Where can I buy castor bean seeds or plants?
While castor bean seeds my not be available on the seed rack at your local nursery, they do seem to be readily available online. I checked 5 seed companies that provide online, mail-order services and 3 of the 5 offered castor bean seeds. I could not locate a source for plants. One of the online nurseries I tried that offers both plants and seeds only had seeds – as well as a warning that the raw seeds are poisonous.
