the beauty of neps, like sarracenia, is that they can cross and cross and cross and cross! there is no limit to the possibilities! only a few clones of neps are sterile. like the Deroose ventrata, miranda and a few others. but in general they arent sterile.
but from your context i think you are trying to ask if they are self fertile. no. because they are only one gender. PK is doing some kinda work with gender switching. dunno how that is going though.
