Ninebark Coppertina

Physocarpus opulifolius 'Coppertina'

shrub

Coppertina is a deciduous ornamental shrub prized for its striking foliage that transitions from deep copper-red in spring to burgundy in summer and orange-red in fall. It produces delicate pink and white flower clusters in late spring, followed by decorative seed pods. This cultivar is a compact, mounded form of ninebark that works well as a foundation plant or accent in mixed borders.

Growth Stages

Transplant/Establishment

4-8 weeks

Young plant establishing roots after transplanting; initial growth is modest with new shoots emerging

Water regularly to keep soil evenly moist (not waterlogged) for first 6-8 weeks. Avoid fertilizing. Mulch around base leaving 2-3 inches from stem.

Vegetative Growth

Spring through early summer (8-12 weeks)

Shrub develops branching structure with multiple stems; foliage exhibits copper-red coloring in spring, transitioning to burgundy

Prune in late winter/early spring to shape and encourage fuller growth. Remove dead or crossing branches. Fertilize lightly in spring if desired.

Flowering

4-5 weeks (typically May-June)

Delicate clusters of small pink and white flowers appear at branch tips; flowers attract pollinators

No specific care needed. Deadheading not necessary but optional. Flowers are self-cleaning.

Fruiting/Seed Pod Development

Summer through winter

Small decorative seed pods develop after flowers fade; pods persist into fall and winter, providing ornamental interest

Leave seed pods intact for visual appeal and wildlife food source. No pruning during this stage unless removing damaged growth.

Dormancy

November-March

Foliage drops in fall after turning orange-red; bare branches with persistent seed pods visible through winter

Reduce watering significantly. Prune in late winter (February-March) before new growth emerges. Clean up fallen debris if desired.

Companion Planting

Plant with:

Coreopsis Russian Sage Sedums Ornamental Grasses (Panicum, Miscanthus) Boxwood Serviceberry Daylilies Butterfly Weed

Avoid planting near:

Black Walnut (Juglans nigra) - produces juglone toxin Competitive shallow-rooted shrubs in very confined spaces

Common Pests

Prune out affected branches; apply insecticidal soap in early summer if severe; encourage natural predators
Ensure good air circulation; avoid overhead watering; apply sulfur fungicide if necessary; resistant cultivar selection helps
Spray with water to dislodge; apply neem oil or insecticidal soap if population is high; increase humidity
Remove affected leaves; improve air circulation; avoid overhead watering; apply fungicide if widespread

Uses

🌿

Foliage Color & Seasonal Interest

Ornamental

Provides exceptional multi-season color with copper-red spring foliage transitioning to burgundy summer growth and orange-red fall tones. The persistent seed pods add winter interest. [source]

🦋

Pollinator & Bird Support

Wildlife

Flowers attract bees, butterflies, and other pollinators in spring. Seed pods provide food for birds in fall and winter. [source]

🏠

Landscape Design & Hedging

Household

Excellent for foundation plantings, mixed borders, mass plantings, and informal hedges. Compact mounded form makes it ideal for small to medium landscapes. [source]

🎨

Cut Flower Arrangements

Craft

Branches with flowers and foliage are attractive in fresh arrangements; dried seed pods can be used in fall and winter dried arrangements. [source]

Harvest Tips

Not a harvested plant for edibles. Branches can be cut for fresh or dried flower arrangements in late spring; cut from mature plantings to avoid overpruning.

Fun Facts

🌱 The common name 'Ninebark' refers to the exfoliating bark that peels in layers—ninebark shrubs can have up to 9 thin layers of papery bark peeling away, creating a striped appearance on older stems.
🌱 Coppertina was selected and introduced as a cultivar specifically for its enhanced reddish foliage compared to the species, making it a modern garden favorite for color-focused landscaping.
🌱 This shrub is native to eastern North America and is extremely cold-hardy, surviving winters in zones as cold as zone 2 where temperatures drop below -40°F.
