Tree Picea omorika [Serbian Spruce] One of the most beautiful and valued spruces for landscape planting. More useful than most as a screen where space is limited because of narrow form. Needles can brown in windy exposed sites in winter. Can get aphids, budworms, and borers, though these are not usually serious problems.
Tree Picea orientalis [Oriental Spruce] Generally considered a better choice for the landscape than P. abies (Norway Spruce) or P. glauca (White Spruce). Best in cooler climates; does not always tolerate southern heat and humidity well. In order to prevent desiccation and needle browning, protection from harsh winter winds is advisable for plants grown in colder climates.
Tree Picea pungens [Colorado Spruce] One of the most striking of the conifers in color and habit, especially f. glauca. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color (especially prominent in f. glauca) does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
Tree Picea pungens f. glauca [Colorado Blue Spruce] One of the most striking of the conifers in color and habit. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
Shrub/Tree Picea pungens f. glauca 'Baby Blueyes' [Baby Blueyes Colorado Blue Spruce] 'Baby Blueeyes' is a pyramidal, semi-dwarf cultivar with densely set, bluish-gray needles. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows.

Tree Picea pungens f. glauca 'Fastigiata' [Columnar Colorado Blue Spruce] 'Fastigiata' is a striking conifer with its intense blue-colored foliage and columnar habit. Some drought tolerance. Blue spruce must be used with restraint because it does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
Tree Picea pungens f. glauca 'Globosa' [Dwarf Globe Blue Spruce] 'Glauca Globosa' is a compact (3' high), rounded, flat-topped shrub that at maturity is wider than high; the needles are bluish white and more or less radially disposed.
Tree Picea pungens f. glauca 'Hoopsii' [Hoopsii Colorado Blue Spruce] One of the most striking of the conifers in color and habit, 'Hoopsii' is an especially glaucous blue, dense, pyramidal, and good-performing cultivar. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color does not combine well with other plantings in the landscape. Some susceptibility to Cooley Spruce Gall Adelgid…
Tree Picea pungens f. glauca 'Iseli Foxtail' [Iseli Foxtail Colorado Blue Spruce] 'Iseli Foxtail' is dense, upright, and columnar to pyramidal with new branches that resemble bushy fox tails. One of the most striking of the conifers in color and habit. Some drought tolerance. Cost of most glaucous forms is high because they are produced by grafting and then intensively pruned to shape in nursery rows. Must be used with restraint because the strong blue color does not combine well with other plantings in the landscape. Some…
