Anyone who has ever grown cabbage or one of its relatives — lettuce, Brussels sprouts, broccoli, rabe, kale, etc. — has most likely had to deal with the unwanted attention of the cabbage butterfly. This plain white (if rather delicate) flutterer may look pretty as it flies around your garden, but it leaves behind eggs that hatch into caterpillars that will happily eat your plants. To avoid this, try planting the mint-like herb hyssop among your cabbage family plants. It’ll draw the attention of most, if not all, of the local cabbage butterflies, so that you won’t have to deal with handpicking many of the caterpillars off your broccoli.
