A distinct cultivar of Juniper plant named `Taylor's Blue`, characterized by its very low-growing, procumbent plant habit; unique silvery-blue leaf color; relative ease of rooting; and tolerance to low temperatures.

BACKGROUND OF THE INVENTION
 The present invention relates to a new and distinct cultivar of Juniper
 plant, botanically known as Juniperus horizontalis, and hereinafter
 referred to by the cultivar name Taylor's Blue.
 The new Juniper is a naturally-occurring whole plant mutation of an
 unidentified selection of Juniperus horizontalis (not patented). The new
 Juniper was discovered and selected by the Inventor in 1984, within a
 population of plants of the unidentified Juniperus horizontalis selection
 grown in a cultivated area in Lewis and Clark County, Montana. The new
 Juniper was selected on the basis of its unique silvery-blue foliage color
 and procumbent growth habit.
 Plants of the new Juniper are lower-growing than plants of the parent
 selection, an unidentified selection of Juniperus horizontalis. In
 addition, foliage color of plants of the parent selection is typically
 green whereas foliage color of plants of the new Juniper is silvery-blue.
 Asexual reproduction of the new cultivar by cuttings taken at Boulder,
 Colo., and Irvine, Calif., has shown that the unique features of this new
 Juniper are stable and reproduced true to type in successive generations.
 SUMMARY OF THE INVENTION
 Plants of the cultivar Taylor's Blue have not been observed under all
 possible environmental conditions. The phenotype may vary somewhat with
 variations in environment such as temperature, light intensity, daylength,
 and fertility level without, however, any variance in genotype.
 The following traits have been repeatedly observed and are determined to be
 the unique characteristics of `Taylor's Blue`. These characteristics in
 combination distinguish `Taylor's Blue` as a new and distinct cultivar:
 1. Very low-growing, procumbent plant habit.
 2. Unique silvery-blue leaf color.
 3. Relatively easy to root.
 4. Tolerant to low temperatures.

DETAILED BOTANICAL DESCRIPTION
 In the following description, color references are made to The Royal
 Horicultural Society Colour Chart except where general terms of ordinary
 dictionary significance are used.
 Plants used for the description were one-year old and were grown in
 one-gallon containers under outdoor production conditions during the
 spring and early summer in Irvine, Calif.
