Pandorea (Pandora, Greek mythological name). Bignoniaceae. Ornamental woody vines grown for their beautiful flowers and also for their handsome foliage.
Evergreen shrubs climbing without tendrils or roots: lvs. opposite, odd-pinnate; lfts. entire or serrate: fls. in axillary or terminal few- or many-fld. panicles; calyx small, campanulate, 5-toothed; corolla funnelfonn- campanulate, with imbricate lobes; stamens included, with spreading superposed anther-cells; disk thick, ring-like; ovary linear, the seeds in many series: pod oblong, with thick not keeled valves; seeds broadly elliptic, winged.—Five species from Austral, to Malay Archipelago and in S. Afr. Formerly usually included under Tecoma.
The pandoreas are vigorous-growing vines or lianas with handsome evergreen foliage and beautiful white or pink rather large flowers. They can be grown outdoors only in the southern states and in California and stand few degrees of frost; in the North they are sometimes a cultivated in the greenhouse. They require rich soil and sunny position. Propagation is by seeds and by greenwood cuttings under glass. See also Bignonia for culture.
The wonga-wonga vine, P. australis, is rather difficult to grow on high pine-land, as it needs a soil rich in humus. In rich soil, however, and liberally fertilized, it is a rampant grower with beautiful dark green glossy foliage. The flowers are interesting but comparatively small, and not showy. However, the species is worth cultivating for foliage alone. It must be well taken care of and well watered during the dry spring months or it will dwindle away in a very short time.
P. Ricasoliana, from Natal and Caffraria, demands a very rich soil and a heavy mulch of stable manure. Its leaves easily drop from the woody branches after a cold night, and 6 or 7° of frost kill the plant down to the ground. For this reason the vine should be banked with dry sand every fall and if killed down to the banking it must be cut off immediately or the entire plant will be lost. Plants raised from seed received under the name of Tecoma Ricasoliana, from Italy, are much hardier and more floriferous than those obtained from seed imported from South Africa, but the flowers of both are exactly alike. In order to flower profusely, this species must be planted in the full sun. It usually requires a few years before it starts into a vigorous growth, and it rarely flowers before its fifth year or before it has attained considerable size. In Florida, P. Ricasoliana should be planted on tall stumps, or on arbors and sheds by itself, never mingled with other species. (H. Nehrling.) CH
