VFTs do produce flowers in the spring. There is much debate about whether to cut them off or not. Some feel allowing it to flower weakens the plant. Others let them bloom. The flowers are not spectacular but you could get seed if you want. I always cut mine off.
You can tell a flower stalk as it usually comes up straight and the the top has a little "clenched" looking ball, instead of the kinda elongated, flat end you see on emerging leaves.
Hope that helps. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]
