<i>Echeveria </i>plant named ‘AMIECH2104’

Abstract

A new and distinct Echeveria agavoides plant named ‘AMIECH2104’ which is characterized by thick, durable foliage loosely arranged in a basal rosette, foliage that is conspicuously curled upward distally, light yellow-green to green juvenile foliage with very light greyed-green margins at the center of the rosette, foliage which becomes progressively darker as it matures, transitioning to dark greyed-green with greyed-orange foliar margins towards the outer whorls of the rosette, and the stability of these characteristics from generation to generation.

Claims

1. A new and distinct variety of Echeveria agavoides plant named ‘AMIECH2104’, substantially as described and illustrated herein.

This plant is approximately 35 weeks old, shown planted in a 12 cm container.

(2) 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 ‘AMIECH2104.

(3) 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 ‘AMIECH2104’.

(4) 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 ‘AMIECH2104’.

BOTANICAL DESCRIPTION OF THE PLANT

(5) The following observations and measurements made in February of 2022 describe averages from a sample set of six specimens of 35-week-old ‘AMIECH2104’ plants grown in 12 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.

(6) Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIECH2104’ 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).
