Oserian Group

History In 1969 Hans Zwager – a Dutch World War II Marine turned entrepreneur – bought a large cattle ranch on the shores of Lake Naivasha, Kenya. The estate, set in a part of the world Hans and his wife June had loved since the early 1950’s, was Oserian. They grow 80% of our flowers hydroponically. Instead of soil, we grow them in a water and mineral solution, so they can get their nutrition just right. What’s more, it helps us recycle fertilizer and reuse vast quantities of water – practices the Water Resource Management Authority (WRMA) have commended. They've also collaborated with the World Wide Fund for Nature (WWF) to improve water quality and the ecosystem of Lake Naivasha. WWF have also helped them to promote their 18,000-acre wildlife sanctuary, which is home to buffalo, zebras, giraffes, antelopes, gazelles, warthogs and leopards.
