They are both, beautiful, with their mostly large and delicate, tender flowers, and also an annoying weed in gardens and lawns, which is hard to control.Convolvulus elegantissimus is a Mediterranean plant of dry and sunny places growing in all Mediterranean countries and Macaronesia (the four archipelagos Azores, Madeira, Canary and Cape Verde islands). The only exception is Slovenia. However, the plant is quite common in neighborhood in Croatia along Adriatic Sea coast and islands.Its taxonomy is not yet settled. Some authorities know it under the name Convolvulus althaeoides, some consider it as a subspecies of it (Convolvulus althaeoides subsp. elegantissimus), others consider it on species level as Convolvulus-elegantissimus (for example Catalogue of Life (2017), Ref.3). Convolvulus-elegantissimus should differ from Convolvulus althaeoides s.str. in palmate, deeply lobed leaves (just to the base of the leave) with narrow lobes and appressed hairs all over the plant. They often look silvery-grayish because of abundant hairs. Such plants are considered more frequent in east Mediterranean regions.Ref.:(1) M. Blamey, C.
