I'm looking for a low maintenance ground cover for a section of my yard. My parents live in Delaware and have Microbiota decussata which would be ideal. However, I am unable to find it down here and no one seems to know what I am talking about. The plant encyclopedia my mother has says it is suitable for zones 5-11. Does anyone know anything about this plant? If it isn't suitable for this area, are there any good substitutes?

Thanks,

Andy
