How We Operate at Dianthus

From our base in The Netherlands, the dedicated Dianthus team oversees the handling of flowers, floral arrangements, plants, transportation, and onboard care for cruise ships. Central to delivering this service, is maintaining close, personal connections with our partners. Regular ship visits play a major role in nurturing these relationships. Additionally, we carefully choose our transporters, agents, flower wholesalers, and florists. This hands-on approach, with frequent ship visits, enables us to make thoughtful choices regarding the flowers and plants that best complement the ship’s interior.

One day, a shipping agent asked me to deliver flowers on board a cruise ship in the port of Amsterdam. I delivered the flowers, and the shipping agent placed two more orders. At that point, I told the food and beverage manager that if he wanted flowers in other countries, I could arrange for that too. That’s how we began furnishing bouquets, green plants, and various additional requests to other countries.
