These are big varieties suitable for naturalising in earth bottomed ponds and lakes or large 25-40 litre baskets in big liner ponds. Suitable for 60-100cm depth and will cover 2-3 metres squared in 2 years. Once they have built up a large bulk of rhizome, they can cope with a little greater depth, but of course by then you won’t be able to move them…..

Generally available mid March to September.
