There are a lot of these Goldenrod flowers around the trails in Maple Grove. Technically called Solidago from the family Asteraceae. They add a nice touch to Fall. The white seed feathers look striking when lit with the sun. Goldenrod flowers are also known as butterweed, congleweed, golden ragwort, sqawweed, wild valeria, or golden groundsel(source). Wikipedia has a massive article.

These are not ragweeds; I don’t have photos of them, but How Stuff Works has a great depiction of what a ragweed plant looks like. Ragweeds are the weeds that cause so many people allergy problems. Ragweed has more branches of flowers, and the leafs are shaped differently. I’ll have to add ragweed to the list of photos I need to take!
