Hedera rhombea
Japanese ivy
An evergreen climbing shrub with dark green, three-lobed foliage with prominent grey veining. Possibly, insignificant yellow-green flowers may appear in the autumn, following by round, black fruits. This species is native to Japan and Korea, and is a little more distinctive and attractive than some of our native UK hederas
