  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Aug 3, 2018 10:58 AM concerning plant:
    The Black Jetbead is native to Japan and central China. It is a nice, pretty, clean shrub, though not flashy. It has bright green doubly toothed leaves to about 4 inches x 2 inches that resemble birch or elm leaves that only get a poor yellowish-green fall colour. Young twigs are green, shiny, and hairless that turn brown to become gray-streaked and reddish-brown. The white flowers are about 2 inches wide with 4 petals, which is unusual for a member of the Rose Family. The shiny black berries are in clusters of 3 or 4 and are present from autumn into spring. Easy to transplant with fibrous roots. It is not a common plant in the Midwest to the Atlantic Coast in the US. Some large, diverse, conventional nurseries offer some, and it is landscape architects or designers that know of this species and might occasionally use it. I saw a very few in the Chicago , IL, area and I've seen it in two locations in southeast PA. One Pennsylvanian location, in West Chester, was near a 18th century house of poor condition that had a number of less known ornamental woody plants around its large property that in 2018 has been totally erased and is being developed into a site for several large houses. Some escaped shrubs in the nearby open woods were also erased along with the woods. The other PA location near Media had a number of jetbeads planted in the back landscape by a lady who was a horticultural enthusiast. I see it as a nice plant but I am concerned about any more east Asian plants escaping cultivation into the woodland edges, though I don't think this species was really invasive.
