Tagetes

Tagetes, or marigolds, is a genus in the sunflower or aster family that includes 49 species of flowering, herbaceous plants with a shrubby form that are native to Central and South America and have been introduced throughout the world. Depending on their environment and whether they are grown as an outdoor or indoor plant, Marigolds can be annuals or perennials. The plants give off a strong aroma when crushed and marigold flowers are bitter with a spicy, herbal flavor. The 'Lemon Gem' and 'Tangerine Gem' cultivars, however, are quite flavorful. The flowers can be made more palatable if you remove the bitter, white base of the petal. The plant is often used in tea, to color foods, and as a substitute for tarragon; however, it can be harmful if eaten in large amounts. The juice, sap, or thorns of these plants may cause a painful skin rash or irritation. Wash the affected area of skin with soap and water as soon as possible after contact.

The name Tagetes comes from the name of an Etruscan seer supposedly born from the plowing of the earth and refers to the ease with which plants of this genus come out each year either by the seeds produced in the previous year, or by the stems which regrow from the stump already in place. The common name, marigold, is a shortened form of "Mary's gold". Depending on species, Marigolds can range from 4 inches high to as much as 7 feet. Again, depending on the species, Marigolds grow well in almost any sort of soil with good drainage, and some cultivars are known to have good tolerance to drought. They can grow in full or partial sun, but full sun encourages blooms.

Diseases, Insect Pests, and Other Plant Problems: 

Marigolds can be susceptible to leaf spot and flower blight. Slugs can also be a problem.
