I found yellow ones and purple ones. Please review the attached images and let me know what the yellow ones are and what the purple ones are? Thank you in advance!
The second is definitely the Columbia Gorge endemic, Lomatium columbianum. The first, hmm... all my native plant books are at work. Might take a bit of time to get back to you on it. Are you familiar with Russ Jolley's Wildflowers of the Columbia Gorge? That has an excellent cross-referencing on locations / habitats / species. Also, Flora and Fauna Northwest is top notch for the Columbia Gorge flora. You can look back on previous years with blooming records and locations to narrow down possibilities quite quickly.
Hello Daniel, Thank you for your reply. I just got "Plants of The Pacific Northwest Coast" which was recommended by many people. I will try to get the "Wildflowers of Columbia Gorge" as well. Thank you! And thank you to all of UBC gardening forum. I used to come on this forum when I was a teenager to learn about plants and everyone's knowledge has helped me significantly!
