Most marginals will just adapt madpenguin - coping easily with up to six inches of water above them. If you put them in at around two or three inches, that will be fine for them and allows for any evaporation during the summer.
I can't do the links here to put you onto one of the many pond threads we've had, but you could look at one of the specialist nurseries online which will give you ideas. Puddleplants or Merebrook for example.
Also - how big is your pond, as that affects the amount of plants you would put directly into it.
