In the foreground is a bamboo, Hibanobambusa tranquillans 'Shiroshima'. The flower in the background is a variety of herbaceous peony called 'Charm'. The flower form is Japanese pom-pom. These two show stoppers never fail to look great together.
While the larger types of bamboo don't usually do well when combined with smaller plants, the smaller species of bamboo such as this 'Shiroshima' do great and look amazing when combined with other plants of bright, contrasting colors!
