Abstract
A new and distinct variety of Crassula plant named ‘AMICRA1701’ which is characterized by the combination of a broad spreading to upright and freely-branching growth habit, an abundance of strong and thick foliage, glaucous greyed-green foliage which is margined and sparsely dotted red, and the stability of all characteristics from generation to generation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Crassula arborescens.
Variety denomination: The inventive variety of Crassula disclosed herein has been given the variety denomination ‘AMICRA1701’.
This application claims priority to the Community Plant Variety Rights application number 2017/1946, filed Aug. 9, 2017, which is herein incorporated by reference.
Parentage: ‘AMICRA1701’ originated as a naturally occurring, branch mutation of an unnamed Crassula arborescens plant (not patented). In November 2016, the inventor discovered the mutation at his commercial greenhouse in Heerhugowaard, The Netherlands, growing amongst a cultivated population of Crassula arborescens plants. The mutated branch was noted for its greyed-green foliage with red margins. Cuttings were taken from the mutated branch, rooted, and then grown out for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘AMICRA1701’ was selected for commercialization in January of 2017.
Asexual Reproduction: Asexual reproduction of ‘AMICRA1701’, by way of stem cuttings, was first initiated in January of 2017 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through four subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The cultivar ‘AMICRA1701’ has not been observed under all possible environmental conditions and 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 ‘AMICRA1701’. These characteristics in combination distinguish ‘AMICRA1701’ as a new and distinct Crassula cultivar:
-
- 1. Crassula ‘AMICRA1701’ exhibits a freely branching, broad to upright growth habit; and
- 2. Crassula ‘AMICRA1701’ exhibits an abundance of strong, thick foliage; and
- 3. Crassula ‘AMICRA1701’ exhibits glaucous greyed-green foliage which is margined and sparsely dotted red.
The following observations and measurements made in October of 2017 describe averages from a sample set of six specimens of 6 month-old ‘AMICRA1701’ plants grown in 17 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Crassula plants which consisted of minimal irrigation and fertilizer applications, as well as chemical pest and disease control measures against mealy bug and Botrytis as required. Plants were grown under approximately 50 percent shade after propagation and later exposed to full sun once they began to mature. No photoperiodic treatments or artificial light was given to the plants.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMICRA1701’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
