When I lived in the Seattle Washington area, it was a mere 2 hour drive to get up into the dry Wenatchee Mts (a spur off the Cascades), where there was lots of Lewisia tweedyi in some strong yellow and peachy-yellow shades (the guys at Grand Ridge Nursery found forms that were yellow strongly tinged red). From there we'd move along to another area, and my wife and I would go "rediviva" spotting, along with Fritillaria pudica, Sisyrinchium douglasii, eriogonums and penstemons... all the good stuff, and astragali too, but the most memorable plant is Trifolium macrocephalum; dwarf but with enormous heads in orange shades rather than the more typical pink, but nearly ungrowable as I've tried it. In the first link, the flowers are salmon color, but not quite as orange sunset-hued as the plants I remember in the Wenatchees. Does anyone grow this successfully.
