Lake Naivasha cut-flower cluster
Lake Naivasha cut-flower district is situated about 100km northwest of Nairobi, in
the Great Rift Valley, at an altitude of 1800-2000m above sea level, and it
comprises an area of 2000 ha including the municipalities of Naivasha, Thika,
Kiambu/Limuru, Nairobi, Nakuru, Nakuru, Nanyuki/Nyahururu, Eldoret, and Mt.
Kenya region.
About 50%-70% of the Kenya’s total cut-flower production is concentrated around
Lake Naivasha, involving about 150 horticultural firms.
In 1970s the principal cultivation in Kenya was fruit and vegetables for local
consumption and export; the region was also specialised in the production of
coffee beans, whose prices in the international markets collapsed during 1980s. In
that period some local entrepreneurs decided to search for new profitable
businesses and entered, first, in the cut flowers production, and, subsequently, in
the cut roses (1990s).
The cut-flower production started in Limuru, where local summer flowers were
growing spontaneously.
The oldest local farms (Oserian, Homegrown and Sulmac), were founded during
the 1970s.  Some years ago Flamingo Holdings (the present parent company of
Homegrown) acquired Sulmac, which today operates the farm under its new name
Kingfisher.

Oserian’s History
Oserian, “Place of Peace” in the Maasai language, is
located on the Moi South Lake Road, Lake Naivasha.
It is the largest flower farm of its kind in Kenya,
established in 1969 as a vegetable growing farm, with a
5 hectare area of production and a workforce of six
employees.
Oserian started cut flower production in 1982; today,
with over 20 years strong growth, is a ‘leader in its
field’ and the largest multi – crop farm in Kenya. It
employs 6,000 people and has 225 hectares of
production.
Roses
Oserian was one of the first farms to
commercially grow and export roses to Holland
from Kenya in 1984.
Starting as a relatively small operation, roses are
now a main crop of Oserian with 84 hectares
dedicated to them.
With an average of 64,000 plants per hectare,
Oserian exports 3.5 million cut flower roses per
week in nine different colour categories, from
over twenty different varieties.
Carnation
Carnations (Dianthus) are the world’s third most
popular cut flower.
Oserian began growing carnations in the late 80’s,
becoming commercially productive in the early
90’s.
Now with 93 gross hectares, Oserian produces on
average 3.5 million stems per week for export
and is now the Largest Spray Carnation Farm in
the world.
Statice & Gypsophila & Lisianthus
Statice – Limonium Sinutum was the first crop to be
grown at Oserian. Statice’s unique branches are in
demand as a filler material for bouquets, corsages,
baskets and other flower arrangements, the other
benefit being its ‘ever lasting’ nature.
Gypsophila Paniculata (Baby’s Breath) is used as a filler
in many of Oserian’s Packed At Source (PAS) bouquet
product.
Oserian started to grow Lisianthus in 2003. The crop is
now grown in an area of 6 hectares in heated
greenhouses using the Geothermal Heating capability.
The supply chain
 
 
Breeding, Propagation and TC Lab
    
    
The first stage of the 'seed to sale’ Oserian concept
   
and process. Either through 
 
internally based TC Lab
   
or with associations with breeders and propagators,
   
decisions are made on crop, volume, colour mix,
   
variety and plant behaviour.
 
 
Oserian Growing and Harvesting
    
    
 
 
Oserian's growing techniques,including hydroponics
   
 geothermal heating and CO2 enrichment come
   
 together with a dedicated, trained and committed
   
 workforce to ensure a top quality product.
 
 
Grading
    
    
 
 
Product once at the Packhouse is graded and the
   
Cold Chain
’ begins. Stringent measures, protocols
   
 and sophisticated systems allow for quick and 
 
   
 accurate grading to stem length, head size, foliage
   
 removal, colour mix accuracy and other market
   
 requirements.
The supply chain
 
 
Processing and Packing. Packed at Source
    
    
Bouquets are Packed At Source in line with strict
   
customer specifications.  This involves value 
 
   
addition by adding sleeves, flower food, labels and
   
barcoding.
 
 
Dispatch to Nairobi
    
    
All products are fully traceable through every 
 
   
process back to the field. Packed and fully labelled
   
they are pre-chilled to specific temperatures – part
   
of the ‘Cold Chain’. After a final quality check boxes
   
are placed on the refrigerated Oserian trucks and
   
taken by road to Nairobi JKIA.
 
 
Flight and supply of Product
    
    
 
 
At Oserian Nairobi, product is prepared for air 
 
   
 shipment and destined for supermarkets and 
 
   
 auctions. Temperature and quality control checks
   
 ensure prime conditions so that a top quality 
 
   
 product is received by the customer.
Mavuno Group
The Mavuno Group is a
conglomerate of companies
incorporating services in the
areas of flower breeding,
propagation, production,
marketing and logistics.
With a company history
stretching back more than
30 years in producing,
sourcing, supplying and
trading in the global fresh
flower industry, Mavuno
provides an integrated
supply chain from the
grower source to all market
segments and customers
worldwide.
Mavuno Group has seven
companies employing more
than 6,000 staff working or
trading in over 60 countries.
Technology - 1
Nature’s Geothermal: 
Oserian’s vision was to have a technological
growing capability that was as advanced as the Dutch growers with
full climatic control of the greenhouses, so it initiated a major
investment programme to harness the geothermal energy (it is a
heat and power resource that is clean and reliable) from existing
geothermal wells located on the Oserian land in 2003.
Oserian is unique through combining geothermal and solar energy
and advanced farming techniques in its product operations.
Oserian is today one of the most technologically advanced flower
farms in the country: the new 50 ha Rose project employing
geothermal heating and carbon dioxide makes it 
the largest
Geothermal Greenhouse Heating Project in the world.
Oserian now uses geothermal steam to produce 2 MW of electricity
making the farm self sufficient in energy.

Technology - 2
Hydroponics
: it 
comes from Latin and means "Working Water".
With hydroponics the plants are grown in an inert growing medium
(it is simply what the roots of the plants are growing in, an inert
substance that doesn't supply any nutrition to the plants), the
plants do not get anything from the growing medium. The plants
receive only what you give them, nothing more, you have complete
control over pH, nutrients (solution of water and fertilizer mixed)
and the nutrient strength.
Top quality production (better grade profile, larger bud size, stronger
colours, larger leaves)
Reduction of pesticides/fertilisers
The ability to produce higher yields
Water conservation and 
less wastage
Better control and greater uniformity
Technology - 3
TISSUE CULTURE LABORATORY
In 1992, as Oserian continually developed and
expanded in cut flower production, the need for
improved control over cultivation and the
importance of having a uniform and clean
starting crop were the main drivers behind the
establishment of the Tissue Culture Laboratory.
Oserian’s Tissue Culture provides premium
tissue culture plants for export and local
markets.
Technology - 4
Integrated pest management
The four biggest problems in cut-flower growing
operations are pests: thrips, red spider mites, root
knot nematodes and leaf miners.
Oserian collaborates with Real IPM in order to
apply IPM in a couple of greenhouses. 
To date,
red spider mite reduction is a major success;
this pest was previously controlled with toxic
acaracides.
Environment
“Oserian is a leader in wildlife and environmental conservation and the sustainability of Lake
Naivasha and its environs”
Water and Waste Management:
Oserian’s Wetland: 
modernised wetland to purify the Packhouse run off water as well as collection of
natural rainfall. The wetland comprises of a gravel–bed and three ponds designed to process this water by
filtering naturally in order to make it suitable for return to the Lake; 
Forestry: 
planting of trees, general landscaping and gardening are important aspects of Oserian, that has a 1
hectare nursery which supports the indigenous species program, an exotic species program, a threatened
species program and Oserian donations of seedlings to the community.  
Oserian Wildlife Sanctuary (Ows) & game coridors:
 all profits generated by tourism to the Sanctuary
are dedicated to the conservation of this area and the wildlife it supports. The Sanctuary has, for
example, utilised these profits to both reintroduce several endangered species such as White Rhino
and Grevy Zebra as well as introduce non-indigenous species including Beisa Oryx, Greater Kudu (all
trans-located from Northern Kenya), Wildebeest and Topi (from the Mara region). Oserian Wildlife
Sanctuary’s resident Cheetah population continues to thrive.
Naivasha & Environs:
 any project undertaken by Oserian is first assessed through an EIA
(Environmental Impact Assessment) that means a systematic examination to determine what
adverse impacts on the environment a programme, activity or project may have. It is a tool for
protecting the environment and ensures that environmental impacts are considered during the
conception and design of any development activities, alongside economic, technical, institutional
and social impacts of the up-coming project. Adverse impacts are mitigated. It is also a mechanism
to ensure that a development project is designed to comply with existing environmental laws and
standards.
