If I'm reading this correctly the flower has bloomed and you are left with the flower stem and potential seed pods. I don't know if hanging Geraniums make seeds because I remove mine when the flower is finished but that's what they are. Well like I said --just like regular zonal Geraniums you remove them back to the stem and do the same after the flowers yet to come have bloomed. Sometimes they flower beside tiny off shoots that will get large and make more flowers, so be careful just to remove the flower stem.

Ivy leafed Geraniums will not give you a mass of flowers but it should have a continuous turnover of 3 or 4 flower stems at a time and the ivy shaped leaves are decorative in themselves
