Daniel Ost (born 5 August 1955) is a Belgian floral artist, floral designer and garden architect. CBS News has described him as "the world's leading flower designer" while The New York Times says that "to call him a master flower designer is akin to calling Annie Leibovitz a shutterbug".
His clientele includes numerous royal families, sheikhs, multinational organisations and humanitarian organisations like UNICEF.
Ost was born in 1955 in the suburban town of Sint-Niklaas, Belgium, in a family of which he was the eldest of six children.
Ost and his wife Marie-Anne have two children. Maarten Ost became a children's book author living in Leuven, Belgium; he died in 2017. Their daughter, Nele Ost, is following in Daniel's footsteps as a floral designer and is currently the creative director of the company.
Daniel Ost and Marie-Anne Boeykens founded Floreal, a flower shop in Sint-Niklaas, Belgium, in 1979. The business later evolved into the Daniel Ost Group, an international floral design house active in retail floristry, event decoration, and garden and landscape design.
The Daniel Ost Group operates several retail locations in Belgium and the Middle East, including shops in Brussels, Knokke and Riyadh, and undertakes floral and landscape projects worldwide.
The company is led by Yann Callaert, who serves as Chief Executive Officer, and his daughter Nele Ost, who is Creative Director. Daniel Ost is no longer involved as an owner or in the daily management of the business and only acts in an advisory capacity on limited selected projects.
Throughout his career, Ost has published numerous books about his exhibitions, decorations and gardens. He has also been featured in numerous magazines like Elle, Vogue, Architectural Digest and Bloomberg, regarding floral design and garden architecture.
