Additional Information

'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 susceptibility to Cooley Spruce Gall Adelgid (Adelges cooleyi).
