Scaevola plant named ‘Bomy Pinka’

Abstract

A Scaevola plant particularly distinguished by light pink flowers in a tight cluster, a mid-season and continuous flowering response, medium green foliage with fleshy leaves, a vigorous growth habit and a medium-sized plant habit, an initially spreading to decumbent to trailing plant habit, a rounded, bushy and well-branched plant habit, and good heat tolerance, is disclosed.

Description

Genus and species: Scaevola aemula.

Variety denomination: ‘Bomy Pinka’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Scaevola, botanically known as Scaevola aemula and hereinafter referred to by the cultivar name ‘Bomy Pinka’. The new cultivar originated from a hybridization made in July 2003 in Gilroy, Calif. The female parent was ‘1012’, a proprietary violet-flowered Scaevola plant (unpatented), while the male parent was ‘1035’, a proprietary violet-blue-flowered Scaevola plant (unpatented).

The new cultivar was created in July 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 one and one-half-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.

Plants Breeder's Rights for this cultivar have been applied for in Canada on Mar. 29, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Hillscheid, Germany.

• • 1. Light pink flowers in a tight cluster;
  • 2. A mid-season and continuous flowering response;
  • 3. Medium green foliage with fleshy leaves;
  • 4. A vigorous growth habit and a medium-sized plant habit;
  • 5. An initially spreading to decumbent to trailing plant habit;
  • 6. A rounded, bushy and well-branched plant habit; and
  • 7. Good heat tolerance.

DESCRIPTION OF THE PHOTOGRAPHS

This new Scaevola plant is illustrated by the accompanying photographs which show overall plant habit including inflorescences, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photos are of a 26-week-old plant grown in a greenhouse in an early September trial setting.

FIG. 2 shows a closer view of a portion of the plant.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Bomy Pinka’. the data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. Rooted cuttings wee planted into 12-cm plastic pots in early March and pinched once. In late May, the plants were transplanted to outdoor hanging baskets that were situated under light rain protection. The plant history was taken on 11-week-old plants grown in a greenhouse and on 26-week-old plants grown outdoors in Hillscheid, Germany in Spring to late-Summer 2005. Observations were made in mid-May 2005, when the plants began flowering, and then in early September 2005, when the plants were in full-flower and reached their full size. 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).
