolds, potatoes, and radishes. Swiss chard, though, doesn’t care for pole beans or onions. You can plant your tomatoes near your asparagus, basil, cabbage family, carrots, gooseberries, mustard, parsley, onions, rosemary, and sage,
