Description:
Syrian bean-caper is a succulent perennial, forming a compact multi-branched
shrub - decumbent (spreading low to the ground) to ascending (upright).
Mature shrubs may grow to three feet tall and spread three feet
in diameter. The leaf arrangement is opposite. The compound leaves
consist of a pair of leaflets that are thick, leathery, fleshy,
and glabrous (smooth and hairless). The flowers are perfect. Solitary
flowers are stalked, and found in the upper leaf axils. The five
sepals are green. The five petals are white to cream with salmon-colored
markings. There are 10 orange stamens extending past the petals
(Roche’ 1991). The fruit is a four to five celled capsule
with one seed in each cell. The seeds are brown and rough with a
slight kidney bean shape. The perennial tap root can be up to several
inches in diameter with multiple branches from the crown.
- Mechanical:
Small infestations of Syrian bean-caper can be hand pulled, making

- Herbicide:
The surface area of the leaves of Syrian bean-caper are smooth
and waxy, making herbicide control difficult. Refer to the annually
updated Pacific Northwest Weed Control Handbook.Refer to the State
