What plants flower in the Ocean?

Question

Thanks!

Answer 1

Kelp does, but that's the only one i know.

Answer 2

probably none, because of the salt is not a very friendly environment for flowering plants (i'm thinking water-lilies type of flowering plants, not deep-ocean sea weeds...)

Answer 3

Kelp is not a flowering plant.  A flowering plant in the ocean would be something like the following.  Both grow in shallow water near the shore.

Ruppia maritima
