Blue Rug Juniper
This is one of the most popular ground cover junipers in America.
Blue Rug Juniper has a medium growth rate with a low prostrate habit 4-6 inches high with a spread 5-8 feet wide.
It is also tough, deer and drought tolerant and able to survive being walked on with minimal damage, if any.
To get a good dense mat, plant them 2-3 feet apart.
Blue Rug needs to be planted in full sun.
