You might be surprised to see yellow in the winter garden, but several so-called evergreen plants also sport some yellow foliage; i.e., the green and yellow-spotted Aucuba japonica cv. Variegata (Japanese Aucuba), a rosette of yellow Ilex leaves (Holly species) and the yellow needles of Cephalotaxus harringtonia cv. Korean Gold (Japanese Plum Yew). Incidentally, Cephalotaxus is a good, deer-resistant substitute for Taxus baccata (English Yew).
