Japanese Ardisia

The Story

Plant Bio

Ardisia japonica is a low stoloniferous evergreen subshrub from eastern temperate Asia that spreads by underground runners to form dense colonies 8 to 12 inches tall. Stems carry thick glossy elliptic leaves concentrated near the branch ends, with white to pale pink five-petaled flowers in small axillary clusters followed by red drupes that darken through fall.

Unlike coralberry Ardisia crenata, which builds an upright shrub to six feet, this species stays under a foot and spreads sideways by suckers and self-sown seed to make a tight groundcover. Its foliage burns in full sun and holds best in part to full shade in acidic humus-rich soil that stays moist but never waterlogged.

Uses & Benefits:

Dense glossy evergreen groundcover for deep shade with pale flowers and red to black berries that persist into winter.

Fills moist shade where turf fails and covers soil under trees where foot traffic is absent.

Persistent drupes provide cool-season food for birds; dense colonies shelter ground fauna.

Planting

How to Grow

Plant in spring in part to full shade in acidic, humus-rich soil that drains freely.
Set plants 12 to 18 inches apart to allow runners to fill in, keeping the crown at soil level.
Water deeply after planting and keep soil evenly moist through the first summer.
Spread 2 inches of pine bark or leaf mulch to hold moisture and keep foliage off bare soil.

Pro Tip

Plant it only where suckering spread is acceptable, and pull unwanted suckers and seedlings in spring before colonies knit together.

Care Guide

Do

Grow in part to full shade with protection from afternoon sun
Keep soil evenly moist with organic mulch
Divide congested patches or take cuttings in summer to increase stock

Don't

Don't plant in full sun where leaves scorch
Don't plant in waterlogged soil or where water stands after rain
Don't plant next to delicate perennials if you cannot allow suckering spread
