3.
4.

 

I have suggestion for first three
1. Erigeron linearis
2. Balsamorhiza hookeri
3. Nothocalais troximoides

 

Nadia - you seem to be simultaneously asking for ID and providing ID - is it confirmation you are looking for?

 

Yes, I want to know if I found ID correctly. I didn't know these plants but I found a very good site
Wildflower Search
Hope, some ID's are correct

 

Thanks for that, Nadia. I have added a link for it to the Pacific Northwest Native Plants Resources page and the Apps for Mobile Devices page. And to my old thread on Search for IDs by characteristics.

 

Yes to 1 and 2, I don't know my Nothocalais very well, but that is the genus.
