    Although this tree (which was planted as a small mail order purchase) is described as tolerant in zones 5 through 9 (Missouri Botanical Garden site), it has shown extreme hardiness. It has withstood an open position in a rural northern zone 5, and it survived two growing seasons of significant drought without much supplemental watering and then a record-breaking winter that killed plants purported to be hardier. The bloom on the tree this year is spectacular. It makes a perfect addition to a mixed border perennial scheme with its interesting bark, nice glossy leaves, and delicate bracts of white flowers in August, providing true four-season interest.

    My biggest customer in West Chester, PA, a plant enthusiast, had one of this Seven-son Flower shrubs planted in her backyard, though it is surrounded and shaded by some other shrubs and a tree so that it is not an excellent specimen. Otherwise, I've just seen it at some arboretums and botanic gardens. The Arnold Arboretum in Boston, MA, supported the introduction of this species from China in 1980. I find this member of the Honeysuckle Family to be an interesting plant, but not really that lovely. Its white flowers are loved by bumblebees and some other pollinators.
