Description

Botanical designation: Philodendron selloum.

Cultivar denomination: ‘LITTLE HOPE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Philodendron plant, botanically known as Philodendron selloum and hereinafter referred to by the name ‘Little Hope’.

The new Philodendron plant is a naturally-occurring whole plant mutation of Philodendron selloum ‘Hope’, not patented. The new Philodendron plant was discovered and selected by the Inventor in 2009 as a single plant from within a population of plants of ‘Hope’ in a controlled greenhouse environment in Waimanalo, Hi.

Asexual reproduction of the new Philodendron plant by micro-propagated cuttings in a controlled environment in Waimanalo, Hi. since 2010 has shown that the unique features of this new Philodendron plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Philodendron have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘Little Hope’. These characteristics in combination distinguish ‘Little Hope’ as a new and distinct Philodendron plant:

    • 1. Relatively compact, upright and mounding plant habit.
    • 2. Freely basal branching habit; dense and bushy plant form.
    • 3. Vigorous and robust growth habit.
    • 4. Relatively small dark green-colored leaves.
    • 5. Relatively resistant to pathogens common to Philodendron plants.

Plants of the new Philodendron differ from plants of the parent, ‘Hope’, in the following characteristics:

    • 1. Plants of the new Philodendron are more compact and denser than plants of ‘Hope’.
    • 2. Plants of the new Philodendron are more freely basal branching than plants of ‘Hope’.
    • 3. Plants of the new Philodendron have smaller leaves than plants of ‘Hope’.
    • 4. Plants of the new Philodendron have exhibited resistance to Dasheen Mosaic Virus and Erwinia whereas plants of ‘Hope’ are susceptible to Dasheen Mosaic Virus and Erwinia.

Plants of the new Philodendron can be compared to plants of Philodendron selloum ‘Winterbourn’, disclosed in U.S. Plant Pat. No. 7,030. Plants of the new Philodendron differ from plants of ‘Winterbourn’ in the following characteristics:

    • 1. Plants of the new Philodendron are more compact than plants of ‘Winterbourn’.
    • 2. Plants of the new Philodendron are more freely basal branching and denser than plants of ‘Winterbourn’.
    • 3. Leaves of plants of the new Philodendron have deeper sinuses than leaves of plants of ‘Winterbourn’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Philodendron plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Philodendron plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘Little Hope’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical plant of ‘Little Hope’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 25-cm containers in an outdoor nursery in Waimanalo, Hi. and under cultural practices typical of commercial Philodendron production. During the production of the plants, day temperatures ranged from 18° C. to 32° C., night temperatures ranged from 13° C. to 25° C. and light levels ranged from 7,000 to 18,000 foot-candles. Plants were nine months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
