Colutea arborescens

This is a genus of Leguminosae, conspicuous by reason of the bladder-like fruits. The species are useful for shrubbery work, as they grow and flower well almost anywhere. The chief species are:

Colutea arborescens, the Bladder Senna, found in the Mediterranean region, and introduced in 1570. The flowers are yellow, and borne during late spring and summer. It grows from 6 to 10 feet high.

Colutea cruenta, from the Orient; is similar to the above, but with brownish blossoms.

Colutea longialata is very like Colutea arborescens, except that the wing petals are longer. It is a native of Asia Minor.
