plant named ‘PT-DF-14’

Abstract

A new cultivar of Ficus carica plant named ‘PT-DF-14’ that is characterized by its compact, very dwarf, and semi-upright and mounded plant habit, its prolific production of fruit that is present at all branch nodes, its fruit production that commencing very early; as soon as dormancy breaks, and continues to produce fruit until dormancy or year around if plants do not go dormant, and its good performance as a container plant due to its size.

Description

Botanical classification: Ficus carica.

Variety denomination: ‘PT-DF-14’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ficus carica. The new Ficus will hereafter be referred to by its cultivar name, ‘PT-DF-14’. ‘PT-DF-14’ is a new cultivar of deciduous shrub grown for use as an ornamental and fruit bearing plant suitable for growing in containers.

The Inventor discovered the new cultivar in September of 2010 as a naturally occurring branch mutation of Ficus ‘Chicago Hardy’ (not patented) that was growing in a container in a production block in Kintnersville, Pa.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in May of 2014 in Kintnersville, Pa. Asexual propagation by stem cuttings, tissue culture arid layering has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘PT-DF-14’ as a unique cultivar of Ficus.

• • 1. ‘PT-DF-14’ exhibits a compact, very dwarf, and semi-upright and mounded plant habit.
  • 2. ‘PT-DF-14’ exhibits prolific production of fruit that is present at all branch nodes.
  • 3. ‘PT-DF-14’ exhibits fruit production that commencing very early; as soon as dormancy breaks, and continues to produce fruit until dormancy or year around if plants do not go dormant.
  • 4. ‘PT-DF-14’ exhibits good performance as a container plant due to its size.

‘Chicago Hardy’, the parent of ‘PT-DF-14’, differs from ‘PT-DF-14’ in having a much larger plant size, in producing fruits in late summer that ripen very late in fall (often not before frost), in having longer branch internode lengths, and a more open upright plant habit. ‘PT-DF-14’ can be most closely compared to the Ficus cultivars ‘Little Miss Figgy’ (U.S. Plant Pat. No. 27,929) and ‘Beer's Black’ (not patented). ‘Little Miss Figgy’ differs from ‘PT-DF-14’ in having a much larger plant height, in producing much fewer fruits that ripen at the end of the season, and in having a more open and more upright plant habit. ‘Beer's Black’ differs from ‘PT-DF-14’ in being a small tree with a much larger plant height, and in producing fruit in one flush late in the season.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three-year-old plants of the new cultivar as grown outdoors in 3-gallon containers in Kintnersville, Pa. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
