About Roseraie de l'Haÿ

As one of the species & wild roses, Roseraie de l'Haÿ carries the traits gardeners look for in the group — simple five-petaled single flowers, usually followed by ornamental hips. As one of the wild ancestors of the garden rose, it trades repeat bloom for toughness, wildlife value, and an easy, natural beauty.

Characteristics and form

Roseraie de l'Haÿ makes arching, often large and informal plant, typically around a wide range, roughly 3 to 10 feet tall and wide. The blooms are simple five-petaled single flowers, usually followed by ornamental hips, small to medium in size, set against often distinctive — sometimes ferny or grey-green foliage. Knowing a rose's habit and mature size is the key to placing it well: give Roseraie de l'Haÿ room to reach its full spread without crowding its neighbors, which also keeps air moving through the plant and disease at bay.

How to grow Roseraie de l'Haÿ

Plant Roseraie de l'Haÿ where it will get at least six hours of direct sun a day in fertile, well-drained soil with good air movement around it. In cold climates, set the graft union — the swollen knob where the variety joins the rootstock — at or just below the soil line; in mild climates, keep it at soil level. Once planted, water deeply and less often to encourage deep, drought-resistant roots.

  • Light: Full sun, six hours or more; morning sun is best because it dries dew early and limits disease.
  • Soil: Rich and well-drained, slightly acidic at about pH 6.0–6.5. Improve heavy or sandy soil with plenty of compost before planting.
  • Water: Deep, infrequent soakings at the base rather than frequent light sprinkling; more in heat, sandy soil, or containers.
  • Feeding: A balanced rose fertilizer in early spring, repeated after the first flush to fuel the next.
  • Pruning: Prune it in late winter to an open, outward-facing framework, then deadhead through the season.
Bloom habit: Repeat (recurrent). Roseraie de l'Haÿ blooms in repeated flushes from late spring until the first frost. Deadhead spent flowers to bring on the next wave.
