A cultivar of Ficus carica L. It was probably brought from Italy by J. H. Vivian Esq. It was grown by Mr. Barron in the greenhouse of his house, ‘Singleton’. A correspondent to 'The Gardeners Chronicle' described it as ‘white, much smaller than Marseille, and prolific as an Orlean plum, every joint of every branch of proper growth being studded with a fruit. I suggested to Mr. Barron to call it the ‘Singleton perpetual’ which name I think it is entitled to bear until we find some prior claim to its introduction. With a score of plants of this fig I should have no fear of producing a dish every month of the year.’ [Gard. Chron. 1855].
