Vase life and floral characteristics were studied for Rosa hybrida (cvs. Forever Yours, Briarcliff Supreme, Red Garnette, and Rose Elf) flowers grown in atmospheres containing 300 ± 200, 1000 ± 300, and 2000 ± 500 ppm CO2 for at least half of the daylight hours. Only ‘Red Garnette’ flowers grown in CO2-supplemented air had significantly longer vase life (one-half day) than those produced in normal atmospheres.
