Also known as fire lily, flag lily or kaffir lily, river lily flowers for several weeks in October and November and even later if the weather does not turn nasty. The most commonly grown kind is ‘Mrs Hegarty’, a pale pink form. This is a vigorous variety that makes a low clump with relatively short-stemmed flowers. Other varieties include the well-named ‘November Cheer’ with tall stems and pink flowers and ‘Major’ which is also tall and has bright red flowers. The two larger plants do not colonise as well as the smaller variety, except in good conditions and, being taller, the stems tend to blow over more easily.
