'Diana' has deep green foliage and large, pure white flowers that bloom from mid- to late summer. Unlike some other roses of Sharon, its flowers remain open at night. It requires little maintenance and, once established, will tolerate extreme heat, drought, and poor soil. -Judith Ireland, Regional Reports: Northeast, Fine Gardening issue #122
