Rhubarb cultivars have gained the Royal Horticultural Society’s Award of Garden Merit:- "Rhubarb" originally comes from the two Greek words for rhubarb. "Rheon" from the Persian "rewend", later became the Latin word "rheum", meaning rhubarb. The other Greek word is "rha", an ancient name for the Volga River in Russian, where rhubarb was cultivated, having been introduced there from China via the Silk Road. In medieval Latin, "rheon" and "rha" became "rheum barbarum", literally "foreign rhubarb" or "strange rhubarb", and evolved later into "rheubarbarum". Most likely, the English word "rhubarb" entered the language via the French word "rhubarbe" brought over by
Latin obscenity from Latin "cauda/cōda" "tail". The Portuguese "penis", first attested in the 10th century, is thought to derive from a vulgar Latin word "*caraculum" "a little stake". The Italian "" has no obvious Latin ancestor. A number of different suggestions have been made for its origin, but none has yet gained general acceptance. The basic word for the testicles in Latin was "cōleī" (singular: "cōleus"). It appears to have had an alternative form *"cōleōnēs" (singular: "cōleō"), from which the Spanish "cojones" and other Romance forms are derived. (One late Latin source has the spelling "culiones"). The etymology of "cōleī" is obscure.
