Bladder Senna (Colutea Arborescens) 25 seeds (#104)
Colutea arborescens is a species of leguminous shrub known by the common name bladder senna. It is native to Europe and North Africa, but it is known on other continents where it is grown as an ornamental and used in landscaping for erosion control. It is also known in the wild as an occasionally weedy escapee from cultivation. The shrub takes a rounded form and has many branches covered in deciduous leaves. The leaves are made up of many pairs of slightly hairy oval-shaped leaflets, each up to about 3 centimeters long. The inflorescence is a raceme of generally pea-like yellow flowers about 3 centimeters long. The fruit is an inflated bladdery pod which dries to a papery texture. It is 2 to 3 centimeters long and contains many seeds. (info source: wikipedia.org)
