Mrs. R. B. E., Melrose, Mass., asks: " Will some one inform me through the Monthly if Jasminum officinale is hardy in this latitude. Also the winter treatment of Possoquera longiflora. It only grows for a few weeks in the summer, and remains dormant the rest of the time. Should it be kept rather dry, and in a sunny or shady position? Also, at what season does it flower, and how old must it be? Mine is not three years old. Can Dipladenia be grown outside of a hot-house, say in a room where Crotons, Dracenas, Allamandas etc., grow well? They are so very beautiful, I am very desirous of trying them, if there is any probable chance of success".
