Penstemon plant named ‘Pheni Reeda’

Abstract

A new Penstemon plant particularly distinguished by brilliant red and white flowers, medium size inflorescences, early flowering, medium-green foliage with narrow lanceolate leaves, medium vigorous growth, and an upright plant habit that is well-branched with steady and sturdy stems is disclosed.

Description

Genus and species: Penstemon hartwegii Benth.

Variety denomination: ‘Pheni Reeda’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Penstemon, botanically known as Penstemon hartwegii, and hereinafter referred to by the cultivar name ‘Pheni Reeda’. The new cultivar originated from a hybridization made in 2002 in Gilroy, Calif. The female parent is a proprietary Penstemon plant designated ‘106-1’ (unpatented) having dark pink flowers, and the male parent is a proprietary Penstemon plant designated ‘109-2’ (unpatented) having red 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. Brilliant red and white flowers;
  • 2. Medium sized inflorescences;
  • 3. Early flowering;
  • 4. Medium green foliage with narrow lanceolate leaves;
  • 5. Medium vigorous growth; and
  • 6. An upright and well-branched plant habit with steady and sturdy 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. 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 Reeda’. 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 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).

• Growth:
  • • Form.—Herbaceous perennial; suffrutescent; tolerates only slight frost; usually cultivated as an annual plant.

    • Time to initiate and develop roots.—21 days in the spring.
    • Root description.—Somewhat fleshy at the base, mainly fibrous, and self-branching.
• Leaves:
  • • Arrangement.—Opposite and decussate.
    • Shape.—Lanceolate.
    • Apex.—Acute.
    • Base.—Sessile.
