Mazus, a slow-growing perennial with delicate blue-violet flowers, is an excellent ground cover thanks to the creeping stalks. Use this perennial to smooth the space between stones in a patio or cover the ground along a gravel or cobblestone path.
In addition, as Mazu tolerates wet soils, it is suitable for rain gardens and other planting areas that are sometimes too wet for other ground covers. Also known as creeping mazus, Mazus reptans are native to the Asian Himalayan region. The Mazus genus has 30 known species[1] that are common in temperate and subtropical regions.
