Bright Lights Cosmos - Radiating Beauty

Vibrant 2-3" flowers that bloom in sunset colors of red, orange and yellow. A resilient and versatile heirloom flower that tends to be very easy to grow from seed. Distinctive, filigreed foliage.

Excellent low maintenance drought tolerant flowers that prefer full sun. Do not over water! Early bloomer that lasts into the fall with a few light frosts.


Cosmos are native to Mexico. in 1838 New York seed supplier Grant Thorburn was offering his customers six-foot tall "late Cosmos" and there was little development of the species through the 19th century. The original cosmos did not bloom until late summer, so in the early 20th century new earlier flowering strains of cosmos were developed, and the blossom size was increased a bit. 


An excellent hummingbird and butterfly attractant. Also makes a wonderful cut flower.
