Rose breeder David Austin is famous for bringing together the shapes and scents of old-fashioned roses with the repeat bloom, hardiness, and disease resistance of modern roses. Like all roses, the more sun you give them, the more flowers you'll get in return. Remember that without full sun and good air circulation, even the most disease-resistant roses may need help fighting fungal diseases. Also, repeat-blooming  roses are heavy feeders, so for best performance fertilize in spring and again in mid-summer.
