A new and distinct cultivar of Thuja plant named ‘SMTOBP’, characterized by its upright plant habit; narrow columnar plant form; vigorous growth habit; dense and bushy form; bright green-colored developing leaves; bright green coloration maintained during the winter; and good winter hardiness and wind resistance.
Botanical designation: Thuja occidentalis.
Cultivar denomination: ‘SMTOBP’.
The present invention relates to a new and distinct cultivar of Thuja plant, botanically known as Thuja occidentalis, commonly known as American Arborvitae and hereinafter referred to by the name ‘SMTOBP’.
The new Thuja plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new Thuja plants with a compact plant habit.
The new Thuja plant originated from an open-pollination during the spring of 2003 of the Thuja occidentalis ‘Brandon’, not patented, as the female, or seed parent and an unknown selection of Thuja occidentalis as the male, or pollen, parent. The new Thuja plant was discovered and selected by the Inventor during the spring of 2006 as a plant within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Grand Haven, Mich.
Asexual reproduction of the new Thuja plant by hardwood cuttings in a controlled environment in Grand Haven, Mich. since November, 2007, has shown that the unique features of this new Thuja plant are stable and reproduced true to type in successive generations.
Plants of the new Thuja have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘SMTOBP’. These characteristics in combination distinguish ‘SMTOBP’ as a new and distinct Thuja plant:
Plants of the new Thuja can be compared to plants of the female parent, ‘Brandon’. Plants of the new Thuja differ primarily from plants of ‘Brandon’ in the following characteristics:
Plants of the new Thuja can be compared to plants of Thuja occidentalis, ‘DeGroot's Spire’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Thuja differed primarily from plants of ‘DeGroot's Spire’ in the following characteristics:
The aforementioned photograph and following observations, measurements and values describe plants grown during the spring and summer in ground beds in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial Thuja plant production. The plant in the photograph is seven years old and the plants used for the description were two years old.
