Rosa Mundi
Ancient striped gallica.
The Rosa Mundi is a pink/white striped old garden rose valued for its generous early-summer display and memorable fragrance. Below you'll find a full profile of Rosa Mundi — its characteristics, how to grow it, where to use it in the garden, and answers to the questions gardeners ask most.
About Rosa Mundi
Rosa Mundi belongs to the old garden & heirloom roses, a class defined by full, many-petaled blooms, often quartered or cupped. Prized for depth of fragrance and full, romantic form, the old garden roses carry a character that many modern roses cannot match.
In flower, Rosa Mundi is pink/white striped and gives one memorable, concentrated display, carrying a strong, carrying fragrance. It is hardy across USDA zones 4-8, so it suits a wide range of gardens with the right seasonal care.
Characteristics and form
Rosa Mundi makes an arching, informal shrub in most classes, typically around 3 to 6 feet tall and 3 to 5 feet wide. The blooms are full, many-petaled blooms, often quartered or cupped, medium to large in size, set against often matte green foliage. Knowing a rose's habit and mature size is the key to placing it well: give Rosa Mundi 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 Rosa Mundi
Plant Rosa Mundi 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 to support its single flush.
- Pruning: Prune it after the main flush and only lightly, since it flowers on wood formed the previous year.
Bloom habit: Once (early summer). Rosa Mundi blooms once, in a single generous flush in early summer. Leave the last flowers to form hips for autumn and winter interest.
Where to use Rosa Mundi in the garden
Rosa Mundi suits heritage and cottage borders, fragrant gardens, and specimen shrubs. It is at home in a romantic, informal planting with other old roses and cottage perennials. For more ideas, see our guide to companion plants for roses.
Common problems and care
