[Yes.](http://www.accesskent.com/government/departments/health_qa_ricin.htm)

> Ricin is a potent toxin derived from beans of the castor plant (Ricinus communis). The naturally occurring toxin is fairly easily removed from bean pulp remaining after castor oil extraction. Although ricin itself is not volatile, it may be formulated as a powder or an aerosol for intentional airborne dispersal. It is difficult to detect in human tissues or the environment. It can persist in the soil or environment for up to three day.

The Castor bean plant is commonly grown as an ornamental in the US. Its height, and large leaves [(pics)](http://images.google.com/images?q=castor+bean&hl=en&lr=&ie=UTF-8&safe=off&as_qdr=all&sa=N&tab=wi) make it a natural choice for garden backgrounds. The plant is winter hardy in the southwest, and is a common weed species in AZ, and So. Cal. It also makes frequent appearances in movies as a jungle-plant stand in.  
The ricin containing seeds of the plant are also the source of commercially valuable castor bean oil. [More](http://chiron.valdosta.edu/rgoddard/biol4900/corbett/corbett2.htm) on castor beans, castor bean oil, and ricin.

NBC’s Jim Miklaszewski gleefully reported as fact what he was told by ‘sources’:

> The sources said U.S. troops also discovered about 300 sacks of castor beans, which are used to make the deadly biological agent ricin, hidden in a warehouse in the town of al-Aziziyah, 50 miles southeast of Baghdad, the capital. The castor beans were inaccurately labeled as fertilizer.

Thanks Jim. Good, um…journalism.
