English shrub rose (Rosa 'Graham Thomas')
ROE-sah
Genus:
Rosa
This notable rose has quartered-rosette, double blossoms of rich yellow. It produces arching stems to 5 feet or more, making it an ideal candidate for training up a low structure.
Noteworthy Characteristics:
Most English shrub roses bloom from spring to fall, with large, single to double, mostly fragrant flowers. They make ideal companions in mixed borders, in hedges, or as specimens.
Care:
Grow in fertile, moist, well-drained soil in full sun or partial shade. Provide good air circulation and remove fallen leaves to help prevent disease. Prune lightly or back by up to 1/3, reducing side shoots by 1/2 to 1/3. To renovate, prune one in four or five shoots from the base.
Propagation:
Take softwood cuttings when bloom initiates in spring to summer; take hardwood cuttings in fall.
Problems:
Aphids, leafhoppers, spider mites, scale, caterpillars, sawfly larvae, cane borers, Japanese beetles, rose stem girders, rose midges, rose slugs, rose chafers, leaf-cutting bees, black spot, rust, powdery mildew, crown gall, canker, dieback, downy mildew, viruses.
