The Association of German Perennial Gardeners has the Willow Rich (Lythrum) chosen as perennial of the year 2024. The genus with around 35 species is an insect magnet for bees and butterflies with its large, mostly pink or pink-colored flower candles.
Both species can bloom from June to September and, another advantage, snails avoid the frost-hardy plants. It is better to stay away from perennials with brown, heavily matted or even slimy roots, as this could be a sign of waterlogging.
