Periploca sepium Bunge

Chinese Silk Vine

Modern name

Periploca sepium Bunge

A deciduous climbing shrub 6 to 10 ft (perhaps more) high; young shoots glabrous. Leaves opposite, lanceolate to narrowly oval, not toothed, mostly slenderly pointed, tapered at the base, 134 to 4 in. long, 12 to 114 in. wide, shining green, glabrous on both surfaces; stalk 18 to 12 in. long. Flowers fragrant, about 34 in. wide, produced two to nine together in axillary and terminal cymes during June and July; main flower-stalk 1 to 2 in. long. Corolla greenish outside, dark purple inside, five-lobed, the lobes revolute and woolly towards the margin. Seed-pods in pairs, slenderly cylindrical, tapering at the end where they are connected, 4 to 6 in. long, 316 in. wide; seeds furnished with a tuft of silky white hairs.

Native of N. China; introduced to America in 1905. It differs from P. graeca in its narrower, often lanceolate leaves, more slender stems and somewhat hardier constitution. A further distinction given by Dr Browicz is that the corolla-lobes have a prominent glandular patch on the inner surface near the midpoint, absent in P. graeca.
