They are [[deciduous]] [[shrub]]s growing to 1-3 m tall. The name comes from the appearance of the [[bark]], which is flaky, peeling away in many layers. The [[leaf|leaves]] are [[maple]]-like, palmately lobed, 3-15 cm long and broad, with an irregularly serrated margin. The [[flower]]s are white with five petals and numerous stamens, produced in [[corymb]]s. The [[fruit]] is a cluster of inflated [[follicle (fruit)|follicles]], which turn dry and brown and then split open to release the seeds. ;Selected species *''[[Physocarpus alternans]]'' ('''Dwarf Ninebark''') *''[[Physocarpus amurensis]]'' ('''Asian Ninebark''') *''[[Physocarpus bracteatus]]'' *''[[Physocarpus capitatus]]'' ('''Pacific Ninebark''') *''[[Physocarpus glabratus]]'' *''[[Physocarpus malvaceus]]'' ('''Mallow Ninebark''') *''[[Physocarpus monogynus]]'' ('''Mountain Ninebark''') *''[[Physocarpus opulifolius]]'' ('''Common Ninebark''') ==External links== *[http://plants.usda.gov/java/profile?symbol=PHYSO USDA Plants Profile: ''Physocarpus''] *[http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?Physocarpus Jepson Flora Project: ''Physocarpus''] *[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=125317 Flora of China: ''Physocarpus''] [[Image:Physocarpus monogynus bark1.jpg|thumb|left|Bark of ''Physocarpus monogynus'']] [[Category:Rosaceae]] [[da:Blærespiræa]] [[es:Physocarpus]] [[pl:Pęcherznica]] [[pt:Physocarpus]]
