Prized for their blowsy, glamorous blooms and glossy, deeply cut foliage, peonies are held in deep affection by many gardeners, despite their shortish flowering season and vulnerability to peony wilt in damp weather.

In the autumn, cut off all the foliage and dispose of it to prevent reinfection the following spring.
