plant named ‘Novapename’

Abstract

The new Penstemon plant was created by a controlled plant breeding program followed by selection, open pollination, and further selection. The growth habit is upright with strong basal branching and excellent vigor. Attractive large light- lavender flowers with a white throat on sturdy stems are formed. There is no vernalization requirement for flowering. An upright mounding growth habit is displayed. The plant readily roots from stem cuttings and is well suited for providing attractive ornamentation.

Description

Botanical/commercial classification: Penstemon hybrida/Penstemon Plant.

Varietal denomination: cv. Novapename.

SUMMARY OF THE INVENTION

Penstemon plants, sometimes known as Beard Tongue, are herbaceous perennials which provide colorful flowers during the summer.

The new Penstemon plant of the present invention was created and discovered at West Grove, Pa., U.S.A. The female parent (e.g., seed parent) was an unnamed, non-patented breeder seedling resulting from the cross of Penstemon mexicali ‘Pike's Peak Purple’ (non-patented)×Penstemon hartwegii ‘Giganteus’ (non-patented). This breeder seedling, which served as the female parent, was selected from the progeny of the cross in view of its large blooms, increased branching, and extended length of bloom time. This female parent next underwent open pollination in a controlled plant nursery setting tended by man. Seed from this open pollination was collected during August 2011 and was grown in tissue culture before being acclimated to soil in October 2011. Seedlings were observed from the possible presence of promising novel photypes during the summer of 2012 when the plant of the present invention was selected on the basis of large colorful blossoms, well-branched growth habit, sturdy stems, and prolonged bloom time. Had this new plant not been selected and preserved it would have been lost to mankind.

The parentage of the new cultivar can be summarized as follows:
(Penstemon mexicali ‘Pike's Peak Purple’×Penstemon hartwegii ‘Giganteus’)×Open Pollination.

It was found that the new Penstemon plant displays the following combination of characteristics:

• • (a) displays an upright growth habit with strong basal branching and excellent vigor,
  • (b) is lacking a vernalization requirement for flowering,
  • (c) abundantly forms attractive large light-lavender flowers with a white throat on sturdy stems, and
  • (d) is well suited for providing attractive ornamentation.

During observations to date, the plant has been found to be hardy at U.S.D.A. Hardiness Zone No. 6. Trimming of the plant promotes further flowering.

The new cultivar well meets the needs of the horticultural industry and can be grown to advantage as a perennial garden plant to provide colorful ornamentation. The plant performs well when grown along borders or sidewalks as well as in containers.

Plants of the new cultivar can be readily distinguished from other Penstemon cultivars. More specifically, when compared to its ‘Pike's Peak Purple’ ancestor, the new cultivar displays lighter (more lilac) colored flowers that are considerably larger in size, and when compared to its ‘Giganteus’ ancestor displays large lighter lavender flowers unlike the bright red flowers of ‘Giganteus’.

Also, when compared to the ‘Blueberry Taffy’ cultivar (U.S. Plant Pat. No. 22,568), the new cultivar displays larger light-lavender flowers with a white throat unlike the purple-blue flowers having a dark maroon ring at the base of the lobes and white throat of the ‘Blueberry Taffy’ cultivar. Also, the new cultivar displays considerably more branching than the ‘Blueberry Taffy’ cultivar

The new cultivar readily roots from stem cuttings.

The rooting of vegetative 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 ‘Novapename’, and will be marketed under the AMETHYST QUARTZ Trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate typical flowering plants of 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 two years of age and were being grown outdoors on their own roots during June 2014 at West Grove, Pa., U.S.A. The plants had been asexually reproduced by the rooting of vegetative cuttings.

FIG. 1 illustrates the attractive upright growth habit of a flowering plant of the new cultivar.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description while observing one-year-old plants of the new cultivar that were produced by the rooting of vegetative cuttings. Such plants were being grown in containers on their own roots at West Grove, Pa., U.S.A. The chart used in the identification of color is The R.H.S. Colour Chart (1995 Edition) of The Royal Horticultural Society, London, England. Common color terms are to be accorded their customary dictionary significance.
