Abstract
A new cultivar of Buxus microphylla ‘Gregem’, characterized by its small evergreen leaves, its dense compact growth habit, its vigorous growth rate, its hardiness to U.S.D.A Zone 5, and its ease of propagation by softwood cuttings.
Description
Botanical classification: Buxus microphylla.
Variety denomination: ‘Gregem’.
The present invention relates to a new and distinct cultivar of Buxus microphylla and will be referred to hereafter by its cultivar name, ‘Gregem’. ‘Gregem’ is a new cultivar of boxwood grown for use as a container plant, hedging material and landscape shrub.
The new cultivar was discovered by one of the Inventors as a naturally occurring branch mutation of the cultivar ‘Winter Gem’ (not patented) growing in a container in a nursery in April 2000 in El Campo, Tex.
Asexual reproduction of the new cultivar was first accomplished by one of the Inventors using softwood stem cuttings in El Campo, Tex. in March 2002. The characteristics of ‘Gregem’ have been determined to be 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 as grown outdoors in trial beds and in containers in El Campo, Tex. These attributes in combination distinguish ‘Gregem’ as a unique cultivar of Buxus.
-
- 1. ‘Gregem’ exhibits small, evergreen leaves.
- 2. ‘Gregem’ exhibits a compact, dense growth habit with leaves held very closely together.
- 3. ‘Gregem’ exhibits a vigorous growth rate.
- 4. ‘Gregem’ is readily propagated by softwood cuttings.
- 5. ‘Gregem’ is hardy to U.S.D.A Zone 5.
‘Gregem’ can be most closely compared to ‘Winter Gem’, the parent plant. In comparison to ‘Winter Gem’, ‘Gregem’ is similar to ‘Winter Gem’ in having a dwarf and compact growth habit, however ‘Gregem’ differs from ‘Winter Gem’ in having leaves that are smaller in size, in exhibiting a growth habit that is more dense, and in having a more vigorous growth rate. ‘Gregem’ may also be compared to ‘Wintergreen’ (not patented). Both cultivars have evergreen leaves, however ‘Gregem’ differs from ‘Wintergreen’ in having smaller leaves, a denser growth habit and by maturing to a smaller sized plant.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of 3 year-old plants of the new Buxus as grown outdoors in three-gallon containers in El Campo, Tex.
The photograph in FIG. 1 is a side view and illustrates the overall plant habit and appearance of ‘Gregem’.
The photograph in FIG. 2 provides a close-up view of the foliage.
The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Buxus.
The following is a detailed description of 3 year-old plants of the new cultivar as grown outdoors in three-gallon containers in El Campo, Tex. 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
