Dr. Magana Njoroge Mungai acquired Magana Farm in the late sixties. He initially began with diary farming. In the seventies he switched his focus from dairy farming to horticulture: growing french beans, avocados and later on apples. In 1994, he added floriculture to his farming portfolio and began to grow roses.
This switch resulted in the birth of Magana Flowers Kenya Limited. It is a 18 hectare, 550 employee flower farm that grows roses for export. Dr. Magana Njoroge Mungai its founder is also its current Chairman and CEO. The flower farm is located on Magana Farm in Kikuyu, Kenya which is approximately 18 km from the city centre and west on the Nairobi- Nakuru dual-carriage highway. It is located 30 km from the International Airport.

Its location in Kikuyu is approximately 2000m above sea level thus providing for good geographic location, favorable climatic conditions, and mild to warm temperatures required for growing quality roses. Fresh and clean water is also available in abundance. There are 18 hectares of planted roses developed in 6 phases.

Magana Flowers Kenya Limited is a fully owned subsidiary of Magana Holdings Limited which is a privately owned company incorporated in Kenya in 1973. Magana Holdings Limited also has interests in real estate, coffee farming, information technology and investments. Magana Holdings is owned by Dr. Magana Njoroge Mungai and his family.
