  • Patent number: PP5457
    Abstract: A new and distinct blue spruce tree variety originating as a chance seedling growing among a cultivated group of grafted Picea pungens Moerheimi planted in a cultivated nursery area at Silverton, Oreg. The new variety is unique in its upright, semi-dwarf growth habit with early apical dominance; its naturally pyramidal configuration; the delayed spring growth of its dormant buds; and its dense foliage of a sky-grey color. These characteristics make it well suited for a wide range of landscape uses, as well as for live, potted Christmas trees.
