This ornamental all year long hardy and vigorous ninebark is popular for its rich dark purple leaves that turn red and bronze tones in fall. It also offers clusters of beautiful ivory flowers that contrast nicely with the leaves.
Ninebark is a hardy deciduous shrub with long-lasting flowers and fruits and exfoliating bark. This tough native of the eastern United States has an informal habit and slowly suckers. In the wild it exists along the fields and forest margins of uplands and lowlands.
The leaves are dark purple and turn shades of red and bronze in fall. In late spring or early summer it bears conspicuous clusters of small creamy flowers that are rosy pink in bud. The flowers are followed by small oval fruits that turn from green to red. After leaf fall its exfoliating brown bark takes center stage.
Ninebark is a durable shrub that accepts most acid to neutral soils, particularly those that are moist and fertile but well-drained. It flowers and develops its best habit in full sun but will tolerate partial sun. Over time ninebark will sucker and spread. Remove the old stems in early spring or prune it back to strong new shoots after flowering. Use this shrub to anchor a native garden or mixed border. It can also be planted in natural areas or roadsides. (info source: Learn2Grow)

| Useful Info | |
| Germination | 1. Soak the seeds in water overnight<br /> 2. Place the seeds in a moist material such as milled sphagnum peat, sterile soil or vermiculite.<br /> 3. Refrigerate the seeds for 2-3 months at 33 to 41 degrees Fahrenheit (+2 – +4C).<br /> 4. After the seeds are stratified, plant them no more than one-quarter inch deep in a container filled with a moist, well-drained germination medium. Cover with glass or plastic and keep the container moist, but not soggy. Seeds should germinate in 3 to 4 weeks at 70 to 75 degrees Fahrenheit bottomheat. As soon as the seeds germinate, place them under bright lights or move them to a greenhouse or cold frame.<br /> Another method is to plant seeds outdoors in well prepared beds in October or before the winter. If it does not rain, then water the seedbeds before the ground freezes. The seeds will naturally receive cold treatment during the winter. The seeds should start to germinate when the seedbed warms up in the spring.<br /> When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter. Plant out in late spring. |
