USPP19256P2 - Calibrachoa plant named ‘Cal Paicoras’ - Google Patents

Abstract

A new Calibrachoa plant particularly distinguished by coral flowers with light pink margins and darker red mid-veins, early and continuous flowering, narrow, dark green foliage, good vigor, semi-upright to later prostrate or trailing plant habit, is disclosed.

Description

Genus and species: Calibrachoa sp.

Variety denomination: ‘Cal Paicoras’.

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 Paicoras’. The new cultivar originated from a hybridization made in July 2003 in Gilroy, Calif. The female parent was the red-purple with cream margins-flowered Calibrachoa plant ‘Cal Rostar’ (U.S. Plant Pat. No. 16,772), while the male parent was the scarlet-flowered Calibracho plant ‘Cal Scaredtwo’ (U.S. Plant Pat. No. 16,771). The seeds produced by the hybridization were sown in January 2004 in Gilroy, Calif. A single plant selection was chosen for further evaluation and for asexual propagation in April 2004 in Gilroy, Calif.

The new cultivar was created in 2003 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. Andijk, The Netherlands and Hillscheid, Germany over a three-year period. The plant has also been trialed at Gilroy, Calif. Andijk, The Netherlands 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 the European Union on Feb. 26, 2007 and in Switzerland on Oct. 30, 2006.

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. Coral flowers with light pink margins and dark red mid-veins;
  • 2. Narrow, dark green foliage;
  • 3. Good vigor;
  • 4. Semi-upright to later prostrate to trailing plant habit; and
  • 5. An early and 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 whole plants about 20-weeks old, grown in a greenhouse in Hillscheid, Germany. The potted plant photograph was taken in May. The basket plants were moved outside to grow in the summer and the photograph was taken in August.

FIG. 1 shows a close-up of the mature flowers.

FIG. 2 shows the overall plant habit, including blooms, buds, and foliage.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Cal Paircoras’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 16-week old plants grown in 6-inch pots in a greenhouse in the spring season in a trial setting. The plants had one plant growth regulator treatment and one terminal pinch after cuttings were transplanted to the 6-inch pots. 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). Texture description data was viewed with a dissecting microscope.

COMPARISON WITH PARENTAL/COMMERCIAL CULTIVARS

‘Cal Paicoras’ differs from the female parent ‘Cal Rostar’ (U.S. Plant Pat. No. 16,772) by having larger flowers that are more coral in color than the rose colored flowers of ‘Cal Rostar’. ‘Cal Paicoras’ shorter, green leaves than ‘Cal Rostar’. Additionally, ‘Cal Paicoras’ is more floriferous and has a taller plant height than ‘Cal Rostar’.

‘Cal Paicoras’ differs from the male parent ‘Cal Scaredtwo’ (U.S. Plant Pat. No. 16,771) by having smaller leaves and a more prostrate growth habit than ‘Cal Scaredtwo’. Additionally, ‘Cal Paicoras’ is earlier to flower than ‘Cal Scaredtwo’.

‘Cal Paicoras’ differs from the commercial comparison variety ‘Balcabhopi’ (U.S. Plant Pat. No. 18,795) in that ‘Cal Paicoras’ has coral-colored flowers with light-pink margins and dark red mid-veins, while ‘Balcabhopi’ had dark-ink-colored flowers with greyed-purple venation.
