Every day from dawn, a fleet of forklift trucks carries crates of roses, tulips, chrysanthemums and 22,000 other flower varieties through the world's biggest flower market.
Yme Pasma, chief operating officer for Royal FloraHolland, keeps a watchful eye as workers sort stems arriving from all over the world before sending them off to destinations across Europe.
But this well-oiled operation, where robotic efficiency meets a riot of colour and fragrance, is facing a challenge that could make the hardiest bloom wilt: Brexit.
"We are preparing for all kinds of disturbances along the way," Pasma told AFP at the huge warehouse in Aalsmeer, near Amsterdam. "The worst is a hard Brexit and we are preparing for that as well."
