Abstract

A new and distinct Echeveria hybrid plant named ‘AMIECH2006’ which is characterized by a relative abundance of small, slightly concaved foliage that is arranged in a compact basal rosette, green foliage that is covered with greyed-green epicuticular wax, mature foliage that is tipped greyed-red, and the stability of these 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 Echeveria hybrid.

Variety denomination: The inventive variety of Echeveria hybrid disclosed herein has been given the variety denomination ‘AMIECH2006’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2020/2914, filed Nov. 19, 2020, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIECH2006’ is an interspecific hybrid seedling selection resulting from the controlled pollination of an Echeveria elegans ‘Rose’ plant (not patented), the seed parent, with an Echeveria hybrid ‘Slamrock’ plant (not patented), the pollen parent. The crossing was made by the inventor in the summer of 2016 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the autumn of 2017, one seedling was observed which exhibited unique growth and foliage characteristics. The seedling was isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘AMIECH2006’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIECH2006’, by way of rooting leaf cuttings, was first initiated in the spring of 2018 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIECH2006’ 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 ‘AMIECH2006’. These characteristics in combination distinguish ‘AMIECH2006’ as a new and distinct Echeveria hybrid cultivar:

• • 1. ‘AMIECH2006’ exhibits an abundance of relatively small foliage arranged in a compact basal; and
  • 2. ‘AMIECH2006’ exhibits slightly concaved, obovate to broadly oblanceolate foliage; and
  • 3. ‘AMIECH2006’ exhibits green juvenile foliage that is narrowly margined with a translucent yellow-green and moderately covered with greyed-green epicuticular wax; and
  • 4. ‘AMIECH2006’ exhibits green mature foliage is narrowly margined with greyed-green and moderately covered with greyed-green epicuticular wax tipped with greyed-red.
  • 5. ‘AMIECH2006’ exhibits mature foliage that is tipped with greyed-red.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage arrangement of ‘AMIECH2006’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage ‘AMIECH2006’.

FIG. 4 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the abaxial surface of the mature foliage ‘AMIECH2006’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in June of 2021 describe averages from a sample set of six specimens of 25 week-old ‘AMIECH2006’ plants grown in 8.5 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Echeveria plants which consisted of minimal irrigation and fertilizer applications, and 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. ‘AMIECH2006’ 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, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
