Juniperus horizontalis 'Bar Harbor'
Overall Description
Bar
Harbor is a very low growing, spreading groundcover juniper rarely
getting more than 6"-8" from the ground. Foliage color is bluish green,
but turns a very distinct, pronounced, purplish color in winter or cold weather. Winter coloration is especially displayed in very windy locations. First discovered
in Mt Desert Island, Maine and has shown a very high tolerance for salt
spray. Makes a fine groundcover, with good solid coverage. Easy to
grow, and quite hardy.
Typical spacing for most groundcover applications will vary be about 2 1/2 - 3 feet apart, but will vary slightly depending upon exact location, sun exposure, etc.
Plant Facts & Specifications
Mature Height: 6-10 inches
Mature Width: 6-8 ft
Growth rate: Moderate ( 6"-8" avg per yr )
Hardiness Zones: 4-9 ( if unsure of your zone, please use zone finder below )
Sun Exposure: Full sun to light shade - adapts to a wide range of conditions. Growth rate will be slightly slower in shadier spots.
Soil Preference: Will adapt to virtually any soil that has adequate drainage - does not like wet, swampy conditions. Has also shown to adapt well to rocky soils & banks.
Foliage Color & Texture: Bluish green foliage turns a very striking purplish / plum color in winter....especially in cold climates with high wind exposure. Winter coloration dissipates with the onset of warmer temps & weather in spring. Has a slightly softer texture than many other juniper varieties - not nearly as prickly.
Flower, Cone, Or Berry Facts: None to mention.
Diseases / Insects: Phomopsis can be a problem...especially if kept in very moist conditions for extended periods of time. Spider mites have also been seen occasionally on this variety.
Fertilization / Feeding: Either
water soluble ( Miracle Gro, or equivalent ), or granular ( Holly Tone
is excellent ). Other granular types with 6-12-12, or 10-10-10 ratio is
acceptable. Best to fertilize in early spring, and again in mid fall -
avoid feeding during hot summer months, and directly after
transplanting.
