One of the more unusual-looking spruces, the Weeping Serbian Spruce (Picea omorika "Pendula Bruns") will draw attention in the garden. This spruce’s trunk and branches twist and curve to form a spire reaching up to 30 feet tall. Because of the twisting growing habit, the silvery-green on the underside of the needles is revealed, creating a stunning display. Grow weeping Serbian spruce in USDA hardiness zones 4 through 8 in full sun. This shrub is drought-tolerant once established.
"Pendula" (Picea pungens "Pendula"), also known as Colorado spruce and weeping blue spruce, reaches about 1 to 2 feet in height with a spread of about 10 feet when left to curve along the ground. This evergreen dwarf with its blue-needles reaches only 6 feet tall if staked. It prefers well-drained soil in full sun but will tolerate light shade in USDA hardiness zones 3 to 7.
According to the University of Arkansas, Norway spruce is one of the most popular spruces in America. The dwarf, weeping Norway spruce "Pendula" (Picea abies "Pendula") can be trained to grow upright with the trunk and branches drooping down or left to snake along the ground. This cultivar bears bright pink cones in the spring. This slow-growing shrub is hardy in USDA zones 2 through 8. Unstaked, it may reach 3 feet tall but spread to 10 feet wide in partial to full sun.
Another weeping variety of spruce, "Nidiformis" (Picea abies "Nidiformis"), grows in the shape of a mound with a depression on top, true its common name -- bird's nest spruce. The curvature of the trunk is hidden in its dense foliage, and since pines don't take kindly to pruning, bird's nest spruce is best appreciated for its compactness that makes it good for tucking in between trees or rocks that its weeping branches can spill over. It is often used as a foundation plant. This slow-growing shrub reaches about 2 feet tall and 10 feet wide after about 10 years. Its light-green needles that are deer-resistant. Bird's nest spruce thrives in full sun in United States Department of Agriculture plant hardiness zones 3 through 7.
