Abstract

A new Osteospermum plant particularly distinguished by having flowers with a pink ray floret color and blue disc florets, medium flower size, flowers that stay open under low light conditions and mounded cascading plant habit, is disclosed.

Description

Genus and species: Osteospermum hybrida.
Variety denomination: ‘SAKOST3441’.
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 ‘SAKOST3441’. ‘SAKOST3441’ originated from a hybridization of proprietary hybrid Osteospermum breeding lines ‘98071’ and ‘98064’ in Aabyhoej, Denmark. The proprietary female parent, ‘98071’ (unpatented) has a white flower color and a cascading plant habit. The proprietary male parent, ‘98064’ (unpatented) has a dark pink flower color and a compact and semi-cascading plant habit.
In May 2001, the two Osteospermum lines ‘98071’ and ‘98064’ were crossed and seeds were obtained. The seeds were sown and 300 plants were grown in pots for evaluation. Out of 300 F1 lines, plant number 38 which has a pink ray floret color with blue disc florets and a mounded cascading plant habit was selected.
In February 2002, plant number 38 was vegetatively propagated by cuttings and re-evaluated in an open field and a greenhouse. Plant number 38 was given the breeder code number ‘202188’ and the stability of the distinct characteristics of this variety was confirmed.
In spring 2005, plants were evaluated again in pots and in an open field The selection was named ‘SAKOST3441’ and was found to reproduce true to type in successive generations of asexual propagation.
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. Pink ray floret color with blue disc florets
    • 2. Medium flower size;
    • 3. Flowers that stay open under low light conditions; and
    • 4. Mounded, cascading growth 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 four and a half months from transplant date and five and a half months from stick date into 8-inch pots from rooted cuttings in Salinas, Calif. in the spring of 2008.
The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
FIG. 1 shows overall plant habit of the plant grown in a pot.
FIG. 2 shows the mature inflorescence of the plant.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘SAKOST3441’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants grown approximately four and a half months from transplant date and five and a half months from stick date into 8-inch pots under greenhouse conditions in Salinas, Calif. in the spring of 2008. 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.
  • Parentage:
      • Female parent.—A hybrid proprietary Osteospermum line ‘98071’, having a white flower color and a cascading plant habit (unpatented).
      • Male parent.—A hybrid proprietary Osteospermum line ‘98064’, having dark pink flower color and a compact and semi-cascading plant habit (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 150–200 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°–18° C. for good root growth. When plants reach 7.5–10 cm in height they are pinched back to 5–6 leaves to promote branching. Spring and summer daytime high temperatures in Salinas, California, where the data was collected, range from 16°–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.
