plant named ‘SMNCLMG’

Abstract

A new and distinct variety of Chamaecyparis plant named ‘SMNCLMG’ is disclosed, characterized by a fresh green foliage color which is well maintained. Plants are compact and full with a teardrop shape. Plants are low maintenance. The new cultivar is a Chamaecyparis, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Chamaecyparis lawsoniana.

Variety denomination: ‘SMNCLMG’.

BACKGROUND OF THE INVENTION

The new Hydrangea cultivar is a product of a planned breeding program conducted by the inventor, at a commercial nursery in Grand Haven, Mich. The objective of the breeding program was to produce new Chamaecyparis varieties with new low maintenance growth, good foliage texture and interesting foliage colors. The open-pollination resulting in this new variety was made during July of 2006. Parent varieties cannot be identified. ‘SMNCLMG’ was selected during 2010 at the same commercial nursery in Grand Haven, Mich.

After identifying the new variety as a potentially interesting selection, first propagation of ‘SMNCLMG’ occurred by softwood cuttings at a commercial nursery in Grand Haven, Mich. in 2010. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Five 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 ‘SMNCLMG’ 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 ‘SMNCLMG’. These characteristics in combination distinguish ‘SMNCLMG’ as a new and distinct Chamaecyparis cultivar:

• • 1. Compact and very full plant habit.
  • 2. Fresh green color is well maintained.
  • 3. Teardrop plant shape.

COMMERCIAL COMPARISON

‘SMNCLMG’ can be compared to the commercial variety Chamaecyparis lawsoniana ‘Minima Aurea’, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘SMNCLMG’ differ in the following ways:

• • 1. Plants of the new variety are narrower, having a more teardrop shape; plants of this comparator are wider and more columnar.
  • 2. Branches of the new variety grow both upwards and outward; branches of this comparator grow mostly upwards.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical foliage of ‘SMNCLMG’ grown outdoors in Grand Haven, Mich. at about 8 years of age.

FIG. 2 illustrates a plant of the new variety at approximately 2 years old, also grown outdoors in Grand Haven, Mich.

The photographs were 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.

DETAILED BOTANICAL DESCRIPTION
