Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Geogenanthus ciliatus.
Variety denomination: The inventive variety of Geogenanthus disclosed herein has been given the variety denomination ‘CF-MKR-GR1’.
BACKGROUND OF THE INVENTION
Parentage: ‘CF-MKR-GR1’ is a spontaneous whole-plant mutation which was discovered growing amongst a cultivated population of unnamed Geogenanthus sp. plants (not patented) which was discovered by the inventor in August of 2019 at a commercial greenhouse near Miami, Fla. The mutation was first noted for its unique multicolored foliage variegation. At that time, the claimed plant was asexually propagated, and the resulting plants were grown to maturity in order to confirm the distinguishing characteristics first observed and the stability thereof.
Asexual Reproduction: Asexual reproduction of the new cultivar ‘CF-MKR-GR1’, by way of rooting leaf cuttings, was first performed in September of 2019 at a commercial greenhouse near Miami, Fla. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
SUMMARY OF THE INVENTION
The cultivar ‘CF-MKR-GR1’ 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 ‘CF-MKR-GR1’. These characteristics in combination distinguish ‘CF-MKR-GR1’ as a new and distinct Geogenanthus cultivar:
- 1. Geogenanthus ‘CF-MKR-GR1’ exhibits a compact growth habit with a flattened globular plant profile; and
- 2. Geogenanthus ‘CF-MKR-GR1’ exhibits relatively large, near-orbicular, glossy foliage borne terminally on very dark purple aerial shoots; and
- 3. Geogenanthus ‘CF-MKR-GR1’ exhibits multi-colored, variegated foliage with irregular streaks of color on the adaxial surface of both the juvenile and mature foliage which range from in between yellow-green and black, yellow-green, red-purple, and greyed-orange; and
- 4. Geogenanthus ‘CF-MKR-GR1’ exhibits juvenile and mature foliage with a variegated abaxial surface which is colored with irregular streaks of very dark purple, in between. purple and black, and dark red-purple.

BOTANICAL DESCRIPTION OF THE PLANT
The following observations and measurements, made in July of 2022, describe a 9-month-old ‘CF-MKR-GR1’ plant. The plant was grown from a single unrooted cutting, in 15 cm nursery containers, at a commercial greenhouse near Miami, Fla. The plant was produced using conventional greenhouse production protocols for Geogenanthus sp. which entailed growing plants under 80 percent shade, regularly watering with overhead irrigation, and fertilizing with a 180-day slow-release granular fertilizer. No chemical pest measures or photoperiodic treatments were utilized during production.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘CF-MKR-GR1’ 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, 1986 (third edition).
