The only common groundcover I am aware of that produces orange/yellow salmonberry-like berries is Rubus calycinoides or creeping raspberry/crinkle leaf creeper. Easily one of my favorite groundcovers - very tolerant of foot traffic, evergreen, drough tolerant when established, adapatble to a range of site conditions and a rapid spreader yet remaining well-behaved. And produces a very tasty berry :-)

That's it! Thanks so much gardengal! I'm definitely going to get some. I might try taking some cuttings from outside work here and put it in some water... not sure if it'll take.
