Description

Genus/species: Carpinus caroliniana.

Varietal denomination: ‘JN Select A’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carpinus caroliniana and will be referred to hereafter by its cultivar name, ‘JN Select A’. ‘JN Select A’ represents a new cultivar of American hornbeam, ironwood, or musclewood, a deciduous tree grown for landscape use.

The Inventor discovered the new cultivar in May of 2003 as a chance seedling that was growing in a block of seedlings planted in 1996 from seed derived from open pollination of unnamed and unpatented plants of Carpinus caroliniana in Menomonee Falls, Wis. Both the female and male parent are unknown.

Asexual propagation of the new cultivar was first accomplished in 2004 by side-veneer grafting onto seedling Carpinus caroliniana understock by the Inventor in Menomonee Falls, Wis. Asexual propagation by side-veneer grafting and cleft grafting 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 Carpinus. These attributes in combination distinguish ‘JN Select A’ as unique and distinct cultivar of Carpinus.

    • 1. ‘JN Select A’ exhibits foliage that consistently turns deep orange-red in color in the fall in Southern Wisconsin.
    • 2. ‘JN Select A’ exhibits a vigorous growth rate.
    • 3. ‘JN Select A’ exhibits good cold hardiness in Southern Wisconsin.

Typical plants of Carpinus caroliniana differ from ‘JN Select A’ in being less winter hardy, in having a less vigorous growth habit, and in having fall color that is less red in color. ‘JN Select A’ can be most closely compared to the Carpinus caroliniana cultivar ‘JFS-KW6’ (not patented)'. ‘JFS-KW6’ is similar to ‘JN Select A’ in having orange-red fall color in Southern Wisconsin. ‘JFS-KW6’ differs from ‘JN Select A’ in having a much less consistent orange-red fall foliage color and in showing a high degree of winter damage (twig die-back) in severe winters in Southern Wisconsin.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographs were taken of 10 year-old plants of ‘JN Select A’ as grown in a trial garden in Menomonee Falls, Wis.

The photograph in FIG. 1 provides a side view of the plant habit and fall foliage of ‘JN Select A’.

The photograph in FIG. 2 provides a close-up view of the fruit clusters and bracts of ‘JN Select A’.

The photograph in FIG. 3 provides a close-up view of the fall foliage of ‘JN Select A’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the colors of the new Carpinus.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 3 year-old plants as grown outdoors in 3-gallon containers and 10 year-old plants as grown in a trial garden in Menomonee Falls, Wis. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
