Marigolds are one of the most popular annual flowers that are easy to grow or transplant. When planted in suitable condition, they overflow with bright blossoms and fills the garden with cheerful colour. Marigolds are equally suitable for containers, as they are in the garden and are even grown as long-lasting cut flowers with a clean, crisp scent. The varieties of Marigolds have different colours like attractive yellow, orange, or red composite flowers.
