The snowball-leaved bladder sparrow ( Physocarpus opulifolius (L.) Maxim. , Syn .: Spiraea opulifolia L. ) is a shrub originally from eastern North America. It is therefore also called Virginian bladder spar and is often found as an ornamental shrub in Europe.
description
It is an upright shrub up to 3 m high. Its leaves are broadly ovate and usually three-lobed.
The white to pink-red flowers are in spherical umbrella clusters with a diameter of up to 5 cm. The petals are up to 4 mm long. The flower has five medium-sized, approximately up to the middle of overgrown carpels .
The fruits are several, reddish, inflated bellows on a flower, which together form a pelvic fruit .
The number of chromosomes is 2n = 18.
General
The wood is native to eastern North America. The bladder spar thrives there in societies of the Salici-Spiraeetea douglasii. It can occasionally be found in our gardens as an ornamental and hedge plant and occasionally as a garden refugee in swamp and floodplain forests.
