Will a pampas grass plume continue to open if cut when its just opening?
I have been give some pampas grass plumes some of which aren't quite open yet. What can I do so they will open fully?

Once they are cut from the plant, they will not open much more than they are now. The only way is to allow them to fully mature on the plant before harvesting.
You could try putting them in a vase of water just ot see if that helps.
