plant named ‘TDMTF’

Abstract

A new and distinct Taxodium cultivar named ‘TDMTF’ is disclosed, characterized by an upright habit and feather-like foliage which is closely spaced. Fall foliage color is orange. The new cultivar is a Taxodium, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Taxodium distichum.

Variety denomination: ‘TDMTF’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety was discovered growing as a seedling among a group of crossbred Taxodium distichum trees at a tree farm in Washington, Ga. The inventor made this discovery in the Summer of 2014. The exact seed and pollen parents cannot be identified.

After identifying the new variety as a potentially interesting selection during 2014, the inventor first organized propagation of ‘TDMTF’ by softwood cuttings at the same commercial nursery during 2014. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Multiple 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 ‘TDMTF’ 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 ‘TDMTF’. These characteristics in combination distinguish ‘TDMTF’ as a new and distinct Taxodium cultivar:

• • 1. Tight, dense habit with feather-like needles closely spaced
  • 2. Orange color in fall
  • 3. Upright, fastigiate growth
  • 4. Dark green foliage

COMPARISON TO PARENT VARIETY

The exact parent varieties cannot be identified.

COMMERCIAL COMPARISON

Taxodium ‘TDMTF’ can be compared to the commercial variety Taxodium distichum ‘Sofine’, U.S. Plant Pat. No. 13,431 Plants are similar in most horticultural characteristics, however, plants of the new variety differ in the following:

• • 1. ‘TDMTF’ is more upright in growth habit and structure than this comparator.
  • 2. ‘TDMTF’ forms finer, denser foliage.
  • 3. The new variety produces a different orange Fall foliage color.
  • 4. The new variety grows slightly slower than this comparator.

Taxodium ‘TDMTF’ can be compared to the commercial variety Taxodium distichum ‘Nelson’, U.S. Plant Pat. No. 12,502. Plants are similar in most horticultural characteristics, however, plants of the new variety differ in the following:

• • 1. ‘TDMTF’ is more upright in growth habit and structure than this comparator.
  • 2. ‘TDMTF’ forms finer, denser foliage.
  • 3. The new variety produces a different orange Fall foliage color.
  • 4. The new variety grows slightly slower than this comparator.

Taxodium ‘TDMTF’ can be compared to the commercial variety Taxodium distichum ‘Peve Minaret’ (unpatented). Plants are similar in most horticultural characteristics, however, plants of the new variety differ in the following:

• • 1. ‘TDMTF’ grows larger than this comparator, which grows into a small tree with a very enlarged trunk.
  • 2. ‘TDMTF’ grows faster than this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical trees of ‘TDMTF’ grown outdoors in Washington, Ga. The trees are approximately 3 years old, shown growing in the ground.

FIG. 2 illustrates a close up of typical foliage of the new variety.

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.
