All flowers are a treasure to this Earth. They come in various different shapes, sizes, colours and patterns. My favourite, however, is definitely the rose. While it does appear in many colours, the bold red rose is the most popular across the world to symbolize love. Roses grow in the form of shrubs. They have small thorns all over their stems to protect themselves and harm those who are greedy to pluck them. Their petals are soft and delicate. The other colour variants of roses include white, pink and yellow. White roses are said to symbolize peace, yellow roses indicate friendship and pink roses are a symbol of gratefulness and joy.
