Description

Genus and species: Osteospermum hybrida.

Variety denomination: ‘SAKOST8076’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Osteospermum, botanically known as Osteospermum hybrida, and hereinafter referred to by the cultivar name ‘SAKOST8076’. ‘SAKOST8076’ originated from a hybridization of proprietary hybrid Osteospermum commercial lines ‘Akkalav’ and ‘Sun-sation Blue’ in Aabyhoej, Denmark. The female parent, ‘Akkalav’ has a lavender with blue eye flower color and a compact plant habit. The male parent, ‘Sun-sation Blue’, has a purple flower color and a mounding plant habit.

In May 2004, the two Osteospermum lines were crossed and seeds were obtained. The seeds were sown and 200 F1 plants were grown in pots for evaluation. A single plant having medium-sized blue-colored flowers and a compact and mounding plant habit was selected for further evaluation and propagation.

In February 2005, the single plant was vegetatively propagated by cuttings and re-evaluated in an open field and a greenhouse, and assigned the breeder code number ‘205114’.

In spring 2005, ‘205114’ plants were evaluated again in pots and in an open field. ‘205114’ was named ‘SAKOST8076’ and was found to reproduce true to type in successive generations of asexual propagation through vegetative cuttings.

SUMMARY OF THE INVENTION

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

    • 1. Antique blue or violet ray floret color;
    • 2. Medium flower size; and
    • 3. Compact and mounding plant habit.

DESCRIPTION OF PHOTOGRAPHS

This new Osteospermum plant is illustrated by the accompanying photographs which show the plant's overall plant habit including form, foliage, and flowers. The photographs are of a plant grown six months from transplant date and ten months from stick date into 8-inch pots from rooted cuttings in Salinas, Calif. in the spring of 2009 through the winter of 2010. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 2 shows the mature inflorescence of the plant.

 DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘SAKOST8076’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants grown approximately six months from transplant date and ten months from stick date into 8-inch pots under greenhouse conditions in Salinas, Calif. in the spring of 2009 through the winter of 2010. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4th edition.

DESCRIPTION OF THE NEW PLANT

  • Classification:
      • Family.—Compositae.
      • Botanical.—Osteospermum hybrida.
      • Common.—Osteospermum, Cape Daisy, South African Daisy.
      • Designation.—‘SAKOST8076’.
  • Parentage:
      • Female parent.—A hybrid proprietary Osteospermum line ‘Akkalav’ (unpatented).
      • Male parent.—A hybrid proprietary Osteospermum line ‘Sun-sation Blue’ (unpatented).
  • Growth:
      • Time to produce a rooted cutting.—Cuttings will colonize a 2.5 cm diameter by 2.5 cm tall greenhouse tray cell with peat-based plant media in approximately four weeks. Cuttings are dipped in a normal dilution (1:9) of DIP 'N GROW root inducing solution in water. The trays are misted hourly during rooting.
      • Environmental conditions for plant growth.—Rooted cuttings are transplanted to pots with a 16 cm diameter, one plant per pot. Peat-based growing media is used. The pots are watered using a 150 ppm to 200 ppm fertilizer solution using 18-8-18 fertilizer. The soil is allowed to dry between watering. During the first few weeks after transplanting, the plants should have evening temperatures around 15° C. to 18° C. for good root growth. When plants reach 7.5 cm to 10 cm in height, they are pinched back to 5 to 6 leaves to promote branching. Spring and summer daytime high temperatures in Salinas, Calif., where the data was collected, range from 16° C. to 25° C.
      • Time to bloom from propagation.—Approximately four weeks when rooted vegetative cuttings are transferred to a 5-inch diameter pot. Flowering season is all year in the United States. Vernalization is not required to induce flowering.
