Flowers perfect, not fragrant, 6-13 cm across; white, pink, rose and red, with many different forms, e.g., single, semidouble, formal double, peony, etc. They may bloom from early winter to spring.
- Sun to part shade. Prefers moist, acid, organic, well-drained soil. Mulch roots since they are not particularly deep.

- Many clones, well over 2,000, have resulted from the breeding and selection of both professionals and armatures. Some selections are registered whereas others are not and there is much confusion in equating some names with a particular plant. Dirr (1998) states that the situation is confused "to the point of hopelessness".
