USPP19214P2 - Philodendron plant named ‘TWYPH0007’ - Google Patents

Abstract

A new Philodendron plant particularly distinguished by yellowish-green to green and dense foliage, a compact growth habit and ovate to narrow-ovate shaped foliage with pinnatifid margins and deep lobes, is disclosed.

Description

Genus and species: Philodendron selloum.

Variety denomination: ‘TWYPH0007’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of philodendron plant, botanically known as Philodendron selloum, and hereinafter referred to by the cultivar name ‘TWYPH0007’. The new cultivar is the result of a somaclonal variant of Philodendron selloum ‘Winterbourn’ (U.S. Plant Pat. No. 7,030) from approximately 10,000 micropropagated plants of the original cultivar in 1999 in Nonthaburi, Thailand.

The new cultivar was created in 1999 in Nonthaburi, Thailand and has been asexually reproduced repeatedly by micropropagation and division in Nonthaburi, Thailand over an eight-year period. ‘TWYPH0007’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Nonthaburi, Thailand.

• • 1. Yellowish-green to green-colored and dense foliage;
  • 2. A compact growth habit; and
  • 3. Ovate to narrow-ovate shaped foliage with pinnatifid margins and deep lobes.

DESCRIPTION OF THE PHOTOGRAPHS

This new philodendron plant is illustrated by the accompanying photographs which show the overall plant habit and the immature and mature foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 7-year-old plant with immature and mature foliage grown under 50% shade conditions outdoors in Nonthaburi, Thailand.

FIG. 1 shows the overall plant habit.

FIG. 2 shows the upper surface of an immature leaf.

FIG. 3 shows the lower surface of an immature leaf.

FIG. 4 shows the upper surface of a mature leaf.

FIG. 5 shows the lower surface of a mature leaf.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘TWYPH0007’. The data which define these characteristics were collected from asexual reproductions carried out in Nonthaburi, Thailand. The plant history was taken on 7-year-old plants having two suckers and grown under 50% shade conditions in Nonthaburi, Thailand. Color readings were taken under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

    • Height (from soil line to the top).—70 cm to 90 cm.
    • Width.—90 cm to 110 cm.
• Stem:
  • • Average number per plant.—1.
    • Diameter (for a 7 -year-old plant).—3.0 cm to 3.5 cm.

    • Venation and midrib color (immature leaves).—Upper surface: RHS 150B. Lower surface: RHS 179D, with the midrib-petiole joint flushed with RHS 171C.
    • Venation color (mature leaves).—Upper surface: RHS 141C. Lower surface: RHS 139D with the midrib-petiole joint flushed with RHS 183C.
    • Petiole (from fourth expanded leaf from the apex).—Aspect: Straight, about 30 degrees to 40 degrees from the vertical axis. Length: 35 cm to 40 cm. Diameter (mid-section): 0.5 cm to 0.7 cm. Immature color: RHS 154B and proximal end near RHS 171C. Mature color: RHS 144B and proximal end near RHS 183C. Texture: Smooth.

• Disease and insect resistance: No particular resistance or susceptibility has been observed.

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘TWYPH0007’ differs from the parental cultivar ‘Winterbourn’ (U.S. Plant Pat. No. 7,030) in that ‘TWYPH0007’ has yellowish-green to green foliage, while ‘Winterbourn’ has green foliage. Additionally, the growth rate of ‘TWYPH0007’ is approximately 10% to 15% lower than that of ‘Winterbourn’.

‘TWYPH0007’ differs from the commercial cultivar ‘Pastel Sport #2’ (U.S. Plant Pat. No. 16,123) in that ‘TWYPH0007’ has immature leaves which are yellowish-green with light greyed-red venation, while ‘Pastel Sport #2’ has immature leaves that are yellow-orange with pink venation. Additionally, ‘TWYPH0007’ has a longer internode length (1.5 cm to 3 cm) and leaves that have an acumiate apex and truncate base, while ‘Pastel Sport #2’ has a shorter internode (0.5 cm to 1.0 cm) and leaves that have an acute apex and hastate base.
