Description

Genus and species: Osteospermum hybrida.

Variety denomination: ‘SAKOST8433’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Osteospermum, botanically known as Osteospermum hybrida, and hereinafter referred to by the variety name ‘SAKOST8433’. ‘SAKOST8433’ originated from a hybridization of Osteospermum proprietary breeding line ‘206065’ and the commercial hybrid Osteospermum line ‘SAKOST8077’ (U.S. Plant Pat. No. 22,628) in Marslev, Denmark. The female parent, ‘206065’ has a dark yellow to bronze flower color, brown center and a fairly compact plant habit. The male parent, ‘SAKOST8077’, has a red to bronze flower color with a brown center and a semi-erect plant habit.

In June 2007, the two Osteospermum lines ‘206065’ and ‘SAKOST8077’ were crossed and seeds were obtained. The seeds were sown and 108 plants were grown in pots for evaluation. Out of 108 F1 lines, one plant, named plant number 40, was selected which had reddish-purple to orange flowers, a large flower size and a compact plant habit.

In February 2008, plant number 40 was vegetatively propagated by cuttings and re-evaluated in an open field and a greenhouse. Plant number 40 was given the breeder code number ‘OST208040’ and the stability of the distinct characteristics of this variety was confirmed.

In May 2008, plants from ‘OST208040’ were evaluated again in pots and in an open field. ‘OST208040’ was renamed ‘SAKOST8433’ and was found to reproduce true to type in successive generations of asexual propagation from vegetative cuttings.

SUMMARY

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

    • 1. Reddish purple to orange flower color;
    • 2. Large flower size; and
    • 3. Compact plant habit.

DESCRIPTION OF THE 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 four months from transplant (five months from sticking) into 4-inch pots from rooted cuttings in Salinas, Calif. under greenhouse conditions in the spring of 2011. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows the overall plant habit of the plant grown in a pot.

FIG. 2 shows the mature inflorescence of the plant.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKOST8433’. The data which define these characteristics were collected from asexual reproductions from vegetative cuttings carried out in Salinas, Calif. Data was collected on plants grown approximately four months from transplant (five months from sticking) into 4-inch pots under greenhouse conditions in Salinas, Calif. in the winter of 2011. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4th edition.

  • Classification:
      • Family.—Compositae.
      • Botanical.—Osteospermum hybrida.
      • Common.—Osteospermum, Cape Daisy, South African Daisy.
      • Designation.—‘SAKOST8433’.
  • Parentage:
      • Female parent.—The proprietary Osteospermum line ‘206065’ (unpatented).
      • Male parent.—The Osteospermum line ‘SAKOST8077’ (U.S. Plant Pat. No. 22,628).
  • 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, a liquid rooting concentrate for 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 4-inch diameter pot. Flowering season is all year in the United States when grown in a greenhouse, otherwise, it is spring to fall. Vernalization is not required to induce flowering.
