Cryptomeria - RadicansCryptomeria Radicans are fast growing evergreen trees with dark green, dense foliage. These trees reach a height of 40 50 feet, but their spread is only 8 12 feet so they work well as a tall evergreen in a tighter space and are also used as high hedges. Radicans are hardy in Zones 5 9. They are less susceptible to tip blight than some variations. USDA ZONES: Zone 5, Zone 6, Zone 7, Zone 8, Zone 9
