A fellow blogger, Daniela from Bratislava on her blog, MIMI A JEJ SVET (Mimi and her World) posted some photos of invasive sunflowers a few weeks ago. I thought that the same sunflowers grew in Santa Fe. Alas, no. The sunflowers that grow here have a different petal shape.
The flowers above look like they're related to coreopsis and are an allergen. Someone at the dog park said they're related to ragweed. Ahchoo!
I took the photos outside of my office on a windy day with my phone so unfortunately they're blurry.
