Darkstar Ninebark
Darkstar Ninebark
A Native Shrub With Dark Burgundy Foliage and Four-Season Interest
Darkstar Ninebark (Physocarpus opulifolius 'Darkstar') is a tough Minnesota-native shrub grown for its rich, deep burgundy-black foliage that holds color all season, clusters of white-to-pink spring flowers, red seed heads, and handsome exfoliating bark for winter interest. Adaptable, drought-tolerant, and deer-resistant, it's a bold, low-care anchor for sunny borders and foundations in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Dark foliage anchor: Its deep burgundy leaves provide season-long contrast in borders and foundations. Space 4–6 feet apart.
Native, pollinator, and four-season interest: Spring flowers feed pollinators, red seed heads follow, and exfoliating bark adds winter texture. Pair with gold-foliage shrubs and native perennials.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall (late August–mid September). Very adaptable; water through establishment.
How to Plant Darkstar Ninebark
Dig a hole twice the root ball width at the same depth, mixing in compost. Set the crown level, backfill, water well, and mulch 2–3 inches deep. Space 4–6 feet apart. Full sun gives the darkest foliage.
Watering Darkstar Ninebark
First year: Water deeply every 2–3 days at first, then weekly. Stop 2–3 weeks before the ground freezes.
After year one: Drought-tolerant — water during dry spells. Prune after flowering to shape, or cut back hard to renew if it gets leggy.
Q: Is it native?
Yes — ninebark is a Minnesota native, and Darkstar is a dark-leaved selection valued for foliage and wildlife.
Q: Will it survive a Minnesota winter?
Easily — hardy well below Twin Cities lows.
Q: What is the winter interest?
Its bark peels in papery layers (the "nine bark"), adding texture to the winter landscape.
Q: Is it deer-resistant?
Yes — deer rarely browse ninebark.

How Many Darkstar Ninebark Do I Need?
For an informal hedge or privacy run, space Darkstar about 5 feet apart — at 4–6 feet of mature spread, plants merge into a dense burgundy wall:
| Run Length | Plants Needed (5 ft spacing) |
|---|---|
| 10 ft | 2–3 |
| 20 ft | 4 |
| 30 ft | 6 |
| 40 ft | 8 |
As a specimen, give a single plant a 6-foot circle; for a bold border anchor, plant a group of 3 spaced 5 feet apart.
Darkstar Ninebark Season-by-Season in Minnesota
- Spring: Deep burgundy-black leaves unfurl, followed in late spring by button-like clusters of white-to-pink flowers buzzing with native bees.
- Summer: Foliage holds its near-black color through the heat (darkest in full sun) while red seed heads replace the spent blooms.
- Fall: Seed heads persist and the dark leaves deepen before dropping to reveal the branch structure.
- Winter: Papery, exfoliating bark peels in cinnamon layers — the "nine barks" — giving real texture against snow.

Is Darkstar Ninebark Right for Your Yard?
A fit for sunny borders, foundations, and tough sites in nearly any soil — clay included — where you want native value, deer resistance, and bold foliage contrast with almost no care. Not a fit for deep shade: the burgundy foliage fades toward green and the habit gets leggy without at least half a day of sun.
