Perovskia plant named `Novaperlac`
Abstract
The new plant resulted as a mutation of a common plant of
Perovskia atriplicifolia (unnamed and non-patented). The mutation
was induced by exposing tissue cultured shoots to gamma irradiation
and was followed by selection. Attractive purple blossoms are
formed in abundance. A dense substantially upright compact growth
habit is displayed. Sturdy branching is exhibited. The plant is
well suited for providing attractive ornamentation in the landscape
and has tended to blossom primarily in July through September.

Claims
I claim:
1. A new and distinct Perovskia atriplicifolia plant having the
following combination of characteristics: (a) exhibits a dense
substantially upright growth habit, (b) exhibits sturdy branching,
(c) displays finely-textured foliage, (d) forms in abundance
attractive purple blossoms, and (e) is well suited for providing
attractive ornamentation in the landscape; substantially as
illustrated and described.
Description
Botanical classification: Perovskia atriplicifolia.
Varietal denomination: cv. Novaperlac.
SUMMARY OF THE INVENTION
Perovskia atriplicifolia is an ornamental herbaceous perennial
plant commonly known as Russian Sage.
The new plant of the present invention was derived by induced
mutagenesis from a plant of the species Perovskia atriplicifolia
(unnamed and non-patented). More specifically, on Oct. 26, 2006
tissue cultured shoots were subjected to gamma irradiation to yield
a diverse population of plants that included many mutations which
differed widely from each other. The irradiated shoots were rooted
during July 2007, were transferred to soil, and were acclimatized
during September 2007. The resulting plants were transferred to
one-gallon containers in the spring of 2008, and were studied in
detail at West Grove, Pa., U.S.A., for the possible presence of a
novel attractive phenotype. A single plant of the present invention
was selected and was preserved in view of its unique combination of
attractive phenotypic characteristics. Had this plant not been
created, identified and preserved it would have been lost to
mankind.
It was found that the new Perovskia plant of the present invention
displays the following combination of characteristics: (a) exhibits
a dense substantially upright growth habit, (b) exhibits sturdy
branching, (c) displays finely-textured foliage, (d) forms in
abundance attractive purple blossoms, and (e) is well suited for
providing attractive ornamentation in the landscape.
During observations to date, the plant has been found to be hardy
in U.S.D.A. Hardiness Zone No. 6. No further definitive hardiness
information has been obtained.
The new cultivar well meets the needs of the horticultural industry
and can be grown to advantage as a perennial garden plant to
provide distinctive ornamentation. For instance, it can be grown in
parks, gardens and residential settings.
Plants of the new cultivar in view of its combination of phenotypic
characteristics can be readily distinguished from other Perovskia
plants of the species, including its parent. More specifically, the
new cultivar is significantly shorter than the parent plant, being
about half the height of the Perovskia atriplicifolia (unnamed and
non-patented) parent plant when grown in West Grove, Pa., U.S.A.
Further, when compared to the `Lisslitt` cultivar (U.S. Plant Pat.
No. 20,845) in a side-by-side comparison at West Grove, Pa.,
U.S.A., the new cultivar was found to exhibit sturdier stems and a
more upright growth habit.
The rooting of terminal cuttings has been used to asexually
propagate the new cultivar at West Grove, Pa., U.S.A. It has been
found that the characteristics of the new cultivar are stable and
are reliably transmitted from one generation to another.
Accordingly, the new cultivar can be asexually reproduced in a
true-to-type manner.
The new cultivar of the present invention has been named
`Novaperlac`, and will be marketed under the LITTLE LACE
Trademark.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the new cultivar in color
as nearly true as it is reasonably possible make the same in color
illustrations of this nature. The plants were approximately one
year of age and were being grown outdoors in full sun during July
2013 on their own roots at West Grove, Pa., U.S.A.
FIG. 1 illustrates specimens of typical mature flowering plants of
the new cultivar at the left. The typical dense upright compact
growth habit is shown. At the right is shown typical plants of
`Lisslitt` cultivar. Such `Lisslitt` plants are shown to display
less sturdy and less upright stems.
FIG. 2 illustrates another view of a typical flowering plant of the
new cultivar.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description while observing
two-year-old plants of the new cultivar that were produced by the
rooting of cuttings. Such plants were being grown in one-gallon
containers under greenhouse conditions at West Grove, Pa., U.S.A.
The chart used in the identification of color is The R.H.S. Colour
Chart (1995 Edition or equivalent) of The Royal Horticultural
Society, London, England. Common color terms are to be accorded
their customary dictionary significance. Botanical classification:
