Description

Genus and species: Osteospermum hybrida.

Variety denomination: ‘SAKOST8367’.

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 ‘SAKOST8367’. ‘SAKOST8367’ originated from a hybridization in Marslev, Denmark of the female commercial Osteospermum variety ‘SAKOST8202’, also commercially known as CAPE DAISY™ ‘Softly Pink’ (U.S. application Ser. No. 13/134,031) having light pink flowers (young flowers have a pinkish-white flower color) with light gray disc florets, and the male commercial Osteospermum variety ‘SAKOST8201’, also commercially known as CAPE DAISY™ ‘Purple Illumination’ (U.S. application Ser. No. 13/068,016) having white with purple flowers and violet-blue disc florets.

In May 2008, the two Osteospermum lines ‘SAKOST8202’ and ‘SAKOST8201’ were crossed and seeds were obtained. The seeds were sown and plants were grown in pots for evaluation. In February 2009, a line was selected which had unique medium sized rose-pink flowers with violet-blue disc florets. This line also has a very compact and very well-branching plant growth habit.

In February 2009, the line was vegetatively propagated by cuttings and re-evaluated in an open field and a greenhouse. The line was given the breeder code number ‘209149’ and the stability of the distinct characteristics of this variety was confirmed.

In June 2009, plants from ‘209149’ were evaluated again in pots and in an open field. Line ‘209149’ was subsequently designated ‘SAKOST8367’ 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. Medium sized rose-pink flowers with violet-blue disc florets; and
    • 2. A very compact and very well-branching plant growth 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 twelve months from transplant into 8-inch pots from rooted cuttings in Salinas, Calif. under greenhouse conditions in the fall of 2012. 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 ‘SAKOST8367’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants grown approximately twelve months from transplant into 8-inch pots under greenhouse conditions in Salinas, Calif. in the fall of 2012. 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.—‘SAKOST8367’.
  • Parentage:
      • Female parent.—The commercial Osteospermum variety ‘SAKOST8202’, also commercially known as CAPE DAISY™ ‘Softly Pink’ (U.S. application Ser. No. 13/134,031).
      • Male parent.—The commercial Osteospermum variety ‘SAKOST8201’, also commercially known as CAPE DAISY™ ‘Purple Illumination’ (U.S. application Ser. No. 13/068,016).
  • 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 in the spring, summer and fall in the United States. Vernalization is not required to induce flowering.
