I think the fuzzies are the start of more new buds that will open in several more days. The Arrowleaf will sometimes cover whole hillsides with their large blossoms. Their roots are tuberous and the Indians in this area valued them very much as a food source, somewhat similar to potatoes.
The ones in your area probably have not reached full maturity yet and these had a head start. I’m always amazed at their growth rate in spring. Seems like they just pop up and bloom quickly this time of year.
The sunflower family is huge and some of the plants are surprising. These are easily identified by their size, their leaves and the way they grow in big bouquets. I will try to remember this summer to try eating the roots: they are supposed to be quite good.
