plant named ‘TSAECH1708’

- Tosjami B.V.

A new and distinct Pachyveria plant named ‘TSAECH1708’ which is characterized by small, broad obovate foliage arranged in a basal rosette, foliage which is very upright at the center of the rosette and becoming progressively more relaxed towards the outer whorls of the rosette, glaucous greyed-green foliage with a pinkish hue towards the distal end, as well as 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 Pachyphytum caeruleas x Echeveria lilacina which is also known by the nothogenus, x Pachyveria spp. (hereinafter referenced as, “Pachyveria”).

Variety denomination: The inventive variety of Pachyveria hybrid disclosed herein has been given the variety denomination ‘TSAECH1708’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/2391, filed Sep. 27, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘TSAECH1708’ is an intergeneric hybrid seedling selection resulting from the controlled pollination of an unnamed Pachyphytum caerulia plant (not patented), the seed parent, with an unnamed Echeveria lilacina plant (not patented), the pollen parent. The crossing was made by the inventor in the spring of 2015 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the spring of 2016, 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, ‘TSAECH1708’ was selected for commercialization in the autumn of 2016.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘TSAECH1708’, by way of rooting leaf cuttings, was first initiated in the spring 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 ‘TSAECH1708’ 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 ‘TSAECH1708’. These characteristics in combination distinguish ‘TSAECH1708’ as a new and distinct Pachyveria cultivar:

    • 1. ‘TSAECH1708’ exhibits small, succulent foliage arranged in a basal rosette; and
    • 2. ‘TSAECH1708’ exhibits broad obovate foliage which is curved upwards; and
    • 3. ‘TSAECH1708’ exhibits foliage which is very upright at the center of the rosette, becoming progressively more relaxed towards the outer whorls of the rosette; and
    • 4. ‘TSAECH1708’ exhibits glaucous greyed-green foliage with a light pinkish hue towards the distal end.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘TSAECH1708’ grown in a commercial greenhouse in Heerhugowaard, the Netherlands. This plant is approximately 6 months old, shown planted in an 8.5 cm container.

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 ‘TSAECH1708’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical mature foliage of ‘TSAECH1708’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in August of 2018 describe averages from a sample set of six specimens of 6 months old ‘TSAECH1708’ 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 and Pachyphytum 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. ‘TSAECH1708’ 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).

A botanical description of ‘TSAECH1708’ and comparisons with the parent plants and closest known comparator are provided below.

  • Plant description:
      • Growth habit.—Succulent perennial with foliage growing in a non-branched basal rosette.
