plant named ‘Moonraker’

Abstract

A new cultivar of hybrid Phormium named ‘Moonraker’ that is characterized by its foliage that is variegated with bright green margins and creamy yellow-green centers, its slightly arching plant habit, its small leaves, and its compact plant habit.

Description

Botanical classification: Phormium cookianum×Phormium tenax.

Cultivar designation: ‘Moonraker’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant patent application filed for a plant derived from similar parentage in the Inventors' breeding program that is entitled Phormium Plant Named ‘Chocomint’ (U.S. Plant Pat. No. 12/661,426).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phormium named ‘Moonraker’, an interspecific hybrid of Phormium cookianum×Phormium tenax and referred to hereafter by its cultivar name, ‘Moonraker’. The new cultivar is grown for use as a foliage plant for landscape and container use.

The Inventors discovered the new cultivar summer of 2001 as a naturally occurring chimeral mutation of Phormium ‘Yellow Wave’ (not patented) in a container block in their nursery in Tauranga, New Zealand.

Asexual reproduction of the new cultivar was first accomplished by division in autumn of 2001 in Tauranga, New Zealand by one of the Inventors. The characteristics of this cultivar have been determined to be 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 ‘Moonraker’ as a new and unique cultivar of Phormium.

• • 1. ‘Moonraker’ exhibits foliage that is variegated with bright green margins and creamy yellow-green centers.
  • 2. ‘Moonraker’ exhibits a slightly arching plant habit.
  • 3. ‘Moonraker’ exhibits leaves that are small in size.
  • 4. ‘Moonraker’ exhibits a compact plant habit; reaching 40 to 60 cm in height.

‘Moonraker’ can be compared to the parent plant, ‘Yellow Wave’. ‘Yellow Wave’ is similar to ‘Moonraker’ in having foliage with variegation that is yellow, green, and cream in color. ‘Yellow Wave” differs from ‘Moonraker’ in that the green coloration of the foliage is darker and less green-yellow, in having leaves that are larger in width and length, and in having a less compact plant habit. The closest comparison cultivar is ‘Cream Delight’ (not patented), which is similar in having leaves with green and creamy yellow variegation. The foliage of ‘Cream Delight’ differs from ‘Moonraker’ in that the green coloration is darker and less green-yellow and the creamy colored centers are less green. ‘Cream Delight’ also differs from ‘Moonraker’ in having an arching form typical of Phormium cookianum type Phormium that arches from the base rather being upright and then arching as observed with ‘Moonraker’. ‘Chocomint’, also a mutation of ‘Yellow Wave’, differs from ‘Moonraker’ in having variegated foliage with purple brown centers and green margins.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Phormium. The photographs in FIG. 1 and FIG. 2 were taken of a two year-old plant of ‘Moonraker’ as grown outdoors in a 3-liter container in Auckland, New Zealand.

FIG. 1 provides a side view of ‘Moonraker’ and

FIG. 2 provides a close up view of the foliage of ‘Moonraker’. The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Phormium.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of two year-old plants of the new cultivar as grown outdoors in 3-liter containers in Auckland, New Zealand. The plants were grown under average day temperatures of 20° to 27° C. and average night temperatures of 12° to 20° C. 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
