Abstract

A new and distinct variety of Ficus plant named ‘ESPE1901’ which is characterized by the combination of large leaves held upright on a medium-sized plant, dark green leaves with prominent light green venation, 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 Ficus benghalensis.

Variety denomination: The inventive variety of Ficus disclosed herein has been given the variety denomination ‘ESPE1901’.

BACKGROUND OF THE INVENTION

Parentage: ‘ESPE1901’ originated as a naturally occurring, whole-plant mutation of an unnamed Ficus benghalensis plant (not patented). In February of 2014, the inventor discovered the mutation at his commercial greenhouse in Gravenzande, The Netherlands, growing amongst a cultivated population of Ficus benghalensis plants. The mutation was noted for its large, dark green leaves with prominent light green venation and was subsequently isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘ESPE1901’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of ESPE1901’, by way of stem cuttings, was first initiated in the summer of 2014 at a commercial greenhouse in Gravenzande, The Netherlands. 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 ‘ESPE1901’ has not been observed under all possible environmental conditions and 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 ‘ESPE1901’. These characteristics in combination distinguish ‘ESPE1901’ as a new and distinct Ficus cultivar:

    • 1. Ficus ‘ESPE1901’ exhibits large leaves held upright on a medium-sized plant; and
    • 2. Ficus ‘ESPE1901’ exhibits dark green leaves with prominent light green venation, particularly on the abaxial leaf surface.
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 ‘ESPE1901’ grown in a commercial greenhouse in Gravenzande, The Netherlands. This plant is approximately 25 weeks old, shown planted in a 19 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage of ‘ESPE1901’.

FIG. 3 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 of ‘ESPE1901’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements were made in February of 2019 and describe a sample set of six 25 week-old ‘ESPE1901’ plants grown in 19 cm nursery pots, two plants per container, at a greenhouse in Gravenzande, The Netherlands. Plants were produced in a greenhouse with full sun exposure, ebb and flood irrigation tables, no supplemental fertilizer, and no preventative or pest control measures utilized.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘ESPE1901’ 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, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
