Well I just googled it and it seems some varities sometimes do rebloom. Hope they do this year! :)

It's July 25 and my clematis is reblooming just like I remembered! It's just a few flowers on the newest growth. Yay!

Boy, some people have all the luck.

My first clematis two years ago came up after I'd given up and covered the spot with a cedar planter. It decided to grow up behind the planter, but I pulled a "weed" and realized as soon as it was out of the ground that it probably was my clematis ! My Nelly Moser ( from two years ago also)didn't come up this year. I was really looking forward to seeing what blooms I would get in it's third year.....

Enjoy your rebloomer =:)

LOL, I don't have ALL the luck. I know there are clematises in heaven because I have sent several there myself. I just happened to hit on this nice alpina that loves my yard and even makes babies for me. :0)

It interests me that yours came up under a planter. Many people swear if you cover their roots with a big rock they love it. They do like their roots cool anyway. I plant mine with small flagstones all around them, and other perennials to shade their roots.

The clematis that probably came up from under the planter, may have had part of it's roots past the edge of the planter. It's a fairly large cedar box, so it couldn't be moved as it was already full and heavy.

My Nelly Moser was planted against a fence with some bricks piled around it to keep the roots shaded. They weren't right on top though. How close do you plant the other perennials? I plunked a bit of compost on top this spring before any growth came up ( well, growth I thought would come up). Do you suppose I smothered it? If it was going to come up, wouldn't it have just grown up through the compost?

I looked up your Alpina on the Fine Gardening website. Very pretty. I clearly have a lot to learn about clematis as I thought they all grew in full sun. Fine Gardening says it likes partial to full shade. Really?

I have columbines, gayfeather (Liatris), and some Rudbeckias about 18" in front of the clematis, which is growing against my shed wall. The shed is on a concrete slab so the clematis roots are probably under that too.

Clematis definitely like their roots cool. I have read that they like their "feet in the shade and their heads in the sun", as they are naturally a forest vine and will grow on the shady forest floor and scramble up trees to find the sun.

I haven't has as much luck with the larger-flowered clematises so you might not have done anything wrong. From what I've seen around here Jackmanii is pretty reliable and any of the Alpina group. I had a Nelly Moser and a Viticella (name forgotten) at my old house but I moved before I could see how they fared. I would like to try a Viticella again.
