plant named ‘AMIECH2005’

- Novoami B.V.

A new and distinct Echeveria hybrid plant named ‘AMIECH2005’ which is characterized by a relative abundance of long, narrow oblanceolate foliage that is loosely arranged in a basal rosette, green to greyed-green glaucous foliage that is covered with greyed-purple epicuticular wax which gives the foliage a blue-grey appearance, older foliage at the outer whorls of the rosette that has a light greyed-green appearance on the upper surface and an olive-green appearance on the lower surface, foliage that is tipped greyed-purple, and the stability of these characteristics from generation to generation.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2020/2978, filed Nov. 25, 2020, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIECH2005’ is an interspecific hybrid seedling selection resulting from the controlled pollination of an unnamed Echeveria elegans plant (not patented), the seed parent, with an Echeveria carnicolor x E. affinis ‘Serrana’ plant (not patented), the pollen parent. The crossing was made by the inventor in the summer of 2017 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the autumn of 2018, 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, ‘AMIECH2005’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIECH2005’, by way of rooting leaf cuttings, was first initiated in the winter of 2018-2019 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.

SUMMARY OF THE INVENTION

The cultivar ‘AMIECH2005’ 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 ‘AMIECH2005’. These characteristics in combination distinguish ‘AMIECH2005’ as a new and distinct Echeveria hybrid cultivar:

    • 1. ‘AMIECH2005’ exhibits a flattened to flattened globular plant profile with foliage loosely arranged in a basal rosette; and
    • 2. ‘AMIECH2005’ exhibits a relative abundance of long, narrow oblanceolate foliage that is curled upward towards the apex of the lamina; and
    • 3. ‘AMIECH2005’ exhibits green to greyed-green juvenile and mature foliage that is covered with a layer of greyed-purple epicuticular wax which gives the foliage a blue-grey appearance; and
    • 4. ‘AMIECH2005’ exhibits an epicuticular waxy layer on the adaxial surface of the mature foliage that becomes progressively thinner towards the outermost whorls of the rosette, giving the oldest foliage a light greyed-green general appearance; and
    • 5. ‘AMIECH2005’ exhibits older foliage at the outermost whorls of the rosette that is lightly suffused with greyed-orange on the distal portion of the adaxial surface, with a very thin layer of epicuticular wax, giving the foliage an olive-green general appearance; and
    • 6. ‘AMIECH2005’ exhibits margins of the mature foliage in the outermost whorls of the rosette that are occasionally lightly suffused with greyed-orange, distally; and
    • 7. ‘AMIECH2005’ exhibits juvenile and mature foliage that is tipped greyed-purple.

 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 20 week-old ‘AMIECH2005’ 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. ‘AMIECH2005’ 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).
