Now I understand why the seeds I sowed months ago did not bloom until recently -- day length! I kept fertilizing them, thinking that was the problem, but it only seemed to make them taller -- once again, now I know why. I will watch for seedlings next summer. Thanks for a great article, Carrie!

Ditto- Very interesting on what I used to think of as common Cosmos. Now I know why mine bloomed so darn late.
I've seen some beautiful stands of them (bipinnatus) along the highways. Great stands of purple, pink and white which can be recognized by anyone who's grown them from packets. So they must be easy for wildflower sowing.
Thanks for the article!

Yes and yes! Gwen, fertilizer will not make them bloom and is usually not needed except for the frilliest types. Sally, your swaths of purple pink and white sound gorgeous! Thank you both.
