It may be too late to try to root one. But no harm in trying.
I cut a shoot, cut a couple lower leaves off, cut the flowers if present, put in a pot with good,saturated potting soil, put a plastic bag over the entire plant and close it around the pot. Make sure you put a few holes in the top of the bag. And make sure it doesn't touch the leaves. Leave for a couple of weeks protected from direct sunlight. Pull back off after a couple of weeks. Sometimes they take, sometimes they don't.
