Well you could water it and hope some foliage held onto some moisture on the inner sides of the flowers, and it could potentially survive? Idk.. too tough to tell the condition from a picture, I'd have to feel it. Either way its gonna be stressed as a muhh fukkah. If you've got other healthy plants and such... I'd say just chop it down and mark that one as a loss, then focus your energy and time on your healthy plants.

Why wasn't it watered for 10 days anyways? Vacation or something? Its too bad seeing that happen..
