Water hawthorn appears to self seed - it is all over our pond in stones,
pots, the mud at the bottom, everywhere.
We have to weed the pond to keep it under control.
Fortunately it seems to flower early (February sometimes) and to be mainly
over when the water lillies get into gear, so they don't compete too much.

I am sure your water hawthorn will adapt though. I failed to follow
Kay's
cunning advice with mine and just dumped it ruthlessly into deepish
water -
in a couple of days the stems had stretched up to the surface anyway and
this year it has had a lot of spidery little baby hawthorns.

Does it self seed as I have lots of spidery things growing in the pond ?
