7-Petal Yellow Hawkweed: The 127th Flower of Spring & Summer!

(Please scroll down to see two more pictures!)

Oh look! It's another Hawkweed! :D Yesterday I posted a picture of the Pacific Northwest native White Hawkweed, but today I'm posting the third yellow Hawkweed species I've found on our property! There are over 10,000 species listed to date! One of the reasons there are so many is because this plant hybridizes easily between species and this new mix is considered to be a new species! It's notoriously difficult to identify many species from one another. On top of that, they have different numbers of petals, even within the same species, and that can be seen here in these flowers as well.

If you would like to know more about this flower, Wiki has two sources:
Wiki: Hieracium
Wiki: Hawkweed

NOTE: I'm definitely NOT an expert so I could easily be wrong about the identification of this flower!! It's really hard to know and I haven't found any flower that looks like this but a hawkweed! Please let me know if you have a better idea of what flower this might be.
