Any notable cultural or growth differences between Carex plantaginea (seersucker sedge) and C. platyphylla (silver sedge)? Maybe one works better in sun the other? One has higher water requirements? Etc. Curious if one has a better niche than other...

I already have the seersucker sedge. Pictures of them look very similar to each other. Just seeing if it would be worth it getting a silver sedge.
