Your article is outstanding! Very informative and inspirational. Hopefully it will encourage more gardeners to try these wonderful plants.
While almost all flowers are beautiful, I like the fullness of the double flowered clematis. I have made an observation regarding another plus of the doubles: the flowers seem to hold up and last much longer -- in my limited experience. I have several unnamed singles and all are already bloomed out. My only double is Vanso Blue Light. It started blooming in early May and is still going strong -- even though planted much later than my others. I also noted that individual flowers last for weeks at a time, much longer than the singles -- definitely a bonus! Am curios if this is just the case with my specific cultivars, or if it applies generally to double vs single flowers?
This cluster of flowers appears semi double upon opening ... But fill out over time
