USPP34256P2 - Echeveria plant named ‘AMIECH2009’ - Google Patents

Abstract

A new and distinct Echeveria hybrid plant named ‘AMIECH1009’ which is characterized by flat, oblanceolate to narrowly obovate foliage with an obtuse to cuspidate apex, crenulate foliar margins that are slightly to moderately undulated, yellow-green mature foliage is prominently margined with a translucent light greyed-green color, strongly glaucous juvenile and mature foliage that is heavily covered with a layer of greyed-green epicuticular wax on both the adaxial and abaxial surfaces which gives the foliage a paled greyed-green appearance with a cyanic hue, 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 lilacina x E. parva.

Variety denomination: The inventive variety of Echeveria hybrid disclosed herein has been given the variety denomination ‘AMIECH2009’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2021/0039, filed Jan. 6, 2021, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIECH2009’ is an interspecific hybrid seedling selection resulting from the controlled pollination of an unnamed Echeveria lilacina plant (not patented), the seed parent, with an unnamed Echeveria parva plant (not patented), the pollen parent. The crossing was made by the inventor in the spring of 2016 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the summer 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, ‘AMIECH2009’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIECH2009’, by way of rooting leaf cuttings, was first initiated in the autumn 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.

SUMMARY OF THE INVENTION

The cultivar ‘AMIECH2009’ 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 ‘AMIECH2009’. These characteristics in combination distinguish ‘AMIECH2009’ as a new and distinct Echeveria hybrid cultivar:

• • 1. ‘AMIECH2009’ exhibits a flattened to flattened globular plant profile with foliage somewhat loosely held in a basal rosette; and
  • 2. ‘AMIECH2009’ exhibits flat, oblanceolate to narrowly obovate foliage with an obtuse to cuspidate apex; and
  • 3. ‘AMIECH2009’ exhibits crenulate foliar margins that are slightly to moderately undulated; and
  • 4. ‘AMIECH2009’ exhibits yellow-green mature foliage that is prominently margined with a translucent light greyed-green color; and
  • 5. ‘AMIECH2009’ exhibits strongly glaucous juvenile and mature foliage that is heavily covered with a layer of greyed-green epicuticular wax on both the adaxial and abaxial surfaces which gives the foliage a pale greyed-green appearance with a cyanic hue.

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 ‘AMIECH2009’.

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 ‘AMIECH2009’.

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 ‘AMIECH2009’.

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 ‘AMIECH2009’ 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. ‘AMIECH2009’ 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).
