Juniperus horizontalis 'Lime Glow' (Lime Glow Juniper)


Michael's Opinion

Lime Glow Juniper is an excellent ground cover with its lime green foliage, vase shape and fast growing habit. It prefers dry, sandy soils, making it perfect for rock gardens and foundations. It is also pollution tolerant for city environments and a very low maintenance plant with only light pruning required to control its spread.
