Vern,
Looking good so far. I can see where you had your faceplate attached.
To answer your question, a #5 blade should work for this. Or even a #7. Practice on a scrap to see what you are comfortable with.
Go very gently on the turning. You could snap off the stem or one of the outer pieces of the leave if your gouge should catch.
Please show us the bowl when you finish it.
