3/12/08 Fair Trade Flowers, International Herald Tribune. From Kenya's Rift Valley, Longonot Horticulture exports 90,000 rose stems a day. Its rose bushes come in red, yellow, orange, white,pink and cerise. Whatever color bunch a London or Copenhagen supermarket needs, it will provide pronto. Flower production has grown rapidly here. Longonot started with just 10 acres of roses in 2002; it now farms 60 acres. "The conditions are right," Harry Milbank, the general manager, told me. "You've got many hours of sunlight and high altitude coolness. If it's too hot, the rose bolts. It puts out a flower with a small head."
