Clematis blossoms have long stems, and I had managed to avoid killing the plant itself. I found the main vine, which fad several buds on it ready to blossom. Hoping to make it up to the plant, I dug up an old trellis on which I had once tried to train my hummingbird vine. (Ha, ha. Train a hummingbird vine. From its Wikipedia entry: "It grows well on arbors, fences, telephone poles, and trees, although it may dismember them in the process. Ruthless pruning is recommended." Starting about three years after I planted it, I have spent decades trying to kill or at least control the hummingbird vine before it dismembers the house.) I wove the clematis through it, careful to not knock off any buds in the process. And then I waited.
I waited the better part of the week. The buds didn't begin to blossom until Friday, June 1. These pictures were taken the next day.
Additional buds have opened since these photos were taken, and several more are waiting to open.
This flower looks like velvet in the high contrast monochrome images, and the sunlight is much more distinct.
We'll see how big the clematis gets this year, and how well it comes back in coming years.
