Amelanchier spicata

Amelanchier spicata - garden shadblow

Garden shadblow is not known in the wild, but only as a garden plant and escapee in northern Europe. It is thought to be a form or cross of the North American running service berry (Amelanchier stolonifera), and was earlier called Amelanchier botryapium. Garden shadblow has a rather special habit: tall, erect stems in dense thickets. Because it produces only short runners, this method of spreading is not uncontrollable.
