Habit and Form
'Compacta' and 'Nana' - These monikers are used as catch-all names for a wide assortment of clonal selections with dwarf, mounded and compact habits. Many of these forms have individual names, but nurseries tend to clump them all together under these headings. Many of these forms were selected and named by Sidney Waxman, professor emeritus at the University of Connecticut.
'Blue Shag' - A Waxman selection, this popular form is a rounded compact plant with bluish-green needles.
'Contorta' - The main trunk and lateral branches of this plant twist and turn, though the plant forms an upright pyramidal small tree.
'Fastigiata' - This narrow columnar form reaches 50' to 70' tall with a much narrower spread (typically 3 times as tall than wide). The blue-green needles are long and soft in texture.
'Glauca' - This is a catch-all term for many forms that bear bluish-green needles.
'Hillside Winter Gold' - A unique full-sized tree, this plant features light green summer needles that turn a striking golden yellow in fall and winter. The contrast with blue-foliaged conifers can be very striking. 'Aurea' may be very similar, though the needles are yellow-green even in summer, with deeper coloring in winter.
'Pendula' - This popular large, pendulous tree exhibits extreme variation in habit and form. The branches twist and droop, exposing the gray bark and displaying the long, blue-green needles very effectively. It can be trained from an early age to achieve a desired effect.
'Sea Urchin' - Considered one of the finer dwarf globular forms, this Waxman cultivar has blue-green needles and is slow-growing.
'UConn' - A unique Waxman selection, this plant is considered one of the finest "intermediate" forms. In time, the plant becomes a dense, rounded pyramidal tree to 20' tall. It is distinctly tree-like, but the small mature size allows it to be used in many landscapes. The needles are a healthy blue-green color.
