Latin name of the genus and species: Chamaecyparis obtusa.
Variety denomination: ‘MonYur’.
The new cultivar is a product of chance discovery by the inventor, Pedro Guzman. This new variety, hereinafter referred to as ‘MonYur’, was selected as a naturally occurring, whole plant mutation from an unnamed, unpatented plant of Chamaecyparis obtusa. The novel variety was discovered in a commercial nursery in Dayton, Oreg. during August of 2010.
After identifying the new variety as a potentially interesting selection, first propagation of ‘MonYur’ occurred by hardwood cuttings at the same commercial nursery during February of 2011. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Three generations have been asexually reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.
The cultivar ‘MonYur’ 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 ‘MonYur’ These characteristics in combination distinguish ‘MonYur’ as a new and distinct Chamaecyparis cultivar:
‘MonYur’ is similar in most horticultural characteristics to the parent variety. Plants of the new cultivar ‘MonYur’ however, are distinctively more compact, with lower pruning requirements.
In addition to the seed parent, ‘MonYur’ can be compared to the commercial variety an unnamed plant of Chamaecyparis obtusa filicoides, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘MonYur’ are more compact, and require less pruning. Ultimate height of the new variety is 6 to 8 feet, mature height of the comparator is 8 to 10 feet. Branches of the new variety are more tightly arranged.
‘MonYur’ can be compared to the commercial variety an unnamed plant of Chamaecyparis obtusa gracilis, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘MonYur’ have a tighter, more compact plant form, requiring less pruning. Mature height of ‘MonYur’ is approximately 6 to 8 feet, mature height of this comparator is approximately 10 to 12 feet.
‘MonYur’ can be compared to the commercial variety an unnamed plant of Chamaecyparis obtusa compacta, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘MonYur’ produce more branches, in a denser pattern, forming a tighter, more compact plant form. Plants of the new variety grow more slowly, requiring less pruning. Mature height of ‘MonYur’ is approximately 6 to 8 feet, mature height of this comparator is approximately 10 to 12 feet.
