plant named ‘AMILAPGO’

‘AMILAPGO’ is a new and distinctive Alocasia plant which is characterized by dark yellow-green foliage that is irregularly blotched and flecked with light yellow and borne on conspicuously variegated petioles, mature petioles which exhibit a plurality of greyed-purple broken and irregular transverse lines, resembling a zigzag pattern, at and near the base, and the stability of all 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 Alocasia macrorrhizos.

Variety denomination: The inventive variety of Alocasia disclosed herein has been given the variety denomination ‘AMILAPGO’.

BACKGROUND OF THE INVENTION

Parentage: The new plant originated as a spontaneous, partial-plant mutation. The mutation was discovered at a greenhouse in Homestead, Florida, in July of 2021, growing amongst a plurality of cultivated unnamed Alocasia macrorrhizos plants (not patented) which typified the species. The mutation exhibited conspicuously variegated foliage relative to the parent. The mutated plant shoot was harvested from the mother plant, repotted, and grown for an additional four months, approximately, in order to evaluate stability and uniqueness of the characteristics first observed. Upon confirmation of the stability and uniqueness, the new plant was selected for commercialization and given the name, ‘AMILAPGO’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMILAPGO’, by way of vegetative division of the plant shoots, was first initiated in October of 2021 in Homestead, Florida. Eight successive generations so produced have shown that the unique features of the instant plant cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘AMILAPGO’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Alocasia cultivar ‘AMILAPGO’. These traits, in combination, distinguish ‘AMILAPGO’ as a new and distinct cultivar.

    • 1. Alocasia ‘AMILAPGO’ exhibits a large plant size with very large, cordate laminas borne on long petioles that arise directly from the base of the plant; and
    • 2. Alocasia ‘AMILAPGO’ exhibits conspicuously variegated petioles with juvenile petioles that are light yellow with yellow-green irregular longitudinal streaking and mature petioles that are yellow-green with light yellow irregular longitudinal streaking; and
    • 3. Alocasia ‘AMILAPGO’ exhibits greyed-purple broken and irregular transverse lines, resembling a zigzag pattern, on the lower portion of mature petioles; and
    • 4. Alocasia ‘AMILAPGO’ exhibits dark yellow-green foliage that is irregularly blotched and flecked with light yellow; and
    • 5. Alocasia ‘AMILAPGO’ exhibits sporadic blistering of the epidermis in the form of irregularly shaped, translucent-white blotches.

BRIEF DESCRIPTION OF THE FIGURES

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

FIG. 1 shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, an exemplary plant of the new cultivar, ‘AMILAPGO’. The plant shown is approximately 18 months old, grown in a 25-liter nursery container at a commercial nursery in Homestead, Florida.

FIG. 2 shows the greyed-purple irregular transverse lines of the mature petioles of ‘AMILAPGO’.

FIG. 3 shows the adaxial surface of the mature foliage of ‘AMILAPGO’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in October of 2023 describe an 18-month-old ‘AMILAPGO’ plant grown in a 25-liter nursery container at a commercial nursery in Homestead, Florida. Said plant was produced under 63 percent shade, using conventional production protocols for Alocasia species. Cultural practices consisted of overhead irrigation once the top 5 cm of potting media becomes dry, seasonal applications of a 18-8-12 slow-release granular fertilizer, and preventative applications of insecticide and fungicide.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMILAPGO’ 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 measurements 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, third edition.

A botanical description of ‘AMILAPGO’ and comparisons with the parent plant and the most similar variety of common knowledge are provided below.
