More information
Small, vivid crimson blooms form in large clusters. The foliage is dark green, matte. Reaches 4.5 m in height and 3.5 m in width; the shoots are flexible. Suitable for planting against cold walls and can be trained into trees. Tolerates poor soils and partial shade.
This historic hybrid can be grown as a climbing rose, as a groundcover, or in a weeping bush form. Also used for low hedges. When trained on a support, the light green shoots readily reach 4 metres in height. Full inflorescences hang from the lateral shoots. It blooms profusely and for an extended period with double, bright pink, unscented flowers. Spent blooms dry on the plant and require removal. Excelsa flowers once in early summer, and its fresh, shiny light green foliage persists until autumn.
Buds are rounded. Flowers are bright red, long-lasting, small (3–3.5 cm), densely ruffled (70–90 petals), faintly fragrant, in dense inflorescences of up to 60. Leaves are dark green, shiny. Spines are frequent. Shrubs are very vigorous (up to 4 m), with thin, trailing shoots. Flowering is very abundant, lasting 30–35 days. Winter-hardy. Slightly susceptible to powdery mildew. Used in bush culture and vertical gardening. American Society of Rose Growers, Gertrude M. Hubbard gold medal, 1914 .
