552-001D4 Juniperus communis 'Compressa'
Sun Zones 2, 3, 4, 5, 6, 7, 8
Juniperus communis 'Compressa' appears like a narrow blue exclamation point in the garden. This upright, slow-growing, dwarf conifer is an excellent addition to the mixed border, as well as in troughs and containers. Its verticality and its neutral blue green compact foliage make it a very versatile element for small or large gardens.
One of the surprises from our experiences growing Juniperus communis `Compressa' in our display gardens is its performance under different conditions.
In one place we grow Juniperus communis 'Compressa' in a low water requirement gravel garden (watered 3 times a summer) with very little organic matter available in the soil which in summer is baked by the sun from after 11 a.m. until sunset. Here the plant grows about 3"-4" a year, is no more than 8" wide and 42" tall after nearly 8 years and the foliage is loosely compact.
In another full sun garden where the well drained soil is top dressed with aged hemlock bark compost and the plant receives irrigation about once every two weeks in the dry parts of the summer (July-Mid September) the plant grows quite differently. In this bed, the plant grows about 6" a year, is nearly 18" wide and 8' tall after about 8 years and the foliage density is very compact. I notice that many customers reach out and touch the foliage to feel and better the texture. 72 in. x 18 in.
