I have a problem with quackgrass, and now that I've weeded much of it out, I need a groundcover to put in its' place. I live near San Francisco and would prefer something either drought tolerant or with a low water requirement, as we have 3-4 months each year of summer and autumnal drought. I have snow-in-summer and white alyssium already, but would like something that can fill in an area more quickly.

Thanks in advance,
