Description
Nepalese ivy – Hedera nepalensis’Roy Lancaster’
In a nutshell
Nepal ivy, Hedera nepalensis ‘Roy Lancaster’, has polyform foliage, some oblong while others have 2 more or less developed lateral lobes. The leaves are rather broad, dark green to gray-green, and fairly dull. They turn bronze in cold conditions.
In spring, the young shoots take on a light brown color and the leaves are shiny.
This vigorous, branching ivy is best used as a climber, even in the sun.
History
This cultivar was described and named by Peter Q. Rose in 1982. It had been discovered in 1980 by Roy Lancaster at Mount Emei, Sichuan province, China. Among all the Hedera nepalensis plants collected on that occasion, this one stood out for its chocolate-tinted coloration on the young foliage.
