Description

Genus and species: Aglaonema commutatum×A. rotundum hybrid.

Variety denomination: ‘TWYAG0001’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Aglaonema, botanically known as Aglaonema commutatum×A. rotundum hybrid, and hereinafter referred to by the cultivar name ‘TWYAG0001’. The new cultivar originated from an open pollination made in Bogor, W. Java, Indonesia. A cross was made in October 2000 and a single plant was selected for further evaluation and asexual propagation in August 2002.

The new cultivar was created in Bogor, W. Java, Indonesia and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Apopka, Fla. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in the European Union in early September 2007. ‘TWYAG0001’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

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

    • 1. Intermediate in stature;
    • 2. Leafy, compact and upright branched growth habit;
    • 3. Vigorous;
    • 4. Excellent indoor keeping quality; and
    • 5. Somewhat more rapid growth rate than typical commercial Aglaonema cultivars.

DESCRIPTION OF PHOTOGRAPHS

This new Aglaonema plant is illustrated by the accompanying photographs which show overall plant habit and leaves. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 2 shows the upper and lower surface of a mature leaf.

 DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0001’. The data which define these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 18-month-old plants started from a single 4-leaf rooted cutting, still in a vegetative state and grown in Apopka, Fla. Rooted cuttings were planted in 20-cm pots and grown in a greenhouse in July 2006. The average daily temperature was about 85° to 95° F. and the average nightly temperature was about 72° to 78° F. The light level was about 1500 to 3000 foot candles. The plants were pinched twice. 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).
