Of the shrubby, sprou ting-leaf species none is more curious than the Air Plant. B. tubiflorum, whose tubular green and brown leaves bear innumerable plantlets at their tips and a wealth of orange-red flowers in winter. Equally prolific and beautiful are the species B. crenatum and B. fedtschenkoi, which have small, rounded, frosty-green leaves suffused pinkish red, and red flowers in winter. A very showy species with large arrow-shaped leaves, green spotted brown, is B. daigremontianum, whose numerous plantlets and yellow and pink winter flowers have made it extremely popular.
Aside from these sprouting-ieaf species one must not overlook two bryopiyllums which are noted for their strong climbing and trailing habit. B. scandens is a very interesting climber whose curious foliage and flowers can only be described as "mouse-colored"; and B, unifiorum, a wonderful hanging-basket plant with small green leaves and dainty red spring blossoms that have been aptly dubbed Chinese Lanterns.
All members of the Kalanchoe tribe are easily grown and propagated, with no special requirements except protection from frost in winter, hey are excellent pot plants indoors, where their bright winter flowers and interesting foliage are greatly appreciated As house plants they do best in full sunlight, but when planted out of doors they seem to prefer light shade at least part of the day. The florists' kalanchoes are usually treated as annuals and propagated for winter bloom by seed sown in early spring. Other species are propagated by stem cuttings, leaf cuttings, or by plantlets formed on the leaf margins, as tn the genus Bryophyllum.
