Abstract

A Portulaca plant particularly distinguished by having pink flowers, a flower blooming period from spring to fall, and a semi-mounding, upright, and vigorous plant growth habit, is disclosed.

Description

Genus and species: Portulaca oleracea.

Variety denomination: ‘SAKPOR003’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Portulaca plant, botanically known as Portulaca oleracea, and referred to by the variety name ‘SAKPOR003’. ‘SAKPOR003’ originated from a hybridization in Kakegawa, Japan in 2006 between the female Portulaca line ‘Mo04-24B-V2’, an unpatented proprietary Portulaca breeding line having a gold flower color and a bush growth habit, and the male Portulaca line ‘BB03-36A-V4’, an unpatented proprietary Portulaca breeding line with a rose flower color and bushy growth habit.

In August 2006, the female parent line ‘Mo04-24B-V2’ and male parent line ‘BB03-36A-V4’ were crossed and F₁seeds were obtained. In May 2007, the F₁seed was sown in the greenhouse, cultivated and plant lines were produced with red, scarlet, pink, and white flowers having a bushy plant habit. The plants were evaluated and plant line ‘K2008-172’ was selected for its pink flower color, flower blooming period from spring to fall, and vigorous plant growth habit.

In May 2008, ‘K2008-172’ was vegetatively propagated, cultivated, and evaluated. In August 2008, ‘K2008-172’ was confirmed to be fixed and stable. In May 2009, May 2010, and May 2011, ‘K2008-172’ was vegetatively propagated to reconfirm its stability. ‘K2008-172’ was subsequently named ‘SAKPOR003’ and its unique characteristics were 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. Pink flower color;
- 2. Flower blooming period from spring to fall; and
- 3. A semi-mounding, upright, and vigorous plant growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

This Portulaca 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 twelve-month-old plant grown 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 ‘SAKPOR003’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on twelve-month-old plants grown 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.), 4^thedition (2001).

Classification:

Growth:
- - Time to produce a rooted cutting.—About 2 weeks.
  - Environmental conditions for plant growth.—The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated in five to six weeks. The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N Grow (1 solution:9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24° C.
