It is sometimes used as an ornamental plant. It is a medium-sized shrub growing to {{cvt|11|m}} tall.[2] Its growth rate is medium to fast.{{citation needed|date=July 2018}} The leaves are opposite and divided into three leaflets, each leaflet {{cvt|4.5-13|cm|0}} long[3] and {{cvt|5|cm|0}} broad, with a serrated margin.[2] The leaves are bright green in the spring, turning dark green in the summer. S. trifolia produces pendant white flowers in spring, which mature into bladder-like, teardrop-shaped fruits that contain several large black seeds.[2] Some sources consider these "nuts" to be edible.
