What are cosmos?

Cosmos are flowering plants in the genus Cosmos, belonging to the sunflower family Asteraceae. They are native to Mexico and Central America, and are widely cultivated in warm temperate and tropical regions worldwide for their colorful flowers. The word cosmos literally means “harmony”, “order” or “ornament”, and it was inspired by the observed movements of the planets (which Ancient Greeks believed were gods).

How to plant cosmos

Cosmos are a bright and cheerful annual flower that is easy to grow from seed. They come in a variety of colors including white, pink, yellow, and orange, and they make excellent cut flowers. With proper care, cosmos will bloom continuously from early summer until the first frost in fall.

Since cosmos are such easy-care plants, they are often grown as annuals. However, in warm climates where the winters are not too harsh, they may be grown as perennials. Cosmos are native to Mexico and Central America and they will not tolerate freezing temperatures. If you live in an area where the winters are very cold, you will need to treat cosmos as annuals and replant them each spring.

If you want to try growing cosmos as perennials, the best way to do it is to start with young plants or seedlings rather than seeds. Seeds of cosmos will usually not survive the winter unless they are planted very late in the season (August or September). It is also important to choose a perennial variety of cosmos such as ‘Cosmea’ or ‘Sonata’ rather than an annual variety such as ‘Sensation’.

When planting cosmos, choose a location that receives full sun for at least 6 hours per day. The plants will also tolerate partial shade, but they will not bloom as profusely if they do not get enough sunlight. Cosmos prefer well-drained soil and they will not tolerate wet feet so make sure the location you choose does not stay soggy after a rainstorm.

To plant cosmos, dig a hole that is twice as wide as the roots of your plant but no deeper. Amend the soil with some compost or manure if it is very sandy or claylike. Gently loosen the roots and spread them out in the hole before covering them with soil and watering thoroughly. Once your plants are established, they will need very little care other than occasional watering during periods of drought. Deadheading (removing spent blooms) will encourage your plants to keep blooming all summer long.

How to care for cosmos

You can also cut the plants back by half after they have bloomed to keep them looking neat and tidy. If you live in a cold climate, you will need to dig up the roots and store them indoors over winter.
