Let’s do a quick recap, because I know your eyes are glazing over. Rhubarb: thick, sour, toxic leaves, sweet recipes only. Swiss chard: tender, mild, eat everything (leaves and stems), savory dishes. One grows like a grumpy perennial, the other like a generous annual. If you still mix them up, just remember: rhubarb will make you pucker, chard will make you dinner.
So next time you’re at the farmers’ market or staring at your garden, give the stalk a little squeeze. If it whispers, “pie,” it’s rhubarb. If it whispers, “sauté me with garlic,” it’s chard. And if your neighbor shows up with a fistful of chard stems and a pie crust bent on disaster? Send them this article. You’re welcome.
