Rainy Side Notes

When we think about clematis, we most often think of the genus as vines. However, some, such as Clematis intregrifolia 'Hakuree', are herbaceous perennials.

The recurved sepal tips of this long blooming plant makes the flowers look as if they are skirts swirling around during a dance number. The sepals open up with a bluish-white tint during the cooler part of the season and as we warm up later in the summer, they open white.

Here in the Pacific Northwest we can barely grow some of the hardier gardenias; however, we can grow a very healthy gardenia “scent-alike” C. ‘Hakuree’ flower. The fragrance isn’t as powerful as the large gardenias I would pick from the garden at my beach home on the North Shore of Oahu. One blossom filled the entire house with heavenly scent. (After growing them in Hawaii, I can’t bring myself to grow the sometimes barely-hanging-on-to-life gardenia shrubs as the ones I’ve seen growing here.) Nevertheless, nestling your nose down into the swirling sepals of this clematis brings you the same scent of heaven!

This clematis is not a climber, it is an herbaceous perennial that you can let lean on other plants, stake, or let flop on the ground. With its exceptionally long blooming season, this perennial looks elegant growing in hanging baskets. In this image the plant is intermingling with low growing conifers.
