Pachysandra terminalis

Description

Appearance & Growth Habit

• Evergreen, mat-forming perennial in the boxwood family (Buxaceae), native to Japan, Korea, and China.

• Grows to about 10 cm (4 in) tall and spreads roughly 60 cm (2 ft) wide, creating a lush groundcover.

• Leaves are leathery, glossy, and toothed, typically around 5–10 cm long.

• Small white flowers arise just above the foliage in spring (March to April in temperate Northern Hemisphere) on short spikes.

Cultivars & Varieties

• Popular forms include:

  • ‘Variegata’ (Silver Edge) – leaves edged with creamy white; slower spreading.

  • ‘Green Carpet’ – compact, glossy foliage, matting habit.

  • ‘Green Sheen’ – extra glossy, slow-spreading variety.

Growing Conditions & Use

Ideal Environment

• Thrives in partial to full shade, making it excellent for shady spots like under trees or shrubs.

• Prefers moist, well-drained soils, tolerant of a wide range—from acidic to alkaline, from loam to clay.

• Hardiness zones: USDA 4–9 (even occasionally zone 3), RHS H5—meaning it withstands cold winters.

Benefits

• Low maintenance and deer- and rabbit-resistant, making it a resilient choice.

• Excellent for weeds suppression, erosion control, and underplanting in shade gardens, woodland areas, slopes, or courtyards.

• Generally problem-free, though slugs, snails, or occasional fungal issues (e.g. Volutella blight) may arise.

Caution: Invasiveness

• Spreads via underground rhizomes, forming dense carpets that may smother native plants.

• Considered invasive in some U.S. regions (e.g. Virginia and Washington, D.C.).

• Gardeners on Reddit note its aggressive nature:

  “Pachysandra spread via underground rhizomes… any piece… left behind can grow into a new plant.”
