Lily of the valley have been around in cultivation for many centuries. Convallaria majalis 'Rosea' was first noted in around 1576. Although its likely there may only be one variable species (or 3 similar), grown for the wonderfully scented, creamy-white, bell-shaped flowers, there are many cultivated forms, with larger flowers, variegated foliage, yellow foliage, double flowers or pink flowers. The flowers are on separate, arching stems, amongst strap-like leaves. Often followed by red fruits. Very popular as a cut flower.
The sweetly scented flowers of lily-of-the-valley attract pollinating insects especially bees. The seeds and leaves contain toxic chemicals but they are used as food by the larvae of a number of moth species. Steps should be taken to prevent the non-native cultivars escaping the confines of the garden as these could 'genetically pollute' native populations.
