Just plant the motherplant where you want it and leave the plantlets on the flower stalk till they have at least a couple of good and, say, at least 3'' long roots (the more the better). The plantlets will reorient themselves slowly towards the light and surface but you might still have to prune them a bit when you take them off the stalk. There might actually be more than one plantlet per node (whorl) so that might add to the plantlets growing all over, too.
When the babies have enough roots you can either just twist them off the stalk and plant them, or you can cut the stalk and then plant the babies. In the latter case, you'll end up having a small bit of stalk amongst the babies' roots decomposing in the substrate - but a small amount is not that harmful.
