Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 139. Flower of Dutchman's Pipe, Aristolochia macrophylla. Showing the ovary at a, and the swelling of the calys-tube at &. Natural size. The best known representative of this genus is Aris- tolochia niacrophylta (or A. Sipho), the "Dutchman's Pipe," than which there is no better hardy climbing vine for shade or screen purposes. No insects or other trou- bles seem to mar its deep green foliage, for which it is most valued, as the fls. are small, siphon-shaped, and inconspicuous, in early spring soon after the Ivs. are formed. There are many tropical Aristolochias, the fls. of some of them being of extraordinary size, structure, and odor, but they are rarely seen on account of the last â characteristic, the odor being so suggestive of putridity as to make its proximity apparent to all, and even to deceive the flies as to its origin. One of the most gi- gantic varieties is A. grandiflora, var. Sturtecantii. Another fine species is A. Goldieana; but the best of the tropical kinds for general culture in glass structures is A. elegans, as it is very easily raised from home- grown seeds, flowers the first year, is very decorative as a climber, and has no odor. We find it very easy of culture in rich soil, and it is evergreen, as, indeed, are most of the tropical kinds. The Aristolochias are of easy culture, requiring only good loam and careful attention to keep them thrifty and free of insects. They can be trained on trellises, pillars, or rafters. Most of them require a rather warm temperature, but if in pots they may be flowered in the conservatory. The large-growing species require much room, and do not bloom, as a rule, until they are several feet high. Prop, readily by c
