Planting & Care Instructions

Where to Plant

Sunlight: Give this rose full sun, meaning at least 6 hours of direct daylight, to ensure the heaviest bloom and strongest canes. While it tolerates partial shade better than many hybrid tea roses, too much shade will reduce flower production and make the plant leggy.
Soil: This variety is exceptionally tolerant of poor, sandy, or rocky soils and can even handle salt spray, making it perfect for difficult sites. However, it absolutely requires excellent drainage and will struggle in heavy clay that holds standing water.

Watering Requirements

Water deeply and consistently during the first year to help the roots establish, checking the soil moisture weekly. Once established, this Rugosa rose is quite drought-tolerant, though providing water during long dry spells helps maintain lush foliage and supports a stronger rebloom.

Pruning Tips

Prune in late winter or very early spring while the plant is still dormant to remove dead wood and shape the shrub. Because this variety produces large, showy hips (fruit) that add winter interest, avoid deadheading the spent blooms late in the season so those hips can form.

Fertilizer Needs

Feed with a balanced, slow-release rose fertilizer in early spring just as new growth begins to emerge. Avoid applying nitrogen-heavy fertilizers after August, as this encourages soft new growth that will not harden off in time for winter freeze.

Frau Dagmar Hartopp Rose: The Tough-as-Nails Beauty

Picture a rose that offers the intoxicating scent of wild roses but asks for almost nothing in return. With silvery-pink petals fluttering against crinkled, emerald foliage, the Frau Dagmar Hartopp Rose brings a sophisticated, rugged beauty to even the most difficult corners of your landscape. This isn't just a pretty face; it’s a workhorse shrub that thrives where delicate garden roses fear to tread.

Why Gardeners Love This Rugosa

Unlike high-maintenance hybrid teas that demand constant scheduling, this compact rugosa rose thrives on benign neglect. It solves the common dilemma of wanting a flowering boundary without the endless pruning or chemical sprays. You get a dense, low barrier that effectively deters deer and neighborhood pets thanks to its thorny canes, all while perfuming your yard with a rich, clove-like spice. It is widely recognized as one of the most disease-resistant shrub roses available, keeping its foliage clean and green even when humidity spikes.

Planting for Success

You might see this plant listed in catalogs as Rosa rugosa 'Fru Dagmar Hastrup' or 'Frau Dagmar Hastrup'—don't worry, it is the exact same outstanding cultivar. Gardeners in the coldest climates (down to USDA Zone 3) rely on its iron-clad hardiness, but it performs equally well in warmer zones up to Zone 9.

For the most prolific flush of blooms, give this rose full sun. While it tolerates sandy, poor soil better than almost any other shrub, the one thing it cannot handle is standing water. Ensure your planting site drains well, and this rose will reward you for years.

A Four-Season Show

The performance starts in late spring with single, satiny pink blossoms that feature a creamy center and golden stamens. Unlike many shrubs that bloom once and quit, Frau Dagmar Hartopp often repeats its bloom cycle through late summer. As the weather cools, the foliage turns a warm bronze-gold, setting the stage for the grand finale: massive, tomato-red rose hips. These colorful fruits—resembling cherry tomatoes—persist well into winter, feeding hungry birds and adding bright red cheer against gray winter skies.

Where to Use Frau Dagmar Hartopp

Because this is a highly salt tolerant hedge rose, it is a smart choice for coastal gardens facing ocean spray or suburban properties along salted winter roads. Plant a row along a sidewalk, driveway, or front walk; its naturally dwarf habit (staying roughly 3–4 feet tall and wide) means it won't block your windows or view. It is also an excellent candidate for anchoring sandy hillsides where other plants struggle to take root.

Whether you plan to harvest the vitamin-rich hips for jams and teas or simply want to enjoy a hassle-free floral display, this Rugosa is ready to get to work. Add a few to your garden plan today and enjoy the peace of mind that comes with a truly resilient rose.

Frequently Asked Questions

Is Frau Dagmar Hartopp the same as Fru Dagmar Hastrup?

es. You may see this rose listed under several names, including Fru Dagmar Hastrup, Frau Dagmar Hastrup, or Fru Dagmar Hartopp. They are all the same exact cultivar. It is widely considered one of the finest of all Rosa rugosa varieties for its compact habit and clear pink color.

How big does Frau Dagmar Hartopp get?

This is considered a "dwarf" or compact Rugosa rose. It typically grows to a manageable mature height of 3–4 feet with a similar spread. Its dense, bushy habit makes it an excellent choice for a low, informal hedge that won't obscure views or overtake small garden spaces.

Do I need to deadhead this rose?

No! In fact, we recommend you don't deadhead Frau Dagmar Hartopp. While it is a repeat bloomer, removing the spent flowers means you will lose out on the large, tomato-red rose hips that form in late summer and fall. These hips are highly ornamental, edible (great for tea or jelly), and provide essential winter food for birds.

Will this rose grow in sandy soil or coastal areas?

Absolutely. Frau Dagmar Hartopp is exceptionally salt-tolerant, making it perfect for seaside gardens or driveways exposed to winter road salt. It also thrives in sandy, poor soils where more delicate roses would struggle, provided the drainage is good.

Is Frau Dagmar Hartopp deer resistant?

Yes. Like most Rugosa roses, it is known for being deer resistant thanks to its very thorny canes and textured, thick foliage. While no plant is 100% deer-proof if animals are starving, this rose is generally left alone in favor of tastier snacks.
