Dagmar Hastrup

Rosa rugosa 'Dagmar Hastrup'

Growth Characteristics

Rosa rugosa 'Dagmar Hastrup' is a shrub-type rose that grows primarily along coastlines, reaching a height of approximately 60–90 cm. Its leaves are dark green and turn yellow in the autumn, providing a visual spectacle. Pink flowers bloom from summer to autumn in single or small clusters, emitting a strong fragrance. It also bears bright red berries in the fall.

Propagation Methods

Rosa rugosa can be propagated primarily by seeds or cuttings. For seed propagation, seeds are extracted from mature berries in the autumn and planted immediately, or stored in the refrigerator and sown in early spring. For cuttings, new branches are cut and propagated in the summer.

Cultivation Methods

Generally, Rosa rugosa thrives in well-drained, sunny locations. Due to its salt tolerance, it grows well even along coastlines, so it can grow without issues in standard garden soil. It tolerates dry conditions relatively well and requires no special winter protection. Uses in the Garden

Rosa rugosa is highly popular as an ornamental plant, hedge, and screening plant. In particular, it is widely used in coastal landscaping because it can withstand strong sea breezes. Additionally, its flowers and fruits provide diverse visual appeal to the garden.

Important Pests and Diseases and Control Methods

Rosa rugosa is relatively resistant to pests and diseases, but it may occasionally suffer from aphids, powdery mildew, and black spot disease. Aphids can be removed by washing with soapy water or using general insecticides. For powdery mildew and black spot disease, diseased leaves should be removed immediately, and appropriate fungicides can be used as a preventive measure. Above all, it is important to maintain a healthy growing environment through proper aeration and watering.
