One flower that will pique any gardener’s interest is the chocolate cosmos. With velvety rounded petals and dark brown centers, these unusual blooms are a deep, rich maroon. Their vanilla-chocolate scent might be their finest quality. The blossoms of chocolate cosmos (Cosmos atrosanguineus), which are similar to regular cosmos (Cosmos bipinnatus), but a little bit smaller, measuring an inch and a half across. Chocolate Cosmos, on the other hand, can grow as tall as 30 inches.
The optimal conditions for growing chocolate cosmos are full daylight and slightly acidic soil; they cannot survive in temperatures below 50 degrees Fahrenheit and will die from frost.
Light
Chocolate Cosmos enjoys at least six hours every day of direct sunlight, just like regular Cosmos.
Soil
These lovely plants will thrive in fertile, well-drained soil. A mixture of potting soil and dirt should produce decent results when growing in pots; you can add some pebbles to the bottom to guarantee proper drainage.
Water
Avoid overwatering because it might lead to the decomposition of their roots. In the summer, a deep watering once a week should be adequate unless there is a lot of rain. Between waterings, let the soil slightly dry out.
Temperature and Humidity
Avoid planting these flowers before all threat of frost has passed as they may be frost sensitive. They can tolerate humidity and prefer moist soil, but an excessive amount of water at the roots might damage the plant.
Fertilizer
Your chocolate cosmos may produce more foliage than blossoms if you fertilize too heavily, but a small amount of rose food sprayed in the spring will help these flowers develop and maintain their bright colour into the autumn.
