How many kinds of rhubarb are there?

There are several varieties of rhubarb, but they can be broadly categorized into two main types: culinary rhubarb, which is commonly used in cooking and baking, and ornamental rhubarb, which is grown primarily for decorative purposes. Within the culinary category, popular varieties include 'Victoria,' 'Crimson Cherry,' and 'Rhu-barb.' Each variety can differ in color, flavor, and texture, but all share the characteristic tartness that makes rhubarb a unique ingredient.
