USPP21287P2 - Illicium plant named ‘Pink Frost’ - Google Patents

Abstract

A new and distinct cultivar of Illicium plant named ‘Pink Frost’, characterized by its compact, rounded growth habit, medium green foliage with cream-white marginal variegation, pink-red petioles, red flowers, and pink to red foliage in winter.

Description

Genus and species of plant claimed: Illicium floridanum.

Variety denomination: ‘Pink Frost’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Illicium plant, botanically known as Illicium floridanum, and hereinafter referred to by the cultivar name ‘Pink Frost’.

The new Illicium plant originated as a branch mutation on a container-grown Illicium floridanum in a cultivated environment at Fayetteville, Ga. in 2003.

Asexual reproduction of the new cultivar by stem cuttings at Watkinsville, Ga. since 2005 has shown that all the unique features of this new Illicium, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘Pink Frost’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Pink Frost’. These characteristics in combination distinguish ‘Pink Frost’ as a new and distinct cultivar: 1. Compact, rounded growth habit; 2. Medium green foliage with cream-white marginal variegation; 3. Pink-red petioles; 4. Red flowers; and 5. Pink to red foliage in winter.

Plants of the new Illicium ‘Pink Frost’ differ from plants of the parent, Illicium floridanum, primarily in foliage color, as plants of ‘Pink Frost’ have medium green foliage with cream-white marginal variegation, whereas plants of the parent have medium green foliage with no variegation.

Plants of the new Illicium can be compared to plants of Illicium floridanum forma variegatum Gaddy (U.S. Plant Pat. No. 16,269). However, in side-by-side comparisons conducted at Watkinsville, Ga., plants of the new Illicium differed from plants of Illicium floridanum forma variegatum Gaddy in the following characteristics: 1. Plants of the new Illicium had regular, elliptical-shaped, medium green foliage with uniform cream-white marginal variegation, whereas plants of Illicium floridanum forma variegatum Gaddy commonly had distorted, asymmetrical foliage with curved apices that was gray-green in color with irregular white to yellow marginal variegation; 2. Plants of the new Illicium had red flowers, whereas plants of Illicium floridanum forma variegatum Gaddy had white to pale pink flowers; and 3. Plants of the new Illicium rooted faster, produced saleable plants quicker, grew better, and were more cold hardy than plants of Illicium floridanum forma variegatum Gaddy.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the flower and foliage characteristics and the overall habit of the new Illicium, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. 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 Illicium.
