Sun King Golden Japanese Spikenard

Sun King Golden Japanese Spikenard (Aralia cordata 'Sun King')

Sun King golden Japanese spikenard is a bold shade perennial that lights up darker garden spaces with glowing gold foliage. It grows fast into a full, shrub-like clump each season, giving you big texture without a woody plant. The color stays strongest with a bit of sun, but it still brightens deep shade with a softer chartreuse tone. If you want an easy anchor plant that makes a shady bed look intentional, this is a dependable choice.

Distinctive Features

This herbaceous perennial produces large, compound leaves in vivid gold on contrasting stems, creating a tropical, high-impact look in temperate gardens. In late summer, airy clusters of tiny white flowers rise above the foliage and can be followed by dark purplish black berries. The habit is upright and clumping rather than running, so it fills space in a controlled way. Once established, it is durable and long-lived, especially in soils that stay evenly moist but drain well.

Growing Conditions

• Sun: Part shade to shade, with brighter foliage color in morning sun or filtered light.
• Soil: Moist, fertile, humusy, well-drained soil, and avoid sites that stay soggy.
• Water: Medium water, keeping soil consistently moist during establishment and summer heat.
• Zones: USDA Zones 3 to 9.
• Mature Size: Typically 3 to 4 feet tall and 3 to 4 feet wide.

Ideal Uses

• Focal Point: Plant as a bold gold anchor in a shady border where the foliage becomes the main visual punch all season.
• Shade Borders: Adds height and structure behind hostas, ferns, and other woodland perennials.
• Foundation Plantings: Softens shaded walls and corners with big texture and steady color.
• Woodland Gardens: Works beautifully in layered plantings where foliage contrast is the goal.
• Containers: Makes a dramatic, full centerpiece in a large pot placed in bright shade.

Low Maintenance Care

• Watering: Water regularly the first season, then maintain even moisture during drought for best size and color.
• Pruning: Cut stems to the ground in late fall after frost or in early spring before new growth.
• Feeding: Top-dress with compost in spring to support strong growth without pushing weak, floppy stems.
• Mulching: Mulch to conserve moisture, keeping mulch a few inches back from the crown.
• Wind Protection: Site out of strong winds to protect the large leaves from tearing.
