Abstract
A new and distinct Metasequoia cultivar named ‘Urban Spire’ is disclosed, characterized by a distinctive upright, narrow tree form. Branches are held at angles of approximately 45 degrees or less, forming the distinctive narrow shape. The tree is well suited for small properties, street applications or as a specimen in the landscape. The new cultivar is a Metasequoia, suitable for various landscape purposes.
Description
Latin name of the genus and species: Metasequoia glyptostroboides.
Variety denomination: ‘Urban Spire’.
The new cultivar is a product of chance discovery by the inventors, Timothy Sterling and Andrew Schenk. This new variety, hereinafter referred to as ‘Urban Spire’, was selected as single seedling among a commercial planting of numerous seedling trees of unpatented, unnamed Metasequoia glyptostroboides. The novel variety was discovered in a commercial nursery in Malvern, Pa. during August of 2007.
After identifying the new variety as a potentially interesting selection, first propagation of ‘Urban Spire’ occurred by bud wood graft during September of 2012 at a commercial nursery in Malvern, Pa. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Three generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.
The cultivar ‘Urban Spire’ 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 ‘Urban Spire’ These characteristics in combination distinguish ‘Urban Spire’ as a new and distinct Metasequoia cultivar:
-
- 1. Slender, upright growth habit.
- 2. Suitability as a street tree or specimen.
- 3. Suitability for smaller landscape situations.
‘Urban Spire’ is similar in most horticultural characteristics to the parent variety. Trees of the new cultivar ‘Urban Spire’ however, are distinctively more narrow with more acute branching angles.
In addition to the seed parent, ‘Urban Spire’ can be compared to the commercial variety Metasequoia glyptostroboides ‘Sheridan Spire’, unpatented. The varieties are similar in most horticultural characteristics, however, trees of ‘Urban Spire’ differ in the following:
-
- 1. The new variety has a denser habit with shorter growth nodes.
- 2. Branch angle of the new variety is 45 degrees from center, or more acute, ‘Sheridan Spire’ has a broader branch angle.
- 3. Overall habit of the new variety is narrower and more upright than ‘Sheridan Spire’.
‘Urban Spire’ can be compared to the commercial variety Metasequoia glyptostroboides ‘National’, unpatented. The varieties are similar in most horticultural characteristics, however, trees of ‘Urban Spire’ differ in the following:
-
- 1. The new variety has a denser habit with shorter growth nodes.
- 2. Branch angle of the new variety is 45 degrees from center, or more acute, ‘National’ has a broader branch angle.
- 3. Overall habit of the new variety is narrower and more upright than ‘National’.
The accompanying photograph in FIG. 1 illustrates in full color a typical tree of ‘Urban Spire’ grown outdoors in Malvern, Pa. at approximately 10 years of age, during Summer.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Urban Spire’ trees grown outdoors in Malvern, Pa. Trees are approximately 10 years years old, planted in the ground.
