Abstract

A new and distinct variety of Japanese Snowbell tree named ‘SJMTF’ substantially as herein shown, illustrated and described, characterized particularly as to novelty by its columnar growth habit; dominant central leader, smaller, darker leaves; and its prolific blooms. These genetic traits are unique to my new variety and can be consistently reproduced by asexual propagation.

Description

Latin name of genus and species: Styrax japonicus.
Varietal denomination: Japanese Snowbell tree which I have named ‘SJMTF’.
CROSS REFERENCE TO RELATED APPLICATIONS
Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Japanese Snowbell tree (Styrax japonicus). The variety is designated by the cultivar name ‘SJMTF’.
Discovery
The new Styrax japonicus ‘SJMTF’ variety is the result of a selection made by the inventor, Dwayne Moon, from a tree which was crossed within the species (a male Styrax japonicus named MTF101 and a female Styrax japonicus named MTF201; not patented) at a farm in Madison, Ga. In 2014, the inventor began to take grafts from the mature parent tree and planted them in production fields in Washington, Ga. where evaluation of this tree continues.
Propagation
‘SJMTF’ was asexually propagated by the method of grafting at my direction in the summer of 2014 at a farm in Washington, Ga. This propagation from grafting on Styrax japonicus understock and resulting progeny has proven the characteristics of my new variety to be genetically stable. Furthermore, these observations have confirmed that ‘SJMTF’ represents a new and improved variety of Japanese Snowbell tree as particularly evidenced by the columnar growth habit; dominant central leader; smaller, darker leaves; and its prolific white blooms. These genetic traits are unique to ‘SJMTF’ and can be consistently reproduced by asexual propagation.
Uniqueness
The characteristics of ‘SJMTF’ distinguish it from other typical seedling Japanese Snowbell trees and the known cultivars. At the time this tree was selected, I observed ‘SJMTF’ Japanese Snowbell tree as a two inch caliper tree exhibiting a columnar growth habit; dominant central leader, smaller, darker leaves like (RHS 147A) in summer; and prolific white blooms from May to June. These traits make ‘SJMTF’ significantly different from the species which is rounded to broad-rounded. The traits of ‘SJMTF’ also make it uniquely different from other cultivars such as ‘Evening Shade’ (U.S. Plant Pat. No. 24,168P2) which has foliage that emerges dark purple, ‘Angyo Dwarf’ (patent unknown) which has a dwarf habit; ‘Carillon’, (patent unknown) ‘Pendula’, (patent unknown) and ‘Fragrant Fountains’ (U.S. Plant Pat. No. 19,664) which all have weeping forms; ‘Pink Chimes’ (patent unknown), and ‘Rosea’ (patent unknown) which have pink flowers; ‘Issai’ (patent unknown) which is a faster grower; ‘Emerald Meadow’ (patent unknown) and ‘Snowcone’ (patent unknown) which are pyramidal in habit; ‘Emerald Pagoda’ (patent unknown) which has larger leaves, and larger, heavier flowers; ‘Crystal’ (patent unknown) which has an upright fastigiate habit with flowers which have purple pedicels; ‘Kusan’ (patent unknown) which has a compact, globe-shaped form; and ‘Snow Charm’ (patent unknown) and ‘Snowfall’ (patent unknown) which both have rounded habits.
Use
‘SJMTF’ was observed for a period of several years and is believed to be particularly useful as a specimen tree in commercial and residential areas, and is worthy of extensive landscape use from golf courses, commercial sites, and parks. ‘SJMTF’ will also benefit growers who will profit from the desired look of a high quality flowering tree due to its columnar growth habit, very dark foliage, along with abundant white bell-shaped blooms.
SUMMARY OF THE INVENTION Background
Seedling Japanese Snowbell is a small, low-branched tree which develops a rounded to broad-rounded crown with a wide-spreading, horizontal branching pattern. Mature native Japanese Snowbell trees are typically 20 to 30 feet in height with a spread of 15 to 25 feet. Japanese Snowbell tree is native to China, Korea, and Japan being introduced in 1862. It is noted for its pendulous clusters of bell-shaped, mildly fragrant, waxy white flowers that bloom in May-June. Flowers give way to greenish-brown, olive-shaped drupes that often persist into late autumn. Elliptic-ovate, glossy, medium to deep green leaves. Fall color is usually insignificant, however leaves may sometimes turn yellow to red. Japanese Snowbell tree variety ‘SJMTF’ is an improvement over the species in that it is asexually reproduced with a columnar growth habit with a dominant central leader; smaller, darker leaves like (RHS 147A) in summer; and prolific white blooms from May to June. The ultimate height and width of a fully grown, mature ‘SJMTF’ is not known. The new Japanese Snowbell tree ‘SJMTF’ variety is expected to perform as well as the species varieties.

 DETAILED DESCRIPTION OF THE INVENTION Botanical Description of the Plant
The following is a detailed description of ‘SJMTF’ Japanese Snowbell tree with color terminology in accordance with The Royal Horticulture Society (R.H.S.) Colour Chart (2001) except where the context indicates a term having its ordinary dictionary meaning.
‘SJMTF’ has not been observed under all growing conditions, and variations may occur as a result of different growing conditions. All progeny of ‘SJMTF’, insofar as have been observed by the inventor, have remained genetically stable in all characteristics described hereinafter. Other than as set out hereinafter, as of this time, no other characteristics have been observed by the inventor that are different from common Japanese Snowbell trees.
