Rosa Frau Dagmar Hartopp, also known as ‘Fru Dagmar Hastrup’ and holder of the prestigious RHS Award of Garden Merit, is a hybrid tea rose cultivar that belongs to the family of Rosaceae. It was first introduced in 1914 by the German rose breeder Peter Lambert, and is named after his daughter-in-law Dagmar Hastrup.

This is a hardy, disease-resistant shrub that grows to a height of 1 metre and spreads up to 1.5 metres wide. It has a compact, bushy growth habit and produces a profusion of soft pink, cup-shaped flowers that bloom in late Spring or early Summer, with some scattered blooming throughout the season.   The foliage is a medium green colour with a glossy finish, and is composed of oval-shaped leaves with serrated edges and is arranged in an alternating pattern along the stem.

One of the key features of this variety is its exceptional hardiness. It can withstand harsh winter conditions and is able to grow in a variety of soil types, including alkaline and clay soils. This makes it a popular choice for gardeners looking for a low-maintenance rose that can thrive in challenging conditions.

Another advantage is its versatility. It can be grown as a shrub or trained as a climber against a wall or trellis. It is also well-suited for use in mixed borders, cottage gardens, or as a focal point in a formal garden setting.

Overall, this is a beautiful and dependable addition to any garden. Its delicate pink blooms, glossy foliage, and hardy nature make it a favourite among gardeners and rose enthusiasts alike.

How to care for your Rosa Frau Dagmar Hartopp

  • Planting: Choose a sunny location with well-draining soil. Plant the rose in a hole that is twice the diameter of the root ball and at the same depth. Water thoroughly after planting.
  • Watering: Water the plant deeply once a week, especially during hot, dry weather. Avoid getting water on the leaves, as this can encourage fungal growth.
  • Fertilising: Apply a balanced, slow-release fertiliser in early Spring before new growth appears. Repeat this process in late Spring or early Summer to encourage strong blooming. Do not fertilise the plant in late Summer or Autumn, as this can interfere with dormancy.
  • Pruning: Prune the plant in late Winter or early Spring to remove dead or diseased wood, as well as any crossed or crowded branches. Cut back the remaining branches by about one-third to encourage new growth and maintain the plant’s shape.
  • Mulching: Apply a layer of organic mulch, such as shredded bark or compost, around the base of the plant to help retain moisture and suppress weed growth.

By following these care guidelines, you can help your Rosa Frau Dagmar Hartopp grow healthy and produce beautiful blooms year after year.
