Abstract
A new cultivar of Buxus, ‘SB 300’, that is characterized by its tight, upright and very compact plant habit, its foliage that are dark green in color, and its new growth that is new growth that is fresh and vigorous.
Description
Botanical classification: Buxus microphylla var. japonica.
Variety denomination: ‘SB 300’.
The present invention relates to a new and distinct cultivar of Buxus microphylla var. japonica and will be referred to hereafter by its cultivar name, ‘SB 300’. ‘SB 300’ is a new cultivar of boxwood grown for use as an ornamental landscape plant.
The Inventor discovered the new cultivar in summer of 2007 as a new and unique plant in a container block of Buxus microphylla ‘Wintergreen’ (not patented) in his nursery in Piney River, Va. As the containers had been planted with stem cuttings of ‘Wintergreen’, it is presumed that the new cultivar arose as a branch mutation of ‘Wintergreen’.
Asexual propagation of the new cultivar was first accomplished by the Inventor by stem cuttings in summer of 2008 in Piney River, Va. Asexual propagation of the new cultivar by stem cuttings has determined that the characteristics are stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘SB 300’ as a unique cultivar of Buxus.
-
- 1. ‘SB 300’ exhibits a tight, upright and very compact plant habit.
- 2. ‘SB 300’ exhibits foliage that are dark green in color.
- 3. ‘SB 300’ exhibits new growth that is fresh and vigorous.
The parent plant of ‘SB 300’, ‘Wintergreen’, differs from ‘SB 300’ in having new growth that is less fresh and vigorous, a more open, spreading and loose growth habit, and leaves that are paler green in color. ‘SB 300’ can be most closely compared to Buxus microphylla cultivars ‘Wintergem’ (not patented) and ‘Jim Stauffer’ (not patented). ‘Wintergem’ is similar to ‘SB 300’ in leaf size and shape and cold hardiness. ‘Wintergem’ differs from ‘SB 300’ in having a less compact, less upright plant habit, foliage that is less dense, and foliage that is lighter green in color. ‘Jim Stauffer’ is similar to ‘SB 300’ in overall growth rate and cold hardiness. ‘Jim Stauffer’ differs from ‘SB 300’ in having a less tight growth habit, a less upright plant habit and foliage that is lighter green in color.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Buxus. The photographs were taken of two-year-old plants as grown in a cold frame (covered in plastic in winter) at a nursery in Piney River, Va. The photographs in FIG. 1 and FIG. 2 were taken of a plant 5 years in age.
The photograph in FIG. 1 provides a side view of ‘SB 300’.
The photograph in FIG. 2 provides a side view of the compact plant habit of ‘SB 300’ taken of a plant 6 years in age.
The photograph in FIG. 3 provides a close-up view of the new foliage growth of ‘SB 300’.
The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Buxus.
The following is a description of two-year-old plants of the new cultivar as grown in a cold frame (covered in plastic in winter) in one-gallon containers at a nursery in Piney River, Va. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
