Calendula is a plant. The flower is used to make medicine.

The calendula was a commonly used herbal plant in the medical system of many ancient civilizations. Calendula is a member of the plant family Asteraceae. This plant is commonly cultivated in gardens as an ornamental herb, being at times known as the pot marigold or the garden marigold in some places. The calendula herb must not be mistaken for plants belonging to the genus Tagetes - which are the true marigolds and very commonly cultivated as garden ornamentals. 

The calendula is an indigenous plant species of the southern European region. These days, calendula is cultivated in many temperate regions of the world for use in many processes and is naturalized in temperate North America and Asia.

Ideal soil profiles for the growth of the calendula are light to sandy and moderately rich soils. The soil must be fairly moist with a good drainage without water logging. The calendula tolerates a pH range from an acidic 4.5 to a very alkaline 8.3.

For best growth, the calendula prefers sites with full exposure to sunlight, though the plant will tolerate light shade.

The calendula is very easily grown from stored seed. The seeds of the calendula can be sown in the garden on the advent of spring, only when all danger from late frost has disappeared. The calendula seeds can be planted to a depth of six mm or a quarter inch deep in the soil. The seedlings of the calendula normally emerge from the soil in eight to twelve days time.

Once they germinate, calendula seedlings must not be subjected to transplantation, as this procedure mostly results in the wilting and death of the large succulent leaves. When the seedlings emerge, they can be thinned out so that forty to fifty cm-16 to 20 inches of space exist between each of the plants. This spacing will result in optimum utilization of space by the growing plants. When the calendula plants are growing, the side branches must be pruned away from time to time to encourage taller growth and to induce larger blooms in the plants. To keep the plants in full bloom throughout the summer, the dead flower heads must be removed from each plant from time to time. These measures will ensure that the plants grow at an optimal rate and produce the best flowers. Calendula plants will self sow if they are left undisturbed at a site where they are growing. The calendula is normally free of plant pests and resistant to diseases.

The calendula can be placed in pots for keeping inside the house in midsummer. Plants must be brought indoors several days in advance before the estimated coming of the first frosts in the fall. When calendula plants are placed indoors, the plants will need a minimum of five hours exposure to direct sunlight daily, which can be substituted by twelve hours of exposure to strong artificial light a day. As root rot can result from excess water, plants must not be watered too often. Ideally, the soil in the pot must be kept moderately moist at all times.
