Premium Features & Solutions

Choose Your Size — Three Options for Every Goal
3 Gallon — Instant Impact: Our most mature, statement-ready specimen. Plant it and step back — the 3-gallon delivers an immediately finished, landscape-ready look that smaller sizes take seasons to achieve. The choice for gardeners who want results now, not later. Ideal for focal points, foundation plantings, and anywhere immediate visual impact matters.

1 Gallon — Landscape Ready: The professional's choice for value and performance. A fully established plant with a mature root system that settles in fast, blooms the first season, and fills its space within 1-2 seasons. The sweet spot between price and performance for most landscape applications.

Premium Quart — Budget-Friendly Starter: The smart choice for mass plantings, hedges, and large-scale projects where cost per plant matters. Same exceptional genetics, vigorous nursery-grown stock, blooms the first season. Order 5-10 quarts with Fill My Box savings and create a stunning golden hedge or woodland border at a fraction of the cost.

The Shade-Blooming Advantage
Most flowering shrubs demand full sun to bloom well. Kerria 'Plenifolia' is the rare exception — it blooms prolifically in partial to full shade, making it the go-to solution for the shaded borders, woodland edges, and north-facing foundations that leave most gardeners frustrated. If you have a challenging shaded area that needs color, this is your plant.

Golden Pompom Blooms — A True Spring Spectacle
The double-petaled flowers of 'Plenifolia' are unlike anything else in the spring garden. Each bloom is a perfectly formed golden-yellow pompom that resembles a miniature rose, covering the graceful arching branches in a cascade of color from early spring through summer. The effect of a mature, established Kerria in full bloom — especially the 3-gallon size — is genuinely spectacular. Sporadic rebloom continues into fall, extending the color season well beyond the primary flush.

Four-Season Landscape Value
Kerria earns its space in the landscape year-round. Spring brings the golden pompom bloom spectacle. Summer delivers lush light-green foliage that stays clean and attractive through the heat. Fall transforms the foliage to bright yellow for a second color moment. Winter reveals vivid green arching stems that provide structure and color in the dormant landscape — a rare quality in a deciduous shrub.

Tough as Nails — Thrives Where Others Fail
Kerria 'Plenifolia' is one of the most adaptable flowering shrubs available. It tolerates poor soils, dry or wet conditions, partial to full shade, and extreme temperatures from -30°F to summer heat. Have a challenging area — dry shade, a slope, a difficult corner, a woodland edge? Kerria will fill the bill where other shrubs struggle or fail. The rapid growth rate means it fills problem areas quickly and decisively.

Mass Planting and Bundling Strategy
Kerria is most spectacular in mass plantings — a drift of 3-5 plants along a fence line, woodland edge, or shaded border creates a golden spring river of color that stops traffic. Use the Fill My Box tiered savings to order multiple plants at 15-25% off. Mix quart and 1-gallon sizes to maximize your savings while creating an immediately impactful planting. For instant hedges or foundation plantings, bundle 3-gallon specimens for a mature, finished look from day one.

Smart Growing Guide

For Beginner Gardeners — Step-by-Step Success:

Step 1: Choose Your Location
Select a spot in full sun to partial shade. Kerria is one of the few shrubs that blooms well in shade — ideal for north-facing foundations, woodland edges, and shaded borders. Avoid waterlogged areas; most well-drained soils work well.

Step 2: Prepare the Planting Hole
Dig a hole twice as wide as the root ball and the same depth. Enrich with organic compost if available. Set the plant so the top of the root ball is level with surrounding soil. Never bury the crown.

Step 3: Plant and Space Correctly
Space plants 4-6 feet apart for individual specimens or 3-4 feet apart for hedges and mass plantings. The rapid growth rate means plants fill their space quickly — don't crowd them. Firm soil gently and water thoroughly after planting.

Step 4: Water Through Establishment
Water regularly during the first season. Once established, Kerria is quite drought tolerant and only needs supplemental water during extended dry spells. The 1-gallon and 3-gallon sizes establish faster than the quart.

Step 5: Mulch for Success
Apply 2-3 inches of organic mulch around the base, keeping it away from the stems. Mulch conserves moisture, suppresses weeds, and moderates soil temperature. Particularly important during the first season.

Step 6: Fertilize in Spring
Apply our SR-18-5-10 slow-release fertilizer in early spring as buds swell. This supports vigorous growth and abundant blooms. Avoid high-nitrogen fertilizers which promote foliage over flowers.

Step 7: Prune After Blooming
Thin branches after the primary bloom flush to maintain shape and encourage vigorous new growth. Remove any dead or damaged wood. Kerria responds well to pruning and can be kept more compact than its natural 6'+ size if desired. Can also be trained as a small tree or espaliered against a wall.

For Advanced Gardeners — Technical Details:

Kerria japonica 'Plenifolia' performs optimally in USDA zones 4-9 with full sun to full shade exposure. Unlike most flowering shrubs, bloom production is not significantly reduced in partial to full shade — making this one of the most valuable shade-tolerant flowering shrubs available. Soil adaptability is exceptional: tolerates clay, loam, sandy soils, dry conditions, and occasional wet periods. Prefers moist, well-drained, organically rich soil for maximum growth rate and bloom production.

The rapid growth rate is a defining characteristic — established plants can add 2-3 feet of growth per season under optimal conditions. This makes Kerria an excellent choice for quickly filling problem areas, establishing hedges, or creating privacy screens. The 3-gallon size provides the most immediate impact and reaches mature size fastest; the 1-gallon is the value-performance sweet spot for most applications.

Flowering occurs on previous season's wood (old wood) for the primary spring flush. Do not prune in late summer or fall as this removes next season's flower buds. Prune immediately after the primary bloom flush in late spring to early summer. Sporadic rebloom on current season's growth occurs through fall. The vivid green stems provide winter photosynthesis and ornamental value — avoid heavy winter pruning.

Suckering habit can be used strategically for mass planting naturalization or managed by removing unwanted suckers at the base. Division of established clumps in early spring is an effective propagation method for expanding plantings. RHS Award of Garden Merit confirms exceptional, reliable performance across a wide range of garden conditions.

Pro Tips for Maximum Impact

• Bundle for Instant Hedges: Order 3-5 of the 3-gallon size for an immediately mature, finished hedge or foundation planting — use Fill My Box to save 15-25% and get professional results from day one
• Mass Planting Value: Order 8+ quart or 1-gallon plants with Fill My Box for 25% off — create a stunning golden woodland border or fence line planting at a fraction of retail cost
• Shade Problem Solver: Use Kerria to anchor shaded borders where other flowering shrubs fail — it's one of the only shrubs that delivers spectacular bloom color in deep shade
• Pruning Timing is Critical: Always prune immediately after the primary bloom flush — never in late summer or fall, which removes next season's flower buds on old wood
• Winter Interest: Position where the vivid green arching stems are visible from windows or walkways in winter — they provide rare color and structure in the dormant landscape
• Companion Planting: Pair with azaleas, hydrangeas, hostas, and ferns for a layered woodland garden that blooms in complementary waves from spring through fall
• Espalier Option: Train against a north-facing wall or fence for a dramatic, space-efficient display — Kerria responds exceptionally well to espalier training

Frequently Asked Questions

Q: What's the difference between the three sizes?
A: The Premium Quart is our budget-friendly starter — best for mass plantings and hedges where cost per plant matters, blooms the first season. The 1 Gallon is our landscape-ready choice — established root system, faster establishment, blooms well the first season, fills its space within 1-2 seasons. The 3 Gallon is our instant-impact option — a mature specimen that delivers an immediately finished, professional landscape look from day one.

Q: How does the Fill My Box savings work?
A: Buy 2 plants and save 15%, buy 4 plants and save 25%, buy 6 or more plants and save 30%. Savings apply automatically at checkout.

Q: Will it really bloom in shade?
A: Yes — this is Kerria's defining advantage. Unlike most flowering shrubs that require full sun, 'Plenifolia' blooms prolifically in partial to full shade. It's one of the best solutions available for shaded borders, woodland edges, and north-facing foundations that need color.

Q: How fast does it grow?
A: Rapidly — established plants can add 2-3 feet per season under good conditions. This makes it excellent for quickly filling problem areas, establishing hedges, or creating privacy screens. The 3-gallon size reaches mature size fastest.

Q: When should I prune it?
A: Prune immediately after the primary bloom flush in late spring to early summer. Never prune in late summer or fall — Kerria blooms on old wood, and fall pruning removes next season's flower buds. Light shaping can be done at any time to manage size.

Q: Will it bloom the first year?
A: Yes. All three sizes bloom the first season after planting. The 3-gallon delivers the most impressive first-season bloom display due to its mature size and established root system.

Q: Is it deer resistant?
A: Yes. Kerria is naturally deer resistant, making it an excellent choice for landscapes with heavy deer pressure.

Q: How big will it get?
A: Naturally 6'+ tall and wide, but it responds very well to pruning and can be maintained at a smaller size. It can also be trained as a small tree or espaliered against a wall for a more controlled, architectural effect.

Q: What are the best companion plants?
A: Azaleas and rhododendrons create a stunning spring bloom combination. Hydrangeas extend the flowering season into summer. Hostas and ferns provide complementary texture in shaded settings. All share similar partial-shade preferences and create a layered woodland garden effect.

Q: Does it have any winter interest?
A: Yes — the vivid green arching stems remain colorful and ornamental throughout winter, providing rare structure and color in the dormant landscape. This four-season interest makes Kerria an exceptional landscape value.
