Rhubarb (Rheum rhabarbarum)

Plant once, harvest for decades — but only the stalks

🔍 How to identify it

Huge crinkled triangular leaves on thick red-to-green stalks from a crown; towering cream flower spike if it bolts. Unmistakable rhubarb-pie tang in the stalk.

☠️ Look-alike & safety

⚠️ The LEAF BLADES are toxic (oxalic acid) — eat only the stalks. Nothing to confuse it with.

Plant identification here is educational — never eat, forage, or medicate with a wild plant on the basis of a website alone. Many edible plants have toxic look-alikes. When in doubt, grow from known seed, or confirm with an expert before you harvest.
