The cold chain is the sequence of steps in which cut flowers stay at a low temperature: from grower to market, from market to workshop, from workshop to venue. If it breaks, for example in a van left in the sun, the flowers open too early or wilt.
It matters most with imported flowers, which travel longer, at August weddings and at large events with many arrangements prepared in advance. The guide on flowers for large events covers logistics and cold rooms; the one on the summer wedding covers delivery times; the one on where flowers come from describes the Italian supply chain and imports.
What to ask: where the flowers are kept in the days before, how they travel, and whether the venue has a cool room to store them.
