Botanical designation: Chamaecyparis species.
Cultivar denomination: ‘RutCham1’.
The present invention relates to a new and distinct cultivar of Chamaecyparis, botanically known as Chamaecyparis pisifera, and hereinafter referred to by the cultivar name ‘RutCham1’.
The new Chamaecyparis ‘RutCham1’ is a product of open-pollenated seed from unknown cultivars received in 2013 from Poland (accession record 13-0152, unpatented). The seed was planted in the research field in Watkinsville, Georgia, on Oct. 25, 2014, identified as 3-12. After evaluating the growth habit, it was selected as trial number 2015-1 in 2015.
Asexual reproduction of the new Chamaecyparis ‘RutCham1’ using hardwood cuttings taken during the winter months has been continued in Watkinsville, GA since 2015. Observations of the resulting progeny have shown that the unique features of this new Chamaecyparis ‘RutCham1’ are stable and reproduced true to type in successive generations.
The new Chamaecyparis cultivar ‘RutCham1’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, water and fertility levels, soil types, and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique and distinguishing characteristics of the new Chamaecyparis cultivar named ‘RutCham1’. In combination, these traits set ‘RutCham1’ apart from all other existing varieties of Chamaecyparis known to the inventors.
Plants of the new Chamaecyparis can be compared to similar cultivar Chamaecyparis pisifera ‘Filifera Aurea’ (unpatented) and differ from ‘Filifera Aurea’ at least in that plants of the new Chamaecyparis have more vertical sprays, and branchlets are less pendulous, providing the more uniform, pyramidal shape. Also, the foliage on ‘Filifera Aurea’ is more threadlike than the foliage of the new Chamaecyparis ‘RutCham1’.
The accompanying, colored photographic illustrations show the overall appearance and distinct characteristics of the new cultivar of Chamaecyparis ‘RutCham1’ showing the colors as true as possible. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describes the colors of the new Chamaecyparis ‘RutCham1’. The photographs were taken in February 2023 of nine-year-old plants grown outdoors in Watkinsville, Georgia.

The following traits have been consistently observed in the original plant of this new variety and in asexually propagated progeny grown in Watkinsville, Georgia, and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety ‘RutCham1’.
Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon the R.H.S. Colour Chart, 5th edition published by The Royal Horticultural Society, London, England in 2007, except where general terms of ordinary dictionary significance are used.
The aforementioned photographs and following observations, measurements, and values describe plants of the Chamaecyparis cultivar named ‘RutCham1’. Data were collected from plants that were approximately eight years old and were grown in the ground under outdoor conditions in Watkinsville, GA. The average low temperatures ranged from lows of about 33° F. to 42° F. in the winter, to average high temperatures of about 85° F. to 92° F. in summer.
