In landscaping, ninebark is used for specimen planting, foundation planting, hedges, screens, and to prevent erosion on slopes.

Ninebark Varieties

Physocarpus opulifolius is a member of the rose family, including hawthorns, spirea, and several fruit shrubs and trees. The shrub is found naturally in abundance across the eastern United States, stretching West into the Dakotas and south to northern Florida.

Also, one type is found in the Rocky Mountains and westward to Oregon and Washington. The ninebark shrub comes in several varieties with colored leaves, commonly purple and yellow. Here are those varieties:

Diablo or Monlo

Little Devil or Donna May

This is a dwarf variety, 3 to 4 feet tall with greenish burgundy foliage. It blooms in early summer and is known to have good resistance to mildew. It's hardy in zones three through seven.

Center Glow

This is one of the more colorful varieties. It's a 6 to 8 feet tall shrub with spring flowers of greenish gold that gradually mature to deep burgundy red in summer. It blooms with white flowers in late spring and is hardy in zones 3 to 7.

Dart's Gold

Dart's gold is bright yellow in spring, then matures into deep chartreuse in summer. In fall, the leaves develop a tinge of bronze. White flowers appear in late spring. This variety grows 4 to 5 feet tall and is hardy in zones 3 to 7.

Planting Ninebark

Dig a hole as deep as the container holding your ninebark, and twice as wide. Plant the shrub so the top of the root ball is exactly at ground level, then fill around the root ball with soil, ensuring there are no air pockets. Poor soil can be amended with organic material before filling in soil. Water well until the plant is established.

Care for Ninebark


Ninebark grows best in full sun but can tolerate partial shade. In the northern part of its growing range, the shrub prefers around six hours of direct light each day, but the farther south it grows, the more it appreciates some afternoon shade.


Ninebark prefers neutral to slightly acidic soil that is well draining, but it will tolerate slightly alkaline soils. Mulch can help to retain moisture and hold down weeds. As its native habitat includes stream banks, hillsides, and damp thickets, ninebark tolerates clay and loam soil, as well as shallow and rocky soil. Although it prefers evenly moist, well drained soil, it’s adaptable to rocky and clay soils.


Ninebark will grow in both dry and wet locations. Its water requirements are generally low, but it will handle poor drainage and occasional flooding if necessary. Once established, ninebark is a good drought tolerant shrub for dry areas.

Temperature and Humidity

Ninebark prefers cool weather as its native habitat is at high elevations in the mountains. It is hardy to USDA plant hardiness zone 2 to 7, meaning it can withstand winter temperatures as low as −40 °F (−40 °C). Ninebark is also tolerant to various humidity levels within its recommended hardiness zones.

However, this shrub doesn't like hot and humid climates, which can cause fungal diseases in the plant, such as powdery mildew.


Ninebark is not a heavy feeder. Ninebark prefers soil with a pH of 6.5 to 7.0, so adding lime can be useful in acidic soils. Although ninebark doesn't need fertilizer very often, if the soil isn't fertile, it will perform better with regular fertilization twice a year during its active growth.

Once you know how to easily make compost and organic plant food for shrubs and trees, use them to fertilize the ninebark. Apply the fertilizer into the soil starting a few inches away from its trunk and out to where its branches end.

Pruning Ninebark

You should prune ninebark at least once a year early in the growing season. The best time to prune the ninebark shrub is in the first few days after it flowers, which happens between the late winter and early summer, depending on your location. Pruning will help maintain its shape, thin out the shrub, and improve air circulation.

Fully one third of the branches can be cut out with each pruning. Focus on older branches, damaged branches, and those that cross and rub. For winter, older shrubs can be radically pruned close to the ground to renew the plant and encourage better leaf and flower growth. Ninebark tends to back well after pruning.

Propagating Ninebark

Woody shrubs can be tricky to propagate and it can take quite a while, but many people find that stem cuttings from ninebark are relatively easy to root. Unlike herbaceous plants, where cuttings must have leaves, with woody plants like ninebark, the cuttings should be taken when the plant is in dormancy.

Other methods of propagating ninebark, such as layering, are bending down one of the flexible branches so a portion is buried in the soil, with the tip of the branch exposed. When secured in place, the buried portion will send out roots from nodes on the branches.

Once the branch has developed ample roots, which can take a full growing season, you can snip it off the mother plant and then dug up the rooted cutting to replant elsewhere.

Common Pests and Diseases

When kept vigorous, ninebark physocarpus can be free on most problems. Fire blight, powdery mildew, and leaf spots may occur but are rarely fatal. You can also prune away the badly damaged branches.

The plants can be susceptible to aphids, which you can control by spraying with water to knock them offor by spraying the shrub with neem oil or another organic spray.
