We bought this as a very small plant three or four years ago. It grew to about a metre tall this year and flowered for the first time. It's planted at the side of the pond and the idea was that it would grow over the pond like a fishing rod but of course it's growing the opposite way. It's very pretty though.
Never heard or seen this plant - so interesting and a lovely flower ! Plant are all the same when deciding where and when to flower - Shame it does not hang over your pond !
