More information
Multiple roses are marketed under the name Apple Blossom, but the cultivar identified as the original was bred by Jason Dawson at the Arnold Arboretum in 1890 and introduced many years later by Luther Burbank. It is a vigorous rambler. From a distance, the mass of fragrant white-to-pink blooms resembles apple blossom. Buds are compact, pink; as the flowers open they fade until nearly white. Petals have wavy margins. The cultivar is reported to be easy to grow, roots readily from cuttings, and is hardy. The foliage is pale green and large. After flowering it can be affected by fungal diseases.
Flowers are semi-marginal, pink with a white center, fading to white. They appear in small clusters, with wavy petals. The flowers persist on the plant for an extended period, causing the clusters to become very dense; in wet weather the petals rot. At the start of bloom, the white flowers are contrasted by pink buds.
