Know before you buy
One pack of Cosmos 'Bright Lights Mix' covers approximately 10 square feet. Given the mature height of 2 to 3 feet, ensure you have enough vertical space for these plants to reach their full potential.
Yes, this variety is quite hardy and performs well in dry conditions once established. While they appreciate moderate watering, they are a great choice if you are looking for drought-tolerant annuals.
Cosmos are excellent cut flowers. For the longest vase life, harvest them in the morning when the blooms are just beginning to open and place them immediately into clean water.
While these cosmos have an extended bloom season through fall, deadheading spent flowers can encourage the plant to produce more blooms. However, if you want to attract finches, leave the mature seed heads on the plants at the end of the season.
Because these plants reach 2 to 3 feet in height, they can be grown in large containers, provided the pots have adequate drainage and receive full sun. Ensure the container is deep enough to support their root system.
These seeds should be planted very shallowly, at a depth of about 1/16 of an inch. They require light to germinate, so be careful not to bury them too deeply in the soil.
