Abstract

A new Penstemon plant particularly distinguished by large red-purple flowers with white throats, large inflorescences, early flowering, medium to grass-green foliage with lanceolate leaves, vigorous growth, and an upright, robust and relatively compact plant habit with steady stems is disclosed.

Description

Genus and species: Penstemon hartwegii Benth.
Variety denomination: ‘Pheni Magna’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of Penstemon, botanically known as Penstemon hartweggi, and hereinafter referred to by the cultivar name ‘Pheni Magna’. The new cultivar originated from a hybridization made in 2002 in Gilroy, Calif. The female parent is a proprietary Penstemon plant designated ‘110-1’ (unpatented), having red flowers and the male parent is a proprietary Penstemon plant designated ‘112-1’ (unpatented), having lavender flowers. The seeds produced by the hybridization were sown in November 2002, and the resulting seedlings were selected in May 2003. A single plant selection was chosen for further evaluation and for asexual propagation in the summer of 2003.
The new cultivar was created in 2002 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. over a three-year period. The plant has also been trialed at Gilroy, Calif., and Hillscheid, Germany. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this cultivar were applied for in Europe on Oct. 14, 2005 and in Canada on Mar. 29, 2005.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Hillscheid, Germany.
    • 1. Large red-purple flowers with white throats;
    • 2. Large inflorescences;
    • 3. Early flowering;
    • 4. Medium to grass-green foliage with lanceolate leaves;
    • 5. Vigorous growth; and
    • 6. An upright, robust and relatively compact and steady plant habit with steady stems.
DESCRIPTION OF PHOTOGRAPHS
This new Penstemon plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant in full color; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of whole plants about 3 months old, grown in a field in Gilroy, Calif. in mid July 2005.
FIG. 1 shows the overall plant habit, including blooms, buds, mature foliage, and plant habit.
FIG. 2 shows a close-up of the mature inflorescences.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Pheni Magna’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on nine to eleven-week-old plants grown in Hillscheid, Germany in 2005. Rooted cuttings were planted into 12-cm plastic pots placed in a greenhouse. The plants were not pinched, so they mostly developed into single-stem plant habits. Most observations were made after nine to ten weeks at the beginning of flowering. Color readings were taken under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).
DETAILED BOTANICAL DESCRIPTION OF THE NEW PLANT
  • Classification:
      • Family.—Scrophulariaceae.
      • Botanical name.—Penstemon hartwegii Benth.
  • Parentage:
      • Female parent.—‘110-1’ a proprietary red-flowered Penstemon plant (unpatented).
      • Male parent.—‘112-1’ a proprietary lavender-flowered Penstemon plant (unpatented).
  • Growth:
      • Form.—Herbaceous perennial; suffrutescent; tolerates only slight frost and because of its short cultivation time, it is usually cultivated as an annual plant.
      • Habit.—Un-pinched plants develop one flowering main stem and only occasionally, weaker secondary branches at the base; for commercial purposes, the young plants are usually pinched so that 5-10 stems of equal size will develop.
      • Height.—71 cm for a 9-week-old single-stem plant (as measured from the soil to the tip, including the inflorescence).
      • Width.—Up to 20 cm.
      • Time to produce a finished flowering plant.—About 10-11 weeks for as a single-stem plant in a 5-inch pot; 13 weeks for a branched plant planted outdoors.
      • Outdoors plant performance.—Use in garden beds or in container planting.
      • Time to initiate and develop roots.—21 days.
      • Root description.—Somewhat fleshy at the base, mainly fibrous, and self-branching.
  • Leaves:
      • Arrangement.—Opposite and decussate.
      • Shape.—Lanceolate.
      • Apex.—Acute to acuminate.
      • Base.—Sessile.

      • Mature (fully expanded).—Length: 14.0 cm. Width: 4.0 cm. Color: General: Grass green. Upper surface: RHS 143A. Lower surface: Between RHS 138A and RHS 138B. Texture: Smooth, glabrous, and slightly glossy.
      • Venation.—Type: Pinnate; with the midrib of the lower side protruding; other veins are hardly visible. Color (midrib, lower side): RHS 145B (pale green).
  • Stems:
      • Length.—48 cm as measured from the base, excluding the inflorescence.
      • Diameter.—0.7 cm as measured at the midpoint.
      • Internode length.—3-4 cm.
      • Color.—RHS 143D (light green).
      • Texture.—Appears smooth, with sparse pubescence.
