The pink blooms of Frau Dagmar Hastrup open on a dense, rounded shrub in the first flush of the season, and the big red hips that follow stay on the branches into fall. Frau Dagmar Hastrup is a rose worth knowing: how large it grows, where it thrives, how to prune it and what it will give your yard year after year.
What Is the Frau Dagmar Hastrup Rose?
Frau Dagmar Hastrup is a hybrid rugosa shrub rose, sometimes listed as Frau Dagmar Hartopp. It forms a dense, compact plant to 4′ tall. Its height ranges from 2 ft. 0 in. to 5 ft. 0 in. Its width ranges from 2 ft. 0 in. to 4 ft. 0 in.
The flowers are single and shell pink, with 4-7 petals and a strong fragrance. Each bloom measures 2-3 inches across, and the plant repeats its bloom through the growing season and into fall.
What sets it apart from many roses is the show after the petals drop. Large red hips appear early and persist, and the leaves turn a showy bronze in the fall.

How to Care for the Frau Dagmar Hastrup Rose Through the Year
Spring Wake-Up
New growth starts from the base and the older canes. Give the shrub full sun and moist, well-drained loam or sandy loam, and mulch lightly if the soil dries fast.
Late Winter Pruning
Prune by the renewal method in the late winter, as needed. Cut one-third of the oldest canes to the soil line, which opens up the shrub and makes room for new canes that carry the flowers.
Bloom Season
The large pink flowers arrive and keep returning through the growing season. Their scent is strong, so plant it near a path or a seat where you will notice it.
Summer
Once established, the shrub is drought tolerant, so water young plants regularly and let older ones go longer between drinks. Do not deadhead, because the hips form from the spent flowers and they are half the show.
Fall
Leaves turn bronze and the red hips ripen against them. Leave the hips alone and let them carry the color.
Winter
Check the winter protection advice for your own state before cold weather arrives. It is deer and salt tolerant.
Frau Dagmar Hastrup Rose Diseases and Weak Points

It is also salt and deer tolerant, and drought tolerant once established.
| Threat | How Frau Dagmar Hastrup handles it |
|---|---|
| Black spot | Resistant |
| Powdery mildew | Resistant |
| Cercospora leaf spot | Resistant |
| Rust | Very resistant |

Is the Frau Dagmar Hastrup Rose Right for Your Yard?
It suits a sunny spot where a shrub of up to 5 feet tall can spread to as much as 4 feet wide. It asks for little care, but it wants room, and it is a poor fit for deep shade or soggy ground.
- Choose it for a hedge, a border or a coastal yard, where the scent, the hips and the bronze fall leaves give a long season of interest.
- Skip it if you want fully double blooms or plan to deadhead for neatness, since the single flowers and the hips are the point.
