Go to the site of the Educational Concerns For Hunger Organization (ECHO) and check out their seed bank. They have seeds for all over the world, with descriptions of what they will and won't tolerate in soils, climate, rainfall, heat, etc.

Be sure to check out the ENVIRONMENT KEY page to understand the climate codes in bold beside the seed descriptions. You must be a member to have access to the seeds.

Thank you, but I would like to get in touch with someone in South Africa that is involved with this and knows what to do.
