Description

Genus and species: Osteospermum hybrida.

Variety denomination: ‘SAKOST8340’.

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 ‘SAKOST8340’. ‘SAKOST8340’ originated from a hybridization in May-June 2008 in Marslev, Denmark of the proprietary female Osteospermum variety ‘206156’ (unpatented) and the commercial male Osteospermum variety ‘SAKOST8201’ (U.S. Publication No. 2012/0278960). The goal of this breeding program was to create a plant having white and purple ray florets and white-grey disc florets.

In May-June 2008, the two Osteospermum lines ‘206156’ and ‘SAKOST8201’ were crossed and seeds were obtained. The seeds were sown and plants were grown in pots for evaluation. In winter 2008-2009, a line was selected.

In February 2009, the line was first vegetatively propagated by cuttings and re-evaluated in an open field and a greenhouse in May 2009. In June 2009 and autumn 2010, the line was selected for further trialing and the stability of the distinct characteristics of this variety was confirmed.

The line was subsequently designated ‘SAKOST8340’ and was found to reproduce true to type in successive generations of asexual propagation via 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. Compact plant with good branching;
    • 2. Flowers composed of ray florets having a purple base and a white and purple stripe towards the tips with white-grey disc florets; and
    • 3. Flowers open pale colored and flower color increases in intensity over the next 2 to 3 flowering days.

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 were taken in January 2013 and are of a plant grown seven months from transplant into 6-inch pots from rooted cuttings in Salinas, Calif. under greenhouse conditions. 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 a close-up of the mature inflorescence of the plant.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKOST8340’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected in January 2013 on 20-week-old plants grown approximately seven months from transplant into 6-inch pots under greenhouse conditions in Salinas, Calif. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4th edition. Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University.

  • Classification:
      • Family.—Compositae.
      • Botanical.—Osteospermum hybrida.
      • Common.—Osteospermum, South African Daisy.
      • Designation.—‘SAKOST8340’.
  • Parentage:
      • Female parent.—The proprietary Osteospermum variety ‘206156’ (unpatented).
      • Male parent.—The commercial male Osteospermum variety ‘SAKOST8201’ (U.S. Publication No. (2012/0278960).
  • 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 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 16 cm diameter pot. Flowering season is all year in the United States. Vernalization is not required to induce flowering.
