Sneezewort is a perennial which spreads by rhizome. It is quite common in damp, shady meadows and waysides, although it is also tolerant of sunny conditions. Flower arrangers use the long lasting white flowers and the more regularly it is cut, the better it flowers. It supposedly causes sneezing, but also yields an oil used as an insect repellent.
Sow preferably in autumn, but will germinate any time.
Seed from Shropshire
