The native plants may be divided into 4 subspecies, although there is a considerable overlap in most characters. Plants escaped from cultivation are mostly referable to subsp. (d) in the Mediterranean region and to subsp. (a) elsewhere, but some of them cannot be referred to any subspecies, and are perhaps of hybrid origin.
