Tips for Growing a Chocolate Cosmos
The chocolate cosmos (Cosmos atrosanguineus) is an unusual and dramatic flower that adds a touch of the exotic to any garden. This Mexican native is actually quite easy to grow, as long as you give it plenty of sun and well-drained soil. Chocolate cosmos bloom in late summer and fall, adding color to the garden when many other flowers are past their prime.
If you’re looking for a unique and attention-grabbing plant, chocolate cosmos is a good choice. The deep maroon blooms are borne on slender stems above tidy mounds of foliage. The blooms have a pleasant vanilla fragrance that is most pronounced in the evening.
Chocolate cosmos is not often seen in gardens, which makes it all the more special. Here are some tips for growing this intriguing plant:
Site selection: Choose a sunny spot in your garden with well-drained soil. Chocolate cosmos will tolerate some shade, but it will not bloom as profusely in shady conditions.
Preparing the bed: Add compost to your planting bed before you add chocolate cosmos plants or seeds. This will help improve drainage and provide nutrients to your plants.
Planting: You can start chocolate cosmos plants indoors from seed or buy plants at a nursery or garden center. If you start with seeds, sow them on the surface of moistened seed-starting mix and place them in a warm location with bright light. Keep the mix moist but not soggy until seedlings appear, which should be in about two weeks. Once seedlings are big enough to handle, transplant them into individual pots filled with potting soil mix. When nighttime temperatures remain above 50 degrees Fahrenheit, you can plant your chocolate cosmos outdoors. Be sure to harden off yourseedlings (acclimate them slowly to outdoor conditions) before planting them in their permanent location in the garden bed.
Watering: Water your chocolate cosmos regularly during the growing season, letting the soil dry out somewhat between waterings. Once established, these plants are quite drought tolerant. Too much water can lead to fungal diseases such as powdery mildew or root rot, so be sure not to overdo it!
Fertilizing: Fertilize monthly with a balanced fertilizer during the growing season if you want your plants to produce an abundance of blooms. An organic fertilizer such as compost or manure tea can also be used. Cut back on fertilizing once blooming slows down in late summer or early fall; too much fertilizer can delay flowering or cause excessive vegetative growth that may make your plants more susceptible to winter damage.
Now that you know how to successfully grow and care for chocolate cosmos, it’s time to enjoy these unique flowers in your own garden. Be sure to give them plenty of room to spread out, as they can quickly take over a small garden bed. And don’t forget to deadhead spent blooms to encourage even more flowering. With a little effort, you can have a dramatic chocolate cosmos display that will last from summer right into fall.
