USPP35121P2 - Phormium plant named ‘PKFJTB18’ - Google Patents

Abstract

A new cultivar of Phormium plant named ‘PKFJTB18’ that is characterized by a moderate overall size, young leaves that are variegated with a grey-brown center band, pink stripes on both sides of the center band and red-orange margins, young leaves that are upright and mature leaves that are outwardly arching, a basal clump that is yellow-green in color and a good multiplication rate by division.

Description

Botanical classification: Phormium tenax.

Variety denomination: ‘PKFJTB18’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phormium plant botanically known as Phormium tenax and hereinafter referred to by the cultivar name ‘PKFJTB18’.

‘PKFJTB18’ was discovered as a naturally occurring whole plant mutation within a commercial crop of Phormium tenax ‘Sundowner’ (not patented) in 2009. The new cultivar was discovered as a single plant in a cultivated area of Whenuapai, Auckland, New Zealand. The new cultivar was discovered in a commercial plant nursery container field.

Asexual reproduction of the new cultivar ‘PKFJTB18’ first occurred by division in 2010 in Whenuapai, Auckland, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Phormium cultivar ‘PKFJTB18’. These traits in combination distinguish ‘PKFJTB18’ as a new and distinct cultivar apart from other existing varieties of Phormium known by the inventor.

• • 1. Phormium ‘PKFJTB18’ exhibits a moderate overall size.
  • 2. Phormium ‘PKFJTB18’ exhibits young leaves that are variegated with a grey-brown center band, pink stripes on both sides of the center band and red-orange margins.
  • 3. Phormium ‘PKFJTB18’ exhibits young leaves that are upright and mature leaves that are outwardly arching.
  • 4. Phormium ‘PKFJTB18’ exhibits a basal clump that is yellow-green in color.
  • 5. Phormium ‘PKFJTB18’ exhibits a good multiplication rate by division.

The closest comparison cultivars are Phormium ‘Evening Glow’ (not patented) and Phormium ‘Rainbow Sunrise’ (not patented). ‘PKFJTB18’ is distinguishable from ‘Evening Glow’ by the following characteristics:

• • 1. Phormium ‘PKFJTB18’ exhibits a moderate overall size. In comparison, ‘Evening Glow’ has a larger overall size than the overall size of ‘PKFJTB18’.
  • 2. Phormium ‘PKFJTB18’ exhibits young leaves that are variegated with a grey-brown center band, pink stripes on both sides of the center band and red-orange margins. In comparison, the leaves of ‘Evening Glow’ are red-pink with darker red-purple margins.
  • 3. Phormium ‘PKFJTB18’ exhibits young leaves that are upright and mature leaves that are outwardly arching. In comparison, both young and mature leaves of ‘Evening Glow’ are outwardly arching.
  • 4. Phormium ‘PKFJTB18’ exhibits leaves that are wider than the leaves of ‘Evening Glow’. The leaves of ‘PKFJTB18’ average 45 mm. in width while the leaves of ‘Evening Glow’ average 35 mm. in width.

‘PKFJTB18’ is distinguishable from ‘Rainbow Sunrise’ by the following characteristics:

• • 1. Phormium ‘PKFJTB18’ exhibits a moderate overall size. In comparison, ‘Rainbow Sunrise’ has a larger overall size than the overall size of ‘PKFJTB18’.
  • 2. Phormium ‘PKFJTB18’ exhibits young leaves that are variegated with a grey-brown center band, pink stripes on both sides of the center band and red-orange margins. In comparison, the leaves of ‘Rainbow Sunrise’ are rose-pink and fade to pale yellow with bronze-green margins.
  • 3. Phormium ‘PKFJTB18’ exhibits young leaves that are upright and mature leaves that are outwardly arching. In comparison, both young and mature leaves of ‘Rainbow Sunrise’ are upright.
  • 4. Phormium ‘PKFJTB18’ exhibits leaves that are wider than the leaves of ‘Rainbow Sunrise’. The leaves of ‘PKFJTB18’ average 45 mm. in width while the leaves of ‘Rainbow Sunrise’ average 35 mm. in width.

‘PKFJTB18’ is distinguishable from the parent plant Phormium ‘Sundowner’ by the following characteristics:

• • 1. Phormium ‘PKFJTB18’ exhibits a moderate overall size. In comparison, ‘Sundowner’ has a larger overall size than the overall size of ‘PKFJTB18’.
  • 2. Phormium ‘PKFJTB18’ exhibits young leaves that are variegated with a grey-brown center band, pink stripes on both sides of the center band and red-orange margins. In comparison, the leaves of ‘Sundowner’ are bronze-green with rose-pink margins fading to cream color.
  • 3. Phormium ‘PKFJTB18’ exhibits young leaves that are upright and mature leaves that are outwardly arching. In comparison, both young and mature leaves of ‘Sundowner’ are upright.
  • 4. Phormium ‘PKFJTB18’ exhibits leaves that are narrower than the leaves of ‘Sundowner’. The leaves of ‘PKFJTB18’ average 45 mm. in width while the leaves of ‘Sundowner’ average 75 mm. in width.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Phormium ‘PKFJTB18’. The photograph shows an overall view of a 3 year old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance, it is as accurate as possible by conventional photographic techniques. 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 Phormium.

BOTANICAL DESCRIPTION OF THE PLANT
