Judging from the graceful appearance which this group of Twiners presents, the natural mistake of supposing that the three flowers an grow upon the same stem might be readily made. This, however, is not the case, and, although a combination of this kind would not be strictly impossible among a particular species, exactness obliges us to say that the subject before us consists of three specimens of distinct varieties, represented, for convenience sake, on the same plate. This artifice, moreover, authorised in similar cases by numerous antecedents, can happily be reproduced in nature, at but little expense, and on a larger scale. It is enough to join on a single lattice-work the slender and trailing stems of the varieties in which the colors harmonize with the greatest effect This is a question of taste, where the difficulties and merit must be left to amateurs. The essential part for the horticulturist is, to furnish the most worthy elements to place in such fancy baskets or groupings. For the purpose, better specimens could not be presented than the three flowers here represented.
The name of Pharbitis Hispida, familiar to botanists, and the only one which they now adopt, designates the old Convolvulus purpureas of Linnaeus, or the common Volubilis of our gardens. It is a plant of American origin, circulated by culture to nearly every point of the globe. The botanist Parkinson cultivated it, in England, in 1625. These flowers, which come five or six together, vary singularly in color, and offer all the shades of white, rose, and violet, and of these mixed.
