Aralia Sun King
Aralia cordata Sun King
Sun King Aralia is one of the best plants for making a shaded bed feel brighter and more intentional. The golden foliage has real presence, the mature plant can anchor a border like a shrub, and deer usually leave it alone compared with many softer shade plants. Give it rich soil and steady moisture, and it becomes a standout focal point for woodland gardens, hosta beds, and shaded foundation plantings.

A Bold Golden Foliage Perennial for Shade Gardens and Woodland Beds
Big Golden Leaves That Light Up Shady Spaces
Sun King Aralia is a dramatic foliage perennial grown for its large chartreuse-to-gold leaves and bold, shrub-like presence in shade and part-shade gardens. This standout plant brings a bright tropical look to woodland beds, shaded borders, and mixed perennial plantings where darker green foliage can feel heavy or flat.
Unlike smaller shade plants used mainly as ground-level fillers, Sun King Aralia creates height, structure, and a true focal point. Its broad compound leaves emerge bright and luminous, holding their best color with part shade and a few hours of gentle sun. It is an excellent choice for gardeners who want a shade perennial that feels bold, fresh, and architectural.
Golden Foliage with Late-Season Flowers and Berries
The main attraction is the foliage, but Sun King Aralia can also produce airy clusters of small white flowers in mid to late summer. These blooms add a soft seasonal touch above the leaves and may be followed by dark purplish to black berries that bring additional interest later in the season.
Foliage color can shift with the light. In brighter part shade, the leaves tend to hold stronger gold and chartreuse tones. In a heavier shade, the color may become more lime green, while too much hot, direct sun without moisture can stress the plant. This makes site selection important for the best color and performance.
A Strong Anchor for Woodland Gardens, Shade Borders, and Mixed Beds
Sun King Aralia works beautifully as a middle-to-back border plant, a woodland garden anchor, a shade garden focal point, or a bold companion to hostas, ferns, heuchera, astilbe, ligularia, brunnera, and dark-leaved perennials. Its size and color help create contrast, especially in beds where many plants have finer texture or deeper green foliage.
Use it as a single specimen when a single bright focal point is needed, or repeat it within a larger shaded border for rhythm. Because it can grow into a large perennial clump, give it room to mature. It is especially useful near shaded patios, woodland paths, foundation beds with morning sun, and garden corners that need height without a woody shrub.
Deer Resistant, Pollinator Friendly, and Best with Consistent Moisture
Sun King Aralia is generally considered deer resistant, making it a valuable option for shade gardens where deer often browse hostas and other tender foliage plants. Deer resistance can vary by location and pressure, but this plant is a strong, lower-risk choice when gardeners need bold foliage in challenging landscapes.
Its summer flowers can attract pollinators, and the berries may provide seasonal interest for birds. This plant is not drought-tolerant, so it performs best with consistent moisture in rich, well-drained soil. For the best results, treat it like a lush woodland perennial rather than a dry-shade survivor.
Easy Care with Part Shade, Rich Soil, and Room to Grow
Plant Sun King Aralia in part shade to light shade with moist, organically rich, well-drained soil. It can tolerate some sun if moisture is consistent, but it should be protected from hot, dry afternoon conditions. Adding compost at planting helps support the deep, rich soil conditions this perennial prefers.
Water regularly after planting and continue watering during dry spells, especially in the first growing season. Sun King Aralia dies back to the ground in winter and re-emerges in spring, quickly building size as temperatures warm. Cut old stems back after frost or in early spring before new growth appears.

How to Care for Aralia Sun King
Be sure to read our planting instructions to ensure a healthy and happy Sun King Aralia for years to come!
How should I plant Sun King Aralia?
Plant Sun King Aralia in part shade to light shade with rich, moist, well-drained soil. Choose a location where the plant has room to reach its mature size without crowding smaller perennials. Morning sun or filtered light is ideal, especially if the soil stays evenly moist. Dig a hole about twice as wide as the root ball and just as deep. Set the crown level with the surrounding soil, backfill with native soil blended with compost, and water thoroughly. Mulch around the plant to help conserve moisture, but keep mulch away from the crown.
How often should I water Sun King Aralia after planting?
Water Sun King Aralia deeply after planting, then keep the soil consistently moist while the roots establish. During the first growing season, check the soil often and water when the top few inches begin to dry, especially during warm or windy weather. This plant is not drought-tolerant, so established plants may still need supplemental water during dry periods. Consistent moisture helps support larger leaves, better color, and a fuller shrub-like habit. Avoid soggy soil, but do not allow the plant to dry out for long stretches.
When should I fertilize Sun King Aralia?
Fertilize Sun King Aralia in spring, if needed, with compost or a balanced, slow-release fertilizer. It performs best in rich, organic soil, so an annual compost topdressing is often a good way to feed the plant gently while improving soil quality. Avoid overfertilizing with high-nitrogen products, which can encourage overly soft growth. The goal is steady, healthy foliage production in moist soil, not forced growth.
When and how should I prune Sun King Aralia?
Prune Sun King Aralia after frost has blackened the stems in fall or in early spring before new growth emerges. Cut the old stems back close to the ground, since the plant dies back in winter and returns from the crown in spring. During the growing season, pruning is usually minimal. Remove damaged stems as needed, and give the plant enough room so it can develop its natural full shape. If mature clumps become too large, divide carefully in spring as new growth begins.
