Do Hostas produce runners like that?  I wish some of mine did!    It would be so much easier to keep ahead of the snails if the hostas spread freely.  If there are hosta species that do, I am very interested in hearing more about them?

Hosta 'Yellow Splash'  produces plenty of runners, certain clones of it in at least 30 cm distance between individual plants.
Miniature Hosta 'Mount Kirishima' produces offsets on 3 cm runners, and I suppose
the plant in the picture is a seedling of it.

Thanks again everyone. It's not a hosta. Mine are now dormant but this one is green. Tell us more about Mount Kirishema

I definitely need to find that sort of Hosta.    Maybe it could keep ahead of the snails after all.

If it is not a Hosta, so it is not a Hosta. You can observe the plant thoroughly, not me.
It is too glossy to be a Plantago, Alisma or Echinodorus.
A relative of Cryptocoryne and Lagenandra perhaps, but which.
If you plant the offsets in an aquarium now, you can check whether it
is a water plant or not.

The resolution of the image is not sufficient. The plant has crenulate margins of leaves if I observe correctly.
Correct me if the margins are different.

Great Moravian where do you live in the Czech Republic?

[Paul T]

Mark,

Well that definitely looks like it takes the 'Calla Palustris' out of the equation.  Wrong leaf venation as far as I can tell.  Hopefully others can come up with what it is.

It resembles Valeriana. But which Valeriana is so glossy. The leaves of Swertia are elliptic. Venation in Alismataceae is different.

The ironical comments above suggested you are certain about the identity of the plant.

It is necessary to add a comment for the historians who might think Mark was absolutely stupid.
I completed my signature after his query for his information.

Absolutely?

Absolutely?

My English is not brilliant. You can substitute an appropriate expression for it.
I can imagine the results of my effort if I compare Czech writings
by foreigners.
