More information
Although sometimes listed as a Briar hybrid, Goldbusch aligns more with a vigorous floribunda in growth and flowering habit than with its wild progenitors. In Germany it is termed a park rose—a tall, freely flowering shrub requiring no special care. Buds are coral pink; blooms open peachy yellow, later fading to cream, after which the flowers deepen and take on a pink tint. When open, the blooms reveal red-brown stamens encircled by small inner petals. Flowers are produced in large clusters of 5–15 blooms, followed by large fruits. The foliage is bright green and susceptible to black spotting. Height varies with climate: in hot countries it reaches 2.5 m or even 4 m, while in cold climates it does not exceed 1.25 m.
