<i>Echeveria </i>plant named ‘AMIECH2106’

Abstract

A new and distinct Echeveria hybrid plant named ‘AMIECH2106’ which is characterized by succulent foliage loosely arranged in a basal rosette, strongly glaucous foliage at and near the center of the rosette with a very light blue-grey to greyed-green general appearance that becomes progressively darker blue-grey to greyed-green as the foliage matures towards the outer whorls of the rosette, near-white foliar margins at and near the center of the rosette that become suffused with greyed-purple as the foliage matures towards the outer whorls of the rosette, and the stability of these characteristics from generation to generation.

Claims

BOTANICAL DESCRIPTION OF THE PLANT

(5) The following observations and measurements made in February of 2022 describe averages from a sampleset of six specimens of 25-week-old ‘AMIECH2106’ 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. ‘AMIECH2106’ 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).
