USPP36786P2 - Distylium plant named ‘CG-46-22’ - Google Patents

Abstract

A new and distinct cultivar of Distylium plant named ‘CG-46-22’, characterized by its compact, layered (branches uniformly stacked), mounding habit; distinctive greyed-purple new foliage color and lanceolate, olive-green mature foliage. Plants have a low temperature tolerance within USDA Zones 6-9 and are tolerant of high temperatures to at least 95° F. The new variety is a Distylium, typically for ornamental garden use.

Description

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

Variety denomination: ‘CG-46-22’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Distylium plant, botanically known as Distylium hybrid, a member of the Hamamelidaceae family, and hereinafter referred to by the cultivar name ‘CG-46-22’.

‘CG-46-22’ originated as an open-pollinated seedling from seed collected from Distylium hybrid ‘PIIDIST-V’, U.S. Plant Pat. No. 27,631, growing in Watkinsville, Georgia. ‘CG-46-22’ is a Distylium spp. hybrid (Distylium myricoides x D. racemosum) selected in 2022 by the inventors in a cultivated environment in Watkinsville, GA.

Asexual reproduction of ‘CG-46-22’ was first performed by stem cuttings in 2022 has shown that all the unique features of ‘CG-46-22’, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation. First propagation took place at research nursery in Watkinsville, Georgia.

SUMMARY OF THE INVENTION

‘CG-46-22’ has 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 observed and represent the characteristics of the new cultivar. In combination, these characteristics distinguish ‘CG-46-22’ from all other varieties in commerce known to the inventor:

• 1. Compact, layered (branches uniformly stacked), and mounding growth habit.
• 2. Greyed-Purple new growth.
• 3. Lanceolate, olive-green foliage on mature growth.
• 4. Low temperature tolerance within USDA Zones 6-9. High temperature tolerance to at least 95° F.

PARENTAL COMPARISON

Plants of the new cultivar ‘CG-46-22’ are comparable to the seed parent in most horticultural characteristics. However, the new variety ‘CG-46-22’ differs in the following:

• 1. New growth of ‘CG-46-22’ is Greyed-Purple, whereas the new growth of the seed parent is a lighter red.
• 2. Mature growth of ‘CG-46-22’ olive-green, whereas the mature growth of the seed parent is blue-green.
• 3. Plants of ‘CG-46-22’ are overall larger than plants of the seed parent.

COMMERCIAL COMPARISONS

Plants of the new cultivar ‘CG-46-22’ can be compared to the commercial cultivar ‘PIIDIST-IV’, U.S. Plant Pat. No. 25,984, in most horticultural characteristics. However, the new variety ‘CG-46-22’ differs in the following:

• 1. Plants of ‘CG-46-22’ have a compact, layered, mounding habit, whereas plants of this comparator have an upright habit.
• 2. New growth of ‘CG-46-22’ is Greyed-Purple, whereas the new growth of this comparator is red.
• 3. Mature growth of ‘CG-46-22’ olive-green, whereas the mature growth of this comparator is dark green.

Plants of the new cultivar ‘CG-46-22’ can be compared to the commercial cultivar ‘PIIDIST III’, U.S. Plant Pat. No. 25,304, in most horticultural characteristics. However, the new variety ‘CG-46-22’ differs in the following:

• 1. Plants of ‘CG-46-22’ have shown more cold-hardiness than plants of this comparator.
• 2. New growth of ‘CG-46-22’ is Greyed-Purple, whereas the new growth of this comparator is bronze-purple.
• 3. Mature growth of ‘CG-46-22’ olive-green, whereas the mature growth of this comparator is dark bluish-green.
