Yep, that first one is definitely a violet. I love when my own native violets bloom. Ours are mostly yellow, and they creep like strawberries, so there's golden carpets for a few weeks here in the spring! I just love them! I wish a few more western natives were the color of yours though.
I love Trilliums too! Unfortunately so do the deer.
That one with the green streaks is really cool. I know they should be all white, but maybe you've found a variant that can be propagated. Keep an eye on the area and see if you can find more like that in the following years. Maybe you could introduce it as the next big thing!
