USPP25304P3 - Distylium plant named ‘PIIDIST-III’ - Google Patents

Abstract

A new and distinct cultivar of Distylium plant named ‘PIIDIST-III’, characterized by its compact, rounded to spreading growth habit, bronze-purple new growth, dark bluish green mature foliage, and reddish maroon flowers.

Description

Genus and species of plant claimed: Distylium sp. hybrid.

Variety denomination: ‘PIIDIST-III’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Distylium plant, botanically known as Distylium sp. hybrid, a member of the Hamamelidaceae, and hereinafter referred to by the cultivar name ‘PIIDIST-III’. ‘PIIDIST-III’ is grown primarily as an ornamental for landscape use and for use as a potted plant.

‘PIIDIST-III’ originated in 2008 as an open-pollinated seedling from bulk seed collected from several unnamed and unpatented selections of Distylium sp. hybrids as part of a breeding program in Watkinsville, Ga. Due to the bulk seed collection, the exact parents are unknown. ‘PIIDIST-III’ originated and was selected by the inventor in a cultivated environment in Watkinsville, Ga. from the progeny of this open-pollination by continued evaluation for growth habit and foliage characteristics.

Asexual reproduction of ‘PIIDIST-III’ by stem cuttings in Watkinsville, Ga. since 2010 has shown that all the unique features of ‘PIIDIST-III’, 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 ‘PIIDIST-III’ 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 ‘PIIDIST-III’. These characteristics in combination distinguish ‘PIIDIST-III’ as a new and distinct cultivar: 1. Compact, rounded to spreading growth habit; 2. Bronze-purple new growth; 3. Dark bluish green mature foliage; and 4. Reddish maroon flowers.

Plants of the new Distylium ‘PIIDIST-III’ can be compared to plants of the cultivar ‘PIIDIST-II’ (U.S. Plant Pat. No. 24,409), but differ in growth habit and foliage color. ‘PIIDIST-III’ has a compact, rounded to spreading growth habit and bronze-purple new growth that matures to bluish green, whereas ‘PIIDIST-III’ has a compact, spreading growth habit and maroon-purple new growth that matures to darker blue-green.
