For ornamentals, a good temperature management should start by the grower/shipper

?Domestic and offshore-grown cut flowers often arrive at transportation or consolidation facilities from 10 to 40 degrees F (5 y 24?C) above their ideal holding temperatures. Potted floral crops frequently arrive even warmer. The graph below (in the original work) shows incoming cut flower temperatures recorded for 58 growers at a California consolidation dock over an entire year. Average temperatures for each grower (diamond) were all above 43 F (5.5?C) and for some growers were nearly 70 F (21?C) , with an average of 51 F (11?C). In another series of temperature measurements taken at two Florida consolidation docks, incoming cut flower temperatures ranged from 43 to 59 F, with an average of 50 F, while leatherleaf fern averaged 57 F with 19% of the shipments over 70 F.?This quote shows the responsibility to be the first step of the logistics chain in maintaining ornamental quality. At its source, and White Paper "Improving the cold chain for cut flowers and potted plants," by George Staby and Michael Reid, continues to explain the incidence of other "actors" (transport companies, etc.).. This, without forgetting that for ornamental species of tropical origin, the optimum temperature is higher than other species.The White Paper is available at Chain of Life Network, http://www.chainoflifenetwork.org/The source of the picture is sobreholanda.com
