Abstract

A new Osteospermum plant particularly distinguished by having yellow-orange flowers with a purple base and streaks of purple from the base of the petal to the tip, medium-large flowers and compact growth habit, is disclosed.

Description

Genus and species: Osteospermum hybrida.

Variety denomination: ‘SAKOST3586’.

BACKGROUND OF THE NEW PLANT

‘SAKOST3586’ originated from a hybridization of proprietary hybrid Osteospermum breeding lines ‘203149’ and ‘203148’ in Aabyhoej, Denmark. The proprietary female parent, ‘203149’ (unpatented) has a light bronze-yellow flower color with a terracotta-brown color at the flower petal apices. The proprietary male parent, ‘203148’ (unpatented) has a deep rose-pink flower color that darkens toward the flower petal apices.

In spring 2004, the two Osteospermum lines were crossed and seeds were obtained. The seeds were sown and 300 plants were grown in pots for evaluation. Out of 300 F₁lines, plant number 29 was selected for flower color and size.

In spring 2005, plant number 29 was vegetatively propagated by cuttings and evaluated in an open field and a greenhouse in Denmark. Plant No. 29 was given the code number ‘205036’ and the stability of the distinct characteristics of this variety was confirmed.

In spring 2006, plants ‘205036’ were evaluated again in pots and in an open field. The selection was named ‘SAKOST3586’ 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. Yellow-orange flowers with a purple base and streaks of purple from the base of the petal to the tip;
- 2. Medium-large flowers; and
- 3. Compact 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 4 months from transplant date and six months from stick date in six 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.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘SAKOST3586’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants grown approximately four months from transplant date and six months from stick date into 6-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.), 4^thedition.

DESCRIPTION OF THE NEW PLANT

Classification:
- - Family.—Compositae.
  - Botanical.— Osteospermum hybrida.
Parentage:
- - Female parent.—A hybrid proprietary Osteospermum line ‘203149’, having a light bronze-yellow flower color (unpatented).
  - Male parent.—A hybrid proprietary Osteospermum line ‘203148’, having a deep rose flower color (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, Calif., 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.

COMPARISON WITH PARENTAL LINES AND KNOWN CULTIVARS

‘SAKOST3586’ is a distinct variety of Osteospermum owing to its yellow-orange with streaks of purple flower color, medium-large flower size, flowers that stay open under low light conditions and compact growth habit. ‘SAKOST3586’ is distinguished from its parents primarily by its yellow-orange with streaks of purple flower color and medium-large flower size, as described in Table 1 (color references are to The Royal Horticultural Society Colour Chart, 4^thedition):
