The Great reedmace is a strong growing plant, resistant to waterfowl. It is a good filtration plant, removing impurities from the pond water. The seed heads are sturdy brown pokers, often used in flower arrangements or dried for winter decorations. Reedmace is often wrongly referred to as ‘Bulrush’. Tall, emergent plants provide habitat for pond insects, especially emerging dragonflies. It can be planted up to 60cm deep, useful for deeper water areas where some other marginals would not thrive. Plant in a medium or large container using aquatic soil and covering with pea gravel. Trim off old foliage in spring and remove unwanted side shoots.
