cultivating bunchberry and uva ursi

This doesn't quite fit under wildcrafting but I wasn't sure where to ask about this.  We'd like to cultivate some bunchberry and uva ursi in our yard, but don't feel comfortable collecting whole plants from the wild.  Is there a way they can be propagated easily?  Or somewhere we could purchase them?

I don't know about bunchberry, but you can get Uva Ursi seed from Horizon Herbs or whole plants from Richter's Herbs.

Here in Portland I have found several nurseries that carry both Bunchberry and Kinnikinnick.  I normally see them selling for about $5-6 for or $10-15 for gallon pots and they are offered in native plant sections.  Kinnikinnick is pretty easy to cultivate and many people have it in their yards (even though some seem to be Artctostaphylos hybrids).  I've got one in my garden and it's been pretty happy without any special considerations.  I've been wanting a Bunchberry myself but know little about growing it.  I see them growing as understory plants in the forest so would probably put them somewhere shady and moist myself.
