Each year, this is the third, my clematis Blue Light manages to surpass my expectations. I have read that clematis aren't happy with cold wet springtime weather. After a mild winter, this spring tried to balance things out a bit with many cool and windy nights. And though the annual plants I set out, even the ones after Mother's Day this year were not happy campers, my Clematis Blue Light plants have had their best year yet!
They started blooming with the irises and are still going strong even though only a few of the late irises remain in flower.
Have posted 2 photos taken today, 6/4/16. The one showing the ongoing display, the 2nd showing the most double flower we've had to date.

Is a sport of Clematis Mrs. Cholmondeley. Can have single and double flowers at the same time.

This clematis produces quite large sky-blue blossoms. They may appear to be single blossoms when they initially open, but they then continue to open over a long period of time, until the same bloom is nearly a pom-pom. You may also experience double blooms on the first flush of blooms, and then later a second set of blooms that remain single.

This clematis took a bit longer to get established than some, growing slowly and only producing a few blooms the first couple of years. They appreciate some shade at their base (head in the sun, feet in the shade), if you can plant a low clumping plant at the base.

This is a really spectacular clematis, and well worth the patience it takes to reach that first year of really heavy bloom!
