Rhubarb (Rheum rhabarbarum 'MacDonald') - Interesting facts
The leaf blades are poisonous if ingested. The blades have a relatively high concentration of oxalic acid, which gives the leaves their toxicity. Interestingly enough the petioles of the leaves (otherwise known as the stalks of the leaves) do not share the high concentration of the acid and as a result are edible. These are the plant parts that are famously used in rhubarb pie.
