Description

Botanical classification: Sarcococca hookeriana.

Variety denomination: ‘PMOORE03’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sarcococca hookeriana. The new cultivar will be referred to hereafter by its cultivar name, ‘PMOORE03’. ‘PMOORE03’ is an evergreen shrub grown for use as a landscape plant and ornamental garden plant.

The new cultivar was derived from a controlled breeding program by the Inventor in Longstock, England. The objective of the breeder was to develop a new cultivar of Sarcococca that performs well in a container. The Inventor made a cross in summer of 2004 between Sarcococca hookeriana var. digyny ‘Purple Stems’ (not patented) as the female parent and an unammed proprieary plant of Sarcococca hookeriana var. humilis from the Inventor's breeding program as the male parent. The Inventor selected ‘PMOORE03’ in 2007 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by semi-ripe stem cuttings in Longstock, England in 2007 by the Inventor. Asexual propagation by semi-ripe stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘PMOORE03’ as a unique cultivar of Sarcococca.

    • 1. ‘PMOORE03’ exhibits broad glossy foliage that is persistently dark green in color.
    • 2. ‘PMOORE03’ exhibits a free flowering habit with fragrant flowers that have white stamens and reddish-pink tepals.
    • 3. ‘PMOORE03’ performs well when container grown (typical plants of Sarcococca hookeriana do not thrive when container grown).
    • 4. ‘PMOORE03’ exhibits a moderate growth rate with good growth in a range of light conditions from light shade to full sun (plants of Sarcococca hookeriana typically do not tolerate full sun).

The female parent of ‘PMOORE03’, ‘Purple Stems’, differs from ‘PMOORE03’ in having leaves that are narrower and a paler shade of green in color, in being more difficult to propograte, and in taking longer to produce a quality plant. The male parent of ‘PMOORE03’, a unnamed plant of Sarcococca hookeriana var. humilis, differs from ‘PMOORE03’ in having a more compact plant habit and in having a slower growth habit. ‘PMOORE03’ can be most closely compared to the Sarcococca cultivars ‘Sarsid 2’ (U.S. Plant Pat. No. 19,951) and ‘Sarsid 1’ (U.S. Plant Pat. No. 19,942). ‘Sarsid 2’ differs from ‘PMOORE03’ in having oblanceolate leaves, more vigourous growth habit and a more compact plant habit. ‘Sarsid 1’ differs from ‘PMOORE03’ in having leaves that are narrow, oblanceolate to elliptic in shape, in having a more vigourous growth habit, and a groundcover plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Sarcococca. The photographs were taken of a three year-old plant of ‘PMOORE03’ as grown in an unheated greenhouse in Boskoop, the Netherlands.

The photograph in FIG. 1 provides a side view of a plant of ‘PMOORE03’.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘PMOORE03’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘PMOORE03’.

The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Sarcococca.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three year-old plants of the new cultivar as grown in an unheated greenhouse in 30-cm containers in Boskoop, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
