plant named ‘MonJers’

Abstract

A new and distinct Tsuga cultivar named ‘MonJers’ is disclosed, characterized by distinctive Yellow-Orange winter foliage. Plants have a distinctive upright, pyramidal growth habit. The new cultivar is a Tsuga, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Tsuga canadensis.

Variety denomination: ‘MonJers’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a breeding program under the direction of the inventor, Ron D. Kinney. This new variety, hereinafter referred to as ‘MonJers’, was selected from seedlings resulting from the collection of seed from an unnamed, unpatented Tsuga canadensis. The pollen parent is unknown. The novel seedling was discovered in a commercial nursery in Dayton, Oreg. during December of 2011.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘MonJers’ by semi-hardwood cuttings at the same commercial nursery during November of 2012. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. At least four 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 ‘MonJers’ 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 ‘MonJers’ These characteristics in combination distinguish ‘MonJers’ as a new and distinct Tsuga cultivar:

• • 1. Unique color of foliage: Winter foliage is colored near Yellow-Orange 18A.
  • 2. Distinctive upright, pyramidal and arching growth habit.

COMPARISON TO PARENT VARIETY

‘MonJers’ is similar in most horticultural characteristics to the seed parent variety. Plants of the new cultivar ‘MonJers’ however, produce distinctive foliage colored near Yellow-Orange 18A in the Winter months. Additionally the plant habit of ‘MonJers’ is upright and pyramidal, whereas the parent variety has a plant habit that is compact and flattened.

COMMERCIAL COMPARISON

In addition to the seed parent, ‘MonJers’ can be compared to the commercial variety Tsuga canadensis ‘Emerald King’, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘MonJers’ produce Winter foliage colored near Yellow-Orange 18A, whereas plants of ‘Emerald King’ remain green.

‘MonJers’ can be compared to the commercial variety Tsuga canadensis ‘MonKinn’, U.S. Plant Pat. No. 25,503. The varieties are similar in most horticultural characteristics, however, plants of ‘MonJers’ are upright and pyramidal, whereas plants of ‘MonKinn’ are compact and flattened.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘MonJers’ grown outdoors in Dayton, Oreg. The plant is approximately 2 years old, and is shown in a three gallon container. The plant of ‘MonJers’ is on the left side of the photograph. The plant on the right side is the comparator, ‘MonKinn’.

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.

• Lateral branch shape in cross section: Generally round.
• Lateral branch strength: Flexible.
• Lateral branch color: Near RHS Greyed-Orange 177B.
• Lateral branch texture: Rough with hard, protruding lenticels. Younger branches do not have lenticels, texture is striated.
