USPP34851P2 - Ficus plant named ‘ESPE2007’ - Google Patents

Abstract

A new and distinct variety of Ficus cyathistipula plant named ‘ESPE2007’ which is characterized by the combination of a compact growth habit with a relatively fast rate of growth which makes it suited to production and sale in small container sizes, small leaves, prominent stipules, 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 cyathistipula Warb.

Variety denomination: The inventive variety of Ficus disclosed herein has been given the variety denomination ‘ESPE2007’.

BACKGROUND OF THE INVENTION

Parentage: ‘ESPE2007’ originated as a naturally occurring, whole-plant mutation of an unnamed Ficus cyathistipula plant (not patented). The inventor regularly discovers mutations of Ficus cyathistipula at his commercial greenhouse in 's-Gravenzande, the Netherlands and, as a result, a selection program was established with the goal of developing a new cultivar that would be more compact and suitable for production and sale in smaller container sizes. From 2017 through early 2018, more than 30 mutations were discovered and subsequently isolated for further observation. Each mutation was asexually propagated on three separate occasions and grown to maturity, in order to confirm the distinctness and stability of the characteristics first observed. In September of 2018, the candidate variety was ultimately selected from the 30 candidates due its compact growth habit, smaller leaves, and fast rate of growth which made it suitable for production in smaller container sizes, ranging from 14 to 21 centimeters.

Asexual Reproduction: Asexual reproduction of ESPE2007’, by way of stem cuttings, was first initiated in 2018 at a commercial greenhouse in 's-Gravenzande, the Netherlands. Through three subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ESPE2007’ 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 ‘ESPE2007’. These characteristics in combination distinguish ‘ESPE2007’ as a new and distinct Ficus cultivar:

• • 1. Ficus ‘ESPE2007’ exhibits a combination of a compact growth habit with a relatively fast rate of growth, making it suitable for production in smaller container sizes, ranging from 14 to 21 centimeters; and
  • 2. Ficus ‘ESPE2007’ exhibits relatively small, elliptic to near-oblong foliage; and
  • 3. Ficus ‘ESPE2007’ exhibits shortened internodal spacing; and
  • 4. Ficus ‘ESPE2007’ exhibits an abundance of prominent and persistent brown stipules present along both the main stem and lateral branches.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements were made in August of 2020 and describe a sample set of six 12 month-old ‘ESPE2007’ plants grown in 19 cm nursery pots, at a greenhouse in 's-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. ‘ESPE2007’ 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).
