Generally speaking, white flowers express mourning, white chrysanthemums, Bai Baihe and calla lilies are more suitable for grave-sweeping, while white roses, gardenias, Bai Lianhua or plain flowers symbolize regret and nostalgia. Others like simple and tough plants, such as Pinus bungeana, gladiolus and weeds. Yellow flowers can also express condolences, among which Huang Juhua is the most common one.
Of course, there is no need to stick to this. You can choose flowers according to the age and preferences of the deceased. You can also choose forget-me-not, yellow roses, red roses, birds of paradise and other flowers. If the old man dies, the proportion of red and pink flowers can be appropriately increased. These warm colors can better reflect the yearning of the younger generation. It should be noted that if there are no special circumstances, it is best not to use flowers with strong fragrance and bright colors, so as not to give people the impression of disrespecting the dead.
