uk plant ID please

[Kezzab]

hi, I'm trying to identify the plant pictured below. The flower spike is in the centre of the pic,

the leaves are the copper coloured ones floating flat on the surface.

I thought it was Luronuim Natans but the flower seems wrong.

It grows wild in Cumbria, in still and flowing water.

Looking at the flower it looks like a Potamogeton sp. Looking at the floating leaf with the redish color, it likely is the Potamogeton natans.
You find it all over europe.. Next to the P. Crispus

Aha! Thank you, that looks about right. Good to know.

Both are pretty and very easy plants btw, the natans has 2 different growforms, submersed it develops slender grass like leaves and the floaters and flowers ofcourse.. But as the name says it's a weed, if temps are high and rich in ferts it can easily become a pest. But the tropical Potamogeton sp. have much more decorative flowers and some are equaly easy if planted in a very rich substrate. Rather pic one that doesn't need dormancy, but most in the trade don't and are cultivars.. Th enon cultivars which do not need dormancy are less easy to grow. I'm growing a P. Robinsonii at the moment, but my substrate isn't perfect for it, so it strugles a bit.. Yet not mature enough to float and flower.. Hoping to get there..

OOps.. Sorry i always mix the names up.. I was mistaken.. It's Aponogeton Robinsonii.. I'm growing in the tank.. The both Potamogetons i have in the garden..
