Oserian Development Company
Industrial supplier in Naivasha
The institution that put Kenyan roses on the world's tables, founded on the shores of Lake Naivasha in 1969 by the Zwager family with six employees and five hectares. Oserian grew into one of the largest flower farms anywhere, pioneered sustainable bloom farming, and runs the world's largest geothermal-powered greenhouses and flower packhouse — earning AIPH's best cut-flower grower title and Kenya's best renewable-energy company award before its flower arm passed to new ownership in 2021.
