USPP30707P3 - Chamaecyparis plant named ‘SMNCLBF’ - Google Patents

Abstract

A new and distinct Chamaecyparis cultivar named ‘SMNCLBF’ is disclosed, characterized by soft foliage with a blue tint. Plants have low maintenance requirements and are upright with branches occurring at strongly acute angles. The new cultivar is a Chamaecyparis, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Chamaecyparis lawsoniana.

Variety denomination: ‘SMNCLBF’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of chance discovery by the inventor, Timothy Wood. This new variety, hereinafter referred to as ‘SMNCLBF’, was selected as a naturally occurring branch mutation from an unnamed, unpatented Chamaecyparis lawsoniana. The novel variety was discovered in a poly-greenhouse in Grand Haven, Mich. during 2006.

After identifying the new variety as a potentially interesting selection, first propagation of ‘SMNCLBF’ 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 ‘SMNCLBF’ 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 ‘SMNCLBF’ These characteristics in combination distinguish ‘SMNCLBF’ as a new and distinct Chamaecyparis cultivar:

• • 1. Foliage with a blue tint.
  • 2. Good container plant, having low maintenance requirements.
  • 3. Soft texture.

PARENT COMPARISON

‘SMNCLBF’ is similar in most horticultural characteristics to the parent, however, plants of ‘SMNCLBF’ differ in the following:

• • 1. New cultivar has a softer texture; parent foliage is more prickly.
  • 2. The new cultivar has foliage with a blue tint not seen on the parent variety.

COMMERCIAL COMPARISON

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

• • 1. Plants of the new cultivar have more of an acute plant apex; comparator is more columnar.
  • 2. New cultivar is more compact; comparator is taller.
  • 3. New cultivar has branches angled upwards; comparator's branches are more outward and sweeping over.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SMNCLBF’ in a 3 gallon container grown in Grand Haven, Mich. in a polyhouse.

Plants in FIG. 1 are approximately 2 years old.

FIG. 2 illustrates a close up view of the foliage.

FIG. 3 illustrates a plant of the new variety at approximately 2 years old grown outdoors in Grand Haven, Mich. and exhibit the characteristic growth, having a more acute plant apex.

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.
