Instead of the solid green leaves of this species, 'Firefly' leafs out in spring with a gold margin on each leaf. As the leaves mature, the gold turns to chartreuse. Culture and other details are the same as the species. PP 11038. Z. 5-7(8)

Extra-large flowers and glossy, deep gree leaves are the draws on this selection from the Skylands Botanical Garden here in New Jersey. It is difficult to avoid superlatives in describing this plant, which many plantsmen consider the best climbing vine. White lacecap flowers appear in late spring or early summer and are beautifully displayed against the glossy, dark green leaves. The leaves fall in late autumn revealing the richly-colored flaking tan bark of the twigs. This vine will attach itself to brick or stone walls or to tree trunks, where it provides four seasons of beauty. Grows well in full sun or considerable shade, though it's at its best with at least a little shade. Z. 5-7(8)
