Juniperus horizontalis 'Copper Harbor' / Copper Harbor creeping juniper

Juniperus horizontalis 'Copper Harbor' is a strongly growing, flat, ground-covering selection of creeping juniper with layered, spreading branches that will root when in contact with the ground. Summer foliage is a pleasing bright-yellow that, with the change of seasons in late fall, turns a vibrant copper color with individual shoots ranging from brilliant metallic pinks to lemon yellows, depending on winter temperatures and sun exposure.

After 10 years of growth, a mature specimen will measure 6 to 8 inches (15 - 20 cm) tall with a 4-foot (1.3 m) spread, an annual growth rate of 4 to 6 inches (10 - 15 cm).

This cultivar originated in the early 2000s as a sport on a specimen of Juniperus horizontalis 'Bar Harbor' found and introduced by Blue Horizon Nursery, Grand Junction, Michigan.
