Description

Botanical classification: Prunus persica.

Variety denomination: ‘Grepeptwst’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Prunus persica and will be referred to hereafter by its cultivar name, ‘GREPEPTWST’. ‘GREPEPTWST’ is a new cultivar of peach tree grown as an ornamental landscape plant.

The Inventor discovered the new cultivar as naturally occurring branch mutation of Prunus persica ‘Peppermint Stick’ (not patented) that was growing in a field at his nursery in Winchester, Tenn. in 2010.

Asexual propagation of the new cultivar was first accomplished by budding by the Inventor in Winchester, Tenn. in June of 2010. Asexual propagation by budding 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 ‘GREPEPTWST’ as a unique cultivar of Prunus.

    • 1. ‘GREPEPTWST’ exhibits contorted branches that result in a contorted, pendulous plant habit.
    • 2. ‘GREPEPTWST’ exhibits spring flowers that are double and light pink in color.
    • 3. ‘GREPEPTWST’ exhibits foliage that is contorted (very curly) in aspect.

‘Peppermint Stick’, the female parent of ‘GREPEPTWST’, differs from ‘GREPEPTWST’ in having an upward and oval growth habit and in having foliage that is flat in aspect. ‘GREPEPTWST’ can be most closely compared to the Prunus persica varieties ‘Bonfire’ (not patented) and ‘Corinthian Rose’ (U.S. Plant Pat. No. 11,564). ‘Bonfire’ differs from ‘GREPEPTWST’ in being shorter in height and narrower in width, in having branches that are straight (not contorted), in having foliage that is red in color and in having flowers that are pink to red in color. ‘Corinthian Rose’ is similar to ‘GREPEPTWST’ in having double flowers in spring. ‘Corinthian Rose’ differs from ‘GREPEPTWST’ in having a columnar plant habit, in having foliage that is flat in aspect, and in having flowers that are darker pink in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new cultivar, ‘GREPEPTWST’. The photographs were taken of a four year-old plant of ‘GREPEPTWST’ as grown outdoors in a trial bed in Winchester, Tenn.

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

The photograph in FIG. 2 provides a close-up view of the contorted branches of ‘GREPEPTWST’.

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

The photograph in FIG. 4 provides a close-up view of the flowers of ‘GREPEPTWST’.

The photograph in FIG. 5 provides a close-up view of a fruit of ‘GREPEPTWST’.

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 new Prunus.

DETAILED BOTANICAL DESCRIPTION
