There will always be room in my garden for many Castor Beans.

Zanzibarensis, also recorded as Zanzibariensis / Zanzibar, is the
largest leafed variety often growing to extreme heights. Typically, the all green plant with white veining is found, though also features shades of red within the variety.

While they are poisonous, the seed pods present the problem moreso than the plant itself. Simply remove the pods before they
form and / or mature, and dispose of them properly.

Using common sense, there is no reason one cannot safely grow these tropical beauties in one season, provided a long season is available.

I'm a castor bean lover from way back. I began growing the "giants" a couple of years back and have been very pleased. The first year plants grew to over 10' with the largest leaf about 30" across. Last year, grew to almost 14' with the broadest leaf over 36" across. This year, I started my indoor garden before Christmas, currently have plants almost 2' tall, so hope to get some 20 foot'ers this year.

'Zanzibarensis' is a fast growing annual in zone 5, but my information says it is hardy in zones 8-10. It adds a very tropical look to the garden, and some people use them as a quick "tree" for shade. Soaking aids germination of seeds.
