Restharrow, Ononis repens. Watering needs? Where it grows? Its hardiness (how cold can it get)? where can i buy some?

I've grown arctostaphylos uva ursi in NH-USA, it never grew much in a raised bed isolated to itself. My take was this was an alpine plant (like a heath) what did I get wrong?

Hi Tom,
I must admit that I'd not heard of these two, so it gave me an opportunity to do a little searching.
It does look like the info on the Ononis repens is a bit incomplete, but it may answer couple of your questions...Though where to buy it is not one of them...sorry.
