describe

Marigold is a perennial plant commonly found in Europe, the Mediterranean and North Africa. Its flowers are orange or yellow, have a radiating shape, and usually bloom in summer.

Marigolds belong to the Asteraceae family. Native to southern Europe and the eastern Mediterranean, it has been widely cultivated and can be found in cool, temperate climates. The plant has a history of culinary and medicinal uses, and its branched stems are up to 2 feet long and covered with fine hairs. The leaves are simple, alternate, sticky and fragrant. The vibrant daisy-like flowers, ranging in color from orange to yellow, bloom until the first heavy frost and are suitable for cutting.

planting

Marigolds develop into nail-shaped achenes after being pollinated by bees. The seeds form a gray or light brown round corolla. Marigolds grow easily in well-drained soil in full sun. Sow seeds directly in the garden before the last frost, or sow seeds indoors 6-8 weeks in advance for earlier blooming. Continuous sowing results in continuous flowering. Use fresh seeds as viability decreases during storage. Germination takes 5-15 days. Pinch the vegetative buds to promote a bushier plant. Marigolds like moderate watering and light fertilization. Prune regularly to encourage more blooms. It can be grown in flower beds, parterres, cut flower gardens, containers and cottage gardens.
