Dipladenia is one of the- modern favorites in the list of conservatory climbers. The Gardener's Record thinks too much prominence cannot be given to it; for, "like many climbing plants, it blooms best when grown prominently forward near to the glass, and perhaps to perfection near to the roof of an intermediate house, with general temperature not below about 55°. Dipladenias are natives of Central America, and belong to the order of Dogbanes, a name given by Dr. Lindley to a certain class of plants, which I believe Linnaeus described as having contorted or twisted-like flowers, with corollas resembling a cathe-rine-wheel firework in motion. To this family belong the Periwinkle, the Oleander, etc. With twining habit, and large graceful flowers nearly five inches in diameter, in form like a Convolvulus, and with color varying from pale pink or French white, to clear delicate rosy pink, I know not any more lovely climbing plant for summer, and what is commonly called early autumn. It may be grown from layers, from cuttings, and from seed.
