Re­fresh­ing look

Global Times - Weekend - - FRONT PAGE -

Rain­bow roses are dis­played at the 36th in­ter­na­tional flower expo in St.Paul, Brazil on Thurs­day. The rain­bow rose is a rose that has had its petals ar­ti­fi­cially colored. The method ex­ploits the rose’s nat­u­ral pro­cesses by which wa­ter is drawn up the stem. By split­ting the stem and dip­ping each part in dif­fer­ent colored wa­ter, the col­ors are drawn into the petals, re­sult­ing in a mul­ti­col­ored rose. These color changes to the rose make it live shorter than an un­col­ored one.
