I bought a ruby glow from logees two months ago. It is in a pot in a sunny window. It was growing nice but getting too tall for the window and the other plants near by. So I cut the top off it. It still looks healthy but since I pruned it, it hasn't grown an inch. I was expecting to see two shoots where I pruned it. I didn't hurt it did I? This is my first passion vine. I was hopeing to get it nice and strong this winter, then put it out for the summer. filix
