It’s time to give away another vintage seed packet! Today’s prize is the cosmos packet.

The front of the seed packet depicts a trio of cosmos in delicate white, pink, and red. The back of the packet describes the flower in more detail:

None of our autumn flowers are more prized than these graceful and brilliant garden plants. It has long stem and feathery foliage, and continues to blossom in fall till freezing weather.

To win the cosmos seed packet, all you have to do is answer one question: In addition to the United States, cosmos are native to which North American country?

Send your answer, along with your name and mailing address, to uspsstamps [at] gmail [dot] com. One winner will be selected at random from those who answer correctly. The deadline for entries is 11:59 p.m. EDT Wednesday, May 22. Good luck! (Note: No seeds are included with this vintage packet.)

This contest is now over. The correct answer is Mexico. Congratulations to our randomly selected winner, Margaret Branca of Pingree Grove, Illinois. Thank you to everyone who entered.
