'Emerald Sentinel' - This is a new pyramidal, columnar for growing 20' tall and only 8' wide. The foliage is dark green and the color is held well in winter. It is a fruiting female variety.
'Glauca' - This name serves as an umbrella for many clones with bluish needles, often fading in summer. Most grow 15'-20' tall with a pyramidal form. 'Manhattan Blue' is similar, growing to 12' tall.
'Grey Owl' - A low spreading form to 18" tall with 3' to 6' spread, this plant bears fine, feathery foliage of a silver-blue color. It is a compact, spreading grower only growing 6' tall but much wider in time. It is an abundant fruiting clone.
'Hillspire' - This male clone assumes a symmetical pyramidal habit with healthy green foliage. The foliage color is maintained in winter.
'Pendula' (also listed as f. pendula) - Many clones carry this name, and most have spreading limbs with pendulous branchlets. They can grow to 40' tall and feature abundant blue fleshy cones.
