It's a shame it isn't in Santa Rosa, which is only 7 miles from my house, but I do order from Santa Rosa Gardens every year when they have their sale, so I probably will order it from them this year.
I said I've never seen it locally, but the truth is that I've never looked for it locally. It may be offered by every nursery here.
I tend to buy only groundcover plants, so that they can fill the spaces between my roses without obscuring them. This looks like a good candidate to take the place of an ailing rose bush, however.
