USPP32580P2 - Metasequoia tree named ‘Soul Fire’ - Google Patents

Abstract

A new and distinct cultivar of Metasequoia tree named ‘Soul Fire’ is disclosed, characterized by interesting foliage colors. Spring foliage is light green and bronze, creating an overall gold appearance. Summer foliage is bright lime green and resists Summer burn. Fall foliage is orange. Internodes are shorter than typical for Metasequoia glyptostroboides with gold foliage. The new cultivar is a Metasequoia, suitable for various landscape purposes.

Description

Latin name of the genus and species: Metasequoia glyptostroboides.

Variety denomination: ‘Soul Fire’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of chance discovery by the inventor. This new variety, hereinafter referred to as ‘Soul Fire’, was selected as single seedling among a planting of commercial trees of unpatented, unnamed Metasequoia glyptostroboides. The new variety was found and selected at a commercial nursery in Malvern, Pa. during Spring of 2015.

After identifying the new variety as a potentially interesting selection, first propagation of ‘Soul Fire’ occurred by grafting semi-softwood tip cuttings onto standard rootstock in 2015. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Three generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Soul Fire’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Soul Fire’ These characteristics in combination distinguish ‘Soul Fire’ as a new and distinct Metasequoia cultivar:

• • 1. Light green and bronze Spring foliage creating a gold overall appearance.
  • 2. Bright lime green foliage in Summer.
  • 3. Orange Fall foliage color.
  • 4. Shorter internodes than other gold foliage forms.
  • 5. No Summer burn to foliage.

COMPARISON TO PARENT VARIETIES

The exact parent varieties are unknown.

COMMERCIAL COMPARISON

‘Soul Fire’ can be compared to the commercial variety Metasequoia glyptostroboides ‘Golden Oji’ (U.S. Plant Pat. No. 9,346) also known as ‘Ogon’. The varieties are similar in most horticultural characteristics, however, trees of ‘Soul Fire’ differ in the following:

• • 1. The new variety has a more compact habit with shorter growth nodes than this comparator.
  • 2. The new variety has brighter and more consistent gold coloring than this comparator.
  • 3. Foliage of the new variety does not burn in the Summer, while foliage of this comparator does burn in the Summer.

‘Soul Fire’ can be compared to the commercial variety Metasequoia glyptostroboides ‘Amberglow’, unpatented. The varieties are similar in most horticultural characteristics, however, trees of ‘Soul Fire’ differ in the following:

• • 1. The new variety has a more compact habit with shorter growth nodes than this comparator.
  • 2. The new variety has brighter and more gold coloring than this comparator.
  • 3. Foliage of the new variety does not burn in the Summer, while foliage of this comparator does burn in the Summer.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical tree of ‘Soul Fire’ grown outdoors in Malvern, Pa. at approximately 4 years of age, during Summer.

FIG. 2 illustrates a close up of the emerging Spring foliage color.

The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
