One of the Francos' more intriguing plants is Lemon Vine (Pereskia aculeata var. 'Godseffiana'), believed to be very closely related to the 50-million-year-old ancestors of modern cacti. An attractive woody vine that can reach 30-40 feet in height, the plant is grown mainly as an ornamental, likes shade, and produces fragrant white flower clusters in late summer and early fall. Its succulent leaves are a highly nutritious food for livestock and its fruit, the Barbados Gooseberry, is said to be delicious and highly nutritious.
