USPP33029P2 - Echeveria plant named ‘AMIECH1912’ - Google Patents

Abstract

A new and distinct Echeveria hybrid plant named ‘AMIECH1912’ which is characterized by broad obovate to spatulate foliage held somewhat loosely in a basal rosette, moderately glossy juvenile foliage, vibrant dark red juvenile foliage that is margined pink, slightly glossy mature foliage, very dark purple mature foliage that is narrowly margined pink, 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 ‘AMIECH1912’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2019/3324, filed Dec. 6, 2019, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘AMIECH1912’ is a naturally-occurring, spontaneous whole-plant mutation of Echeveria hybrid ‘AMIECH1604’ (U.S. Plant Pat. No. 29,312) which was discovered by the inventor in the summer of 2018 at a commercial greenhouse in Heerhugowaard, the Netherlands. The mutation was noted for its very dark purple foliage.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIECH1912’, by way of rooting leaf cuttings, was first initiated in the winter of 2018 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through two subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMIECH1912’ 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 ‘AMIECH1912’. These characteristics in combination distinguish ‘AMIECH1912’ as a new and distinct Echeveria hybrid cultivar:

• • 1. ‘AMIECH1912’ exhibits a flattened to flattened globular plant profile with foliage held somewhat loosely in a basal rosette which eventually forms a short, unbranched stem with age; and
  • 2. ‘AMIECH1912’ exhibits slightly concave, broad obovate to spatulate foliage with a bluntly apiculate apex; and
  • 3. ‘AMIECH1912’ exhibits moderately glossy, lightly glaucescent juvenile foliage; and
  • 4. ‘AMIECH1912’ exhibits greyed-purple juvenile foliage, generally appearing as a vibrant dark red general coloration with pink margins; and
  • 5. ‘AMIECH1912’ exhibits slightly glossy, lightly glaucescent mature foliage; and
  • 6. ‘AMIECH1912’ exhibits mature foliage that is colored in between greyed-purple and brown, generally appearing as very dark purple to nearly black; and
  • 7. ‘AMIECH1912’ exhibits mature foliage that is narrowly margined pink.

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 ‘AMIECH1912’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in January of 2020 describe averages from a sample set of six specimens of 8 months old ‘AMIECH1912’ 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.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIECH1912’ 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).
