Definition: In English, a Chelsea flower refers to an early blooming species of flowering plant native to the Mediterranean region. The most common Chelsea flowers are tulips, daffodils, and narcissus, which bloom between May and August. The word 'Chelsea' is derived from the Latin term "chelone," meaning "red." It was used in English as a noun to refer to an early blooming flower or plant that would appear red in color. The name 'Chelsea' has also been applied to other flowers with similar names, such as cherry blossoms and daisy. The term 'flower' refers to all types of flowering plants, including tulips, daffodils, narcissus, hyacinth, and more. However, the specific flower type or species must be specified in order for it to be identified as a Chelsea flower. A Chelsea flower can also refer to a particular period of the year, such as when a certain species blooms during that time, which is known as 'Chelsea bloom season.'
