Both flowers and foliage are small and elegant, on a big shrub-sized plant. The stems are slender and wiry but strong and self-supporting, and support the leaves and flowers almost invisibly. The whole plant has a see-through quality, and I suspect it would look good as a scrim plant toward the front of a deep mixed border.
The flowers are self-cleaning, and the foliage is clean and unblemished. As the name suggests, the deeply cleft leaves do look a bit like cannabis.
I'm eager to try using this in a garden.
