The deal will see close co-operation on the breeding of new Aster varieties for cut-flower production and pot-plant production.
The breeding operation will be moved to De Nachtvlinder while testing will take place at Armada.
The company also has testing facilities in South America and Africa.
Armada and its agents will be responsible for the sale and licensing of the varieties.
The companies said the move was motivated by the need to reduce costs and optimise trading activities.
The new range can be found at www.armadayoungplants.nl.
