Common name: Purple loosestrife. Créachtach.
Perennial. Beautiful tall flower spikes, with a multitude of purple flowers, up to 1.5m tall. Once established will give years of flowering.
Not only astounding to look at but the many flowers provide for insects in mid to late summer.
This will be happiest beside your wild life pond, stream or wetland area. It can cope with drier situations as well. Prefers full sun. Feed well for best results.
Sow late autumn or preferably early spring into a seed tray, prick out when large enough to handle and plant out when big enough.
Not so much a wound herb as the Irish name suggests but used to cure diarrhoea and dysentry in past times.
