betulia bargain !!

whilst at our local Tesco store they were selling off all there left over stock from the bank holiday flower promotion that they had over the weekend and we got this potted betulia for one pound 25p down from a tenner,compost was dry as dust so we gave it bf&b and a good feed of liquid growmore and it seems to be going great guns ! . . . . my question is cos neither of us are familiar with this plant is it part of the geranium family and if so are we able to take cuttings from it at this time of year and if the answer is yes how do we do it  as its all new to us,also on closer inspection it seems to be 4 separate plants potted up together. . .does that make sense,sorry to be so dim but really want to be successful with something this year   

cheers jay & jane
