plant named ‘JAN W3M’

Abstract

A new cultivar of Fargesia plant named ‘JAN W3M’ that is characterized by its short plant height and a compact plant habit, its leaves that are small in size and dark green in color, and its moderate vigor.

Description

Botanical classification: Fargesia hybrid.

Variety denomination: ‘JAN W3M’.

CROSS REFERENCE TO A RELATED APPLICATIONS

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Fergesia Plant Named ‘JAN W3M’ (U.S. Plant patent application Ser. No. 17/009,600). This application is also related to a European plant breeders' rights application filed on Jul. 31, 2017, application No. 2017/1896. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Fargesia of hybrid origin will be referred to hereafter by its cultivar name, ‘JAN W3M’. ‘JAN W3M’ is a new cultivar of bamboo shrub grown for use as a landscape plant.

‘JAN W3M’ was selected as a single unique plant by the Inventor in a trial field in Edewecht, Germany in 2014 (with numerous seedlings evaluated from 2008 to 2014). The trial field had been planted with seeds from an open pollinated plant of an unnamed and unpatented plant of Fargesia murieliae times Fargesia nitida from the Inventor's breeding program. The exact male parent is unknown as the seeds were set after open pollination.

Asexual propagation of the new cultivar was first accomplished by the inventor using division in 2014 in Edewecht, Germany. Asexual propagation by division has been determined that the characteristics of ‘JAN W3M’ are stable and 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 ‘JAN W3M’ as a unique cultivar of Fargesia.

• 1. ‘JAN W3M’ exhibits a short plant height and a compact plant habit.
• 2. ‘JAN W3M’ exhibits leaves that are small in size.
• 3. ‘JAN W3M’ exhibits leaves that are dark green in color.
• 4. ‘JAN W3M’ exhibits moderate vigor.

The female plant of ‘JAN W3M’ differs from ‘JAN W3M’ in having a taller plant height (3.5 m), leaves that are larger in size and leaves that are lighter green in color. Typical plant of Fragesia murieliae x Fragesia nitida differs from ‘JAN W3M’ in having a much taller plant height ‘JAN W3M’ can be most closely compared to the cultivars ‘Jan 108’ (not patented), ‘Bimbo’ (not patented), and ‘JAN W2M’. ‘Jan 108’ differs from ‘JAN W3M’ in having a taller plant height, more vigorous growth habit, and leaves that are larger in size and lighter green in color. ‘Bimbo’ differs from ‘JAN W3M’ in having a wider spreading plant habit, leaves that are larger in size and lighter green in color, and in not responding as well to pruning. ‘JAN W2M’ differs from ‘JAN W3M’ in having a less compact plant habit with a larger plant height and width.
