Bladder Senna Overview
Colutea arborescens is a deciduous shrub species in the pea family, Fabaceae. It has a vigorous, bushy habit and grows well in full sun, typically reaching 3m in height and spread. It produces bright yellow, pea-like flowers measuring approximately 2cm in diameter. These lead onto bladder-shaped fruits measuring between 2-8cm long, which dry with age to form a papery structure containing lots of seeds. Foliage is pale green and divided into a pinnate arrangement; oval leaves are produced in opposite pairs either side of stems, similar to a feather. They are slightly hairy and measure around 3cm in length. This plant is native to Europe and North America but is commonly found in other locations due to its popularity as an ornamental plant. It is also used in landscaping as an erosion control measure, and in many locations it has escaped from cultivation and grows wild.
