Bog cotton is a species of sedge. It is often found on peat or acidic soils, in open bog, wetland, heath or moorland. It begins to flower in April or May and then develop distinctive white seed-heads that look like tufts of cotton. Bog cotton fibres are brittle and not suitable for textiles but they have been used as a substitute in the production of paper, pillows, candle wicks, and wound-dressings. The plant is edible and has a reputation for being effective in treating digestive problem.
