Summer Wine Ninebark
A Tough, Native-Derived Shrub With Wine-Dark Foliage and Pink Flowers
Summer Wine Ninebark (Physocarpus opulifolius 'Seward') is a refined, compact selection of our rugged native ninebark, with deep wine-purple, fine-textured foliage and clusters of pinkish-white button flowers in early summer. It's about as tough and cold-hardy as a shrub gets — zone 3, adaptable to clay, sun-loving, and practically care-free. Whether you want a dark-foliage anchor in a Maple Grove border, a hardy color contrast in an Edina bed, or a low-maintenance shrub for a tough Woodbury spot, Summer Wine delivers season-long structure and color.

Summer Wine Ninebark Uses in Minnesota Landscapes
Dark-Foliage Anchor
The deep wine-purple, fine-textured leaves make Summer Wine a season-long color anchor in a mixed border, contrasting beautifully with chartreuse, silver, or gold foliage and bright flowers.
Tough, Low-Maintenance Shrub
As a native-derived shrub, it shrugs off clay, drought, heat, cold, and a wide pH range — a dependable choice for hard sites where you want color without fuss. Great for naturalized and pollinator-friendly plantings.
Informal Hedge or Screen
At 5–6 feet, it makes a handsome informal hedge or screen with dark foliage and early-summer bloom. Space plants about 4–5 feet apart.
Best Time to Plant Summer Wine Ninebark in Minnesota
Plant in spring (late April–May, after the ground thaws) for a full season of root establishment, or in early fall (late August–early October) while the soil is still warm. Get it in the ground at least six weeks before the ground freezes. Avoid mid-summer heat and never plant after mid-October or before spring thaw.
How to Plant Summer Wine Ninebark
- Choose a full-sun spot for the richest foliage color.
- Dig a hole twice the width of the root ball and just as deep, so the crown sits at or slightly above grade.
- Loosen heavy clay and mix in 20–30% compost; ninebark isn't fussy but appreciates decent drainage.
- Set the plant, backfill, firm gently, and water in thoroughly.
- Space plants about 4–5 feet apart for a hedge or grouping.
- Mulch 2–3 inches with shredded bark, kept off the stems.
Watering Summer Wine Ninebark in Minnesota
First Year Watering Schedule
Weeks 1–2: water deeply every 2–3 days. Month 1–2: about twice a week. Month 3–6: roughly weekly during active growth, easing off when rainfall is adequate. Stop watering 2–3 weeks before the ground freezes — usually late October.
After Year One
An established Summer Wine is quite drought-tolerant, needing supplemental water mainly during extended dry spells. It's one of the lowest-maintenance shrubs you can plant.
Will Summer Wine Ninebark survive a Minnesota winter? Yes — easily. It's rated to USDA zone 3 and is one of the toughest, most cold-hardy landscape shrubs available, fully at home anywhere in the Twin Cities.
Is it native to Minnesota? Yes — ninebark (Physocarpus opulifolius) is a Minnesota native. 'Seward' (Summer Wine) is a refined, more compact selection bred for dark foliage and a tidy habit, so it brings native toughness with ornamental polish.
Will the purple foliage last all summer? Yes, especially in full sun. In too much shade the leaves green up, so give it good light for the deepest wine color.
Does it tolerate clay soil? Yes — exceptionally well, along with dry sites and a wide pH range, which is why it's such a dependable problem-solver shrub.
Should I prune it? Optional. Prune right after the early-summer bloom if you want to shape it; it also takes a hard renewal cut in early spring if it gets leggy. Its exfoliating bark adds winter interest, so a light hand keeps that on display.

How Many Summer Wine Ninebark Do I Need?
Summer Wine matures around 5–6 feet wide, so space plants about 5 feet apart for an informal hedge or screen.
| Hedge Run | Plants Needed (5 ft spacing) |
| 10 ft | 2 |
| 20 ft | 4 |
| 30 ft | 6 |
| 40 ft | 8 |
As a specimen or color anchor, plant singly or in groups of 3 spaced about 5 feet apart.

Is Summer Wine Ninebark Right for Your Yard?
Summer Wine thrives in full sun and average to well-drained soil, shrugging off Minnesota clay, heat, drought, and cold once established — ideal for a tough, sunny border or low-care informal screen where you want season-long dark foliage. It's not the best fit for deep shade, where the purple leaves green out, or for high-deer-pressure yards without some protection, since deer browse it only moderately.
