Weed Seed - Syrian bean-caper (Zygophyllum fabago)

Syrian bean-caper is an invasive plant that dominates dry habitats such as rangelands and grasslands. It reduces native biodiversity by forming dense patches that compete with native plants for water and space. Livestock will not eat Syrian bean-caper. Syrian bean-caper is difficult to control with herbicides and is drought tolerant.

Where it's found

Syrian bean-caper has not been found in Canada. It is native to the Mediterranean region and central Asia. It was introduced into Australia and southern Europe, and has been reported in several states in the United States. It is found in dry rangelands, grasslands and disturbed sites, such as roadsides, corrals and gravel pits.

What it looks like
