plant named ‘PIIIP-I’

Abstract

A new cultivar of Illicium plant named, ‘PIIIP-I’, that is characterized by its evergreen, compact, mounding growth habit, its foliage that is yellow-green in color in the summer, its foliage that is yellow in color in the winter, and its flowers that are yellow in color.

Description

Botanical classification: Illicium parviflorum.

Cultivar designation: ‘PIIIP-I’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Illicium parviflorum, botanically known as Illicium ‘PIIIP-I’ and will be referred to hereafter by its cultivar name, ‘PIIIP-I’. ‘PIIIP-I’ represents a new evergreen shrub grown for landscape use.

The new cultivar of Illicium arose from an ongoing breeding program conducted by the Inventors in Watkinsville, Ga. ‘PIIIP-I’ originated as a seedling that arose from seed planted from the open pollination of Illicium parviflorum ‘Florida Sunshine’ (not patented) in 2009. ‘PIIIP-I’ was selected as a single unique plant in 2011 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by one of the Inventors using semi-hardwood cuttings in Watkinsville, Ga. in 2011. Asexual propagation by semi-hardwood cuttings has determined that the characteristics of this cultivar 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 ‘PIIIP-I’ as a new and distinct cultivar of Illicium.

• • 1. ‘PIIIP-I’ exhibits an evergreen, compact, mounding growth habit.
  • 2. ‘PIIIP-I’ exhibits foliage that is yellow-green in color in the summer.
  • 3. ‘PIIIP-I’ exhibits foliage that is yellow in color in the winter.
  • 4. ‘PIIIP-I’ exhibits flowers that are yellow in color.

Plants of the new Illicium ‘PIIIP-I’ can be most closely compared to the female parent ‘Florida Sunshine’. ‘PIIIP-I’ is distinguished from its female parent ‘Florida Sunshine’ primarily in growth habit. ‘Florida Sunshine’ has a more open and loser habit and is ultimately a taller plant, whereas ‘PIIIP-I’ has a tight, dense habit and is ultimately smaller in height than ‘Florida Sunshine’.

Plants of the new Illicium ‘PIIIP-I’ can also be compared to typical plants of Illicium parviflorum (not patented), but differs in the following characteristics; ‘PIIIP-I’ has yellow-green foliage in the summer, whereas Illicium parviflorum has olive green foliage. ‘PIIIP-I’ is a plant that needs to be planted in the full shade, whereas Illicium parviflorum performs well not only in the full shade, but also the full sun.

Plants of the new Illicium ‘PIIIP-I’ can also be compared to its sister seedling known as ‘YL-02-09’ (not patented). ‘PIIIP-I’ has a tighter denser habit, whereas ‘YL-02-09’ is more like its female parent having a more open, loser habit in general and becoming much taller than ‘PIIIP-I’. ‘PIIIP-I’ does not scorch as bad in the sun as ‘YL-02-09’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Illicium. The photographs were taken of six year-old plants of ‘PIIIP-I’ as grown in the ground in Watkinsville, Ga.

The photograph in FIG. 1 provides a side-view of the overall plant habit of ‘PIIIP-I’.

The photograph in FIG. 2 provides a close-up view of the flowers and foliage of ‘PIIIP-I’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Illicium.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of six year-old plants of the new cultivar as grown in the ground under shade in Watkinsville, Ga.
