Pachysandra terminalis (Japanese Spurge)

Japanese Spurge is a slow-growing shrubby, evergreen ground cover which grows 10-15cm high and spreads by rhizomes to create a heavy carpet of rich, dark green foliage. The plant has oval leaves and it consists of tiny white flowers 2.5-5cm long, terminal, as shown on the photo, spikes bloom in early spring. Flowers are not exceptionally showy, but on the closer look are quite attractive. Best grown in medium moisture, well-drained soil in part shade to full shade. Foliage tends to bleach when grown in too much sun. 

Pachysandra terminalis forms large colonies of roots underground and spreads very fast. Leaf blight is a potentially serious problem which can necessitate remedial fungicide applications.
