Marigolds come in different colors, yellow and orange being the most common. Most of the marigolds have strong, pungent odor and have great value in cosmetic treatment. There are many varieties of Marigolds available today.Some of the major Marigold varieties are listed below:
- African or American Marigolds (Tagetes erecta): These marigolds are tall, erect-growing plants up to three feet in height. The flowers are globe-shaped and large. Flowers may measure up to 5 inches across. African Marigolds are very good bedding plants. These flowers are yellow to orange and do not include red colored Marigolds. The Africans take longer to reach flowering stage than the French type.
- French Marigolds (Tagetes patula): Marigold cultivars in this group grow 5 inches to 18 inches high. Flower colors are red, orange and yellow. Red and orange bicolor patterns are also found. Flowers are smaller (2 inches across). French Marigolds are ideal for edging flowerbeds and in mass plantings. They also do well in containers and window boxes.
- Signet Marigolds (T. signata 'pumila'): The signet Marigolds produce compact plants with finely divided, lacy foliage and clusters of small, single flowers. They have yellow to orange colored, edible flowers. The flowers of signet marigolds have a spicy tarragon flavor. The foliage has a pleasant lemon fragrance. Signet Marigolds are excellent plants for edging beds and in window boxes.
- Mule Marigolds: These marigolds are the sterile hybrids of tall African and dwarf French marigolds, hence known as mule Marigolds. Most triploid cultivars grow from 12 to 18 inches high. Though they have the combined qualities of their parents, their rate of germination is low.
