Sagittaria questions

[Nont]

Hello,

I found this Sagittaria(?) sell online and got few of questions:
1. What species is this?
2. How can I propagate them?
3. Do they have submerged form like S. subulata?

Cheers

Looks like it, thanks for the id!

From the link and information that I find online about this plant. It seems like they have submerged form aswell, makes me wondered why no one have used it in the aquarium.
