Calibrachoa plant named ‘Cal Depyel’

Abstract

A new Calibrachoa plant particularly distinguished by medium-sized, deep-yellow flowers, an early to moderately-early and continuous flowering response, grass-green to deep-green, glossy foliage with lanceolate leaves, moderately vigorous growth, a medium-sized and spreading to prostrate plant habit, with strong branches, is disclosed.

Description

Genus and species: Calibrachoa sp.

Variety denomination: ‘Cal Depyel’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Calibrachoa, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Cal Depyel’. The new cultivar originated from a hybridization made in July 2002 in Gilroy, Calif. The female parent was the proprietary deep-yellow flowered Calibrachoa plant ‘471-1’ (unpatented), while the male parent was the proprietary Calibrachoa plant ‘465-1’ (unpatented) having deep yellow flowers. The seeds produced by the hybridization were sown in January 2003 in Gilroy, Calif. A single plant selection was chosen for further evaluation and for asexual propagation in Summer 2004 in Gilroy, Calif.

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 two-year period. ‘Cal Depyel’ has not been observed under all possible environmental conditions. 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 Canada on Mar. 31, 2005, in Switzerland on Sep. 16, 2005 and with the European Union on Sep. 28, 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. Medium-sized, deep-yellow flowers;
  • 2. Green-green to deep-green, glossy foliage with lanceolate leaves;
  • 3. Moderately vigorous growth with strong branches;
  • 4. A medium-sized and spreading to prostate or trailing plant habit; and
  • 5. An early to moderately early and a continuous flowering response.

DESCRIPTION OF PHOTOGRAPHS

This new Calibrachoa plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a whole plant about 11-weeks old, grown in a greenhouse in Hillscheid, Germany, in May of 2005.

FIG. 1 shows the overall plant habit, including blooms, buds and foliage.

FIG. 2 shows a close-up of the mature inflorescences.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Cal Depyel’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 6-week old unpinched plants which were planted as rooted cuttings in 12-cm pots in July 2005, and then grown in a greenhouse. Observations were made when the plants were in full flower in August 2005. Color readings were taken under natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Cal Depyel’ differs from the female parent ‘471-1’ (unpatented) by having smaller leaves, a more prostrate plant habit and an earlier flowering response than ‘471-1’.

‘Cal Depyel’ differs from the male parent ‘465-1’ (unpatented) by having larger flowers than ‘465-1’. In addition, ‘Cal Depyel’ develops more basal branches, and at a later stage, develops more flowers in the center of the plant than ‘465-1’.

‘Cal Depyel’ differs from the commercial cultivar ‘Cal Yel’ (U.S. Plant Pat. No. 14,464) by having larger, deep and more uniform yellow flowers than ‘Cal Yel’ (RHS 9A for ‘Cal Depyel’ compared to RHS 10A for ‘Cal Yel’). In addition, ‘Cal Depyel’ has brighter green foliage and fewer but stronger branches with longer internodes than ‘Cal Yel’.
