Corn Marigold: A Bright and Beneficial Flower
Corn marigold (Chrysanthemum segetum) is a beautiful and easy-to-grow annual flower that adds a splash of color to gardens and attracts beneficial insects.
Appearance and Growth Habit
Corn marigold is a member of the daisy family and produces bright yellow, daisy-like blooms that can reach up to 2 inches in diameter. The flowers are borne on upright stems that can grow up to 20 inches tall. The leaves are long and narrow, and they are a deep green color.
Corn marigold is an annual plant, which means that it completes its life cycle in one year. It is native to Europe and Asia, but it has become naturalized in many other parts of the world.
Growing Conditions
Corn marigold is a very adaptable plant that can grow in a variety of conditions. It prefers full sun, but it can also tolerate partial shade. It is also tolerant of a wide range of soils, but it prefers well-drained soil that is not too alkaline.
To grow corn marigold, simply sow the seeds directly in the garden in the spring. The seeds should be sown about 1/4 inch deep and spaced about 6 inches apart. Water the seeds well, and keep the soil moist until the seeds germinate.
Once the seedlings have emerged, thin them out so that they are spaced about 12 inches apart. Water the plants regularly, and fertilize them monthly with a balanced fertilizer.
Benefits of Corn Marigold
Corn marigold is a beneficial plant for several reasons. First, it is a good source of nectar and pollen for bees and other beneficial insects. Second, it is a host plant for the painted lady butterfly. Third, corn marigold is a natural insect repellent. The leaves contain a compound called pyrethrum, which is a natural insecticide.
Corn Marigold in the Landscape
Corn marigold is a versatile plant that can be used in a variety of ways in the landscape. It is a good choice for borders, cottage gardens, and wildflower meadows. It can also be grown in containers.
When planting corn marigold in the landscape, be sure to choose a location where it will receive plenty of sun. The plants should be spaced about 12 inches apart. Water the plants regularly, and fertilize them monthly with a balanced fertilizer.
Harvesting Corn Marigold Seeds
Corn marigold seeds can be harvested in the fall. To harvest the seeds, simply wait until the flowers have faded and the seed heads have turned brown. Cut the seed heads off the plants, and place them in a paper bag. Allow the seeds to dry for a few weeks, and then store them in a cool, dry place.
Conclusion
Corn marigold is a beautiful and beneficial flower that is easy to grow and care for. It is a great choice for gardeners of all levels of experience.
