About this plant
This is a grassy looking plant which has spiky leaves and little brown flowers which don't add much. It is a good marginal plant for a pond where it can go into water up to 20cm (8in) deep. The plant has a curious look since the leaves stick out from the central stalk looking like umbrella spokes. It is a useful plant to stabilise banks alongside water. Give this a sodden spot if you don't plant it in water. It reaches around 1m (3ft) height with 40cm (16in) spread.

Autumn · Planting
Prune foliage back
Cut foliage back to the ground in autumn.
Spring
Spring · Outdoors
Feed with aquatic plant food
As the plant is grown in water, feed with an aquatic feed as directed on the packet. Do not exceed the amounts given as this can affect the water.
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water frequently to keep the soil moist
The plant thrives in moist or boggy soil, doesn't tolerate dryness and should be watered frequently, not only after a period of drought, but if the soil begins to dry out spring to autumn. Check plants in pots more frequently, especially in hot weather.
