For a Chinese funeral, it is best to send a wreath or flower arrangement of white and yellow chrysanthemum. For a more traditional Chinese funeral, thorny flowers such as roses should be avoided. And when the deceased are more than 80 years old, brigher flowers are appropripriate. Ribbon banner naming the senders and their relationship to the deceased are often draped across the arrangement. Usually the banner is written in Chinese, so ask ahead if the florist can provide Chinese calligraphy service.
Often time the obituary notice may say “No Flowers” This is more often just a directive to the general public. Extra flowers from the general public may require extra transportation expense to move the flowers after the ceremony. Closed families and friends are often okay to send flowers but just check with the family to make sure.
