Clematis, especially Ruppel does very well in Vermont, but it must be trimmed back carefully each fall and we fertilize on an every two week schedule beginning in Mid May. The pic I just posted, when it shows up, is going to look "fake", but it really IS Dr. Ruppel on our front porch!

I have had a vine for 2 full years now, against a trellis at the gate to my backyard. It does not do a good job of using the trellis, tends to grow away from the support instead of up, and will only grow to 3 feet for me. However, it blooms reliably over several months, and the flowers are large and stunning. It is a show-stopper despite its lack of height and is a wonderful greeting for guests to our yard.
I have The President clematis and this one planted together. The President has about 10 blooms while Dr. Ruppel has only one. Not a heavy bloomer at all for me.

Lovely blooms. Shorter than some clematis that I have. It blooms from the ground up and also offers some rebloom later in the summer.
