plant named ‘Screen Play’

Abstract

A new cultivar of Ilex plant named ‘Screen Play’, that is characterized by its well-branched, dense, upright plant habit with suitablity for use as a hedge or privacy screen, its vigourous growth habit with plants growing an average of 1.5 m per year in Georgia when young, its large leaves that emerge light green tinged with bronze in color and maturing to a deep green color, its leaves that are glossy and spineless with very finely serrated margins, its berries that ripen to a deep red color in early fall and persist on the plant through the winter, its cold tolerance; remaining evergreen in U.S.D.A Zone 7, and its ease of pollination by ambient pollen when grown in Georgia.

Description

Botanical classification: Ilex integra×latifolia.

Cultivar designation: ‘Screen Play’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ilex integra×latifolia and will be referred to hereafter by its cultivar name, ‘Screen Play’. ‘Screen Play’ represents a new spine-free (consumer friendly) evergreen holly which displays attractive red fruit all winter and is used as a landscape specimen or hedge.

The Inventor discovered the new cultivar, ‘Screen Play’ in 1994 as a naturally occurring branch mutation of an unnamed and unpatented plant of Ilex integra×latifolia from the Inventor's breeding program that was growing in a trial bed in Saitama City, Japan. The new cultivar was discovered on a plant that was among numerous Ilex integra×latifolia seedings that originated from the Inventor's breeding program in 1987.

Asexual propagation of the new cultivar was first accomplished by the Inventor using semi-soft wood cuttings in Saitama City, Japan in 1994. Subsequent asexual propagation by semi-soft wood cuttings from 2004 to 2009 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 ‘Screen Play’ as a new and distinct cultivar of Ilex.

• • 1. ‘Screen Play’ exhibits a well-branched, dense, and upright plant habit and is suitable for use as a hedge or privacy screen.
  • 2. ‘Screen Play’ exhibits a vigourous growth habit with plants growing an average of 1.5 m per year in Georgia when young.
  • 3. ‘Screen Play’ exhibits large leaves that emerge light green tinged with bronze in color and mature to a deep green color.
  • 4. ‘Screen Play’ exhibits leaves that are glossy and spineless with very finely serrated margins.
  • 5. ‘Screen Play’ exhibits berries that ripen to a deep red color in early fall and persist on the plant through the winter.
  • 6. ‘Screen Play’ exhibits cold tolerance; remaining evergreen in U.S.D.A Zone 7.
  • 7. ‘Screen Play’ is readily pollinated by ambient pollen in Georgia.

The parent of ‘Screen Play’, differs from ‘Screen Play’ in having leaves that are smaller in size and lighter in color, and in having a less dense plant habit. ‘Screen Play’ can most be most closely compared to the Ilex hybrid cultivars ‘Emily Bruner’ (not patented) and ‘Nellie Stevens’ (not patented). ‘Emily Bruner’ is similar to ‘Screen Play’ in having a dense, evergreen plant habit and in producing red berries that persist through the winter. ‘Emily Bruner’ differs from ‘Screen Play’ in having a leaves with spiney margins, in having larger more conspicuous flowers, and in having a broader plant habit. ‘Nellie Stevens’ is similar to ‘Screen Play’ in producing red berries that persist though the winter and in having a large plant habit that is suitable for use as a privacy screen. ‘Nellie Stevens’ differs from ‘Screen Play’ in having leaves that are lighter green in color, recurved and have thorns, in having a more rounded plant habit, in having a less vigorous growth habit, and in being known to self-pollinate.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 4 year-old plants of the new cultivar as grown outdoors in 15-gallon containers in Alpharetta, Ga. 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.
