Paraguayan nightshade is commonly cultivated in the warmer parts of the North Id, particularly north of the Volcanic Plateau and is reported to have red frs. The N.Z. plants probably represent cv. 'Grandiflorum', which has fls larger than those described for the wild sp. (Fig. 116). The 10-ribbed calyx with each rib produced into a tooth distinguishes it from all other spp. in N.Z. It has been known previously as S. rantonnetii and Lycianthes rantonnei in N.Z.
