Pachysandra // is a genus of four or five species of evergreen perennials or subshrubs, belonging to the boxwood family Buxaceae. The species are native to eastern Asia and southeast North America, some reaching a height of 20–45 cm (7.9–18 in), with only weakly woody stems. The leaves are alternate, leathery, with an entire to coarsely toothed margin, and are typically 5–10 cm (2.0–3.9 in) long. The small uni-sexual blooms are greenish-white and produced in late spring or early summer.
The name is derived from the Greek words pachys ("thick") and andros ("male") which is a reference to the thick stamens (the male portion of the flower).

Cultivation and uses
Pachysandra can grow in deep-shade areas and is thus well-suited and popular as ground cover for shade gardens. The most commonly used species is P. terminalis, the Japanese spurge, which is an aggressively spreading evergreen ground cover. The form 'Variegata' has leaves attractively variegated green and creamy white, and is slightly less invasive. All species in this genus prefer a well-drained soil with a high humus content.
