Abstract

A new Aglaonema plant particularly distinguished by being intermediate in stature, leafy, compact, having an upright growth habit, and producing many basal branches and numerous leaves, is disclosed.

Description

Genus and species: Aglaonema hybrid.

Variety denomination: ‘TWYAG0004’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Aglaonema, botanically known as Aglaonema hybrid, and hereinafter referred to by the cultivar name ‘TWYAG0004’. The new cultivar originated from a hybridization made in Bogor, W. Java, Indonesia between A. commutatum var. tricolor (unpatented) and A. rotundum (unpatented) in October 1999.

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.

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; and
- 3. Produces many basal branches and numerous leaves.

DESCRIPTION OF PHOTOGRAPHS

This new Aglaonema plant is illustrated by the accompanying photographs which show overall plant habit and the upper and lower surface of a mature leaf. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1. shows the overall plant habit.

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

FIG. 3. shows a mature bud of an inflorescence.

The age of the plant in FIG. 1 and FIG. 2 is 10 months old. The age of the plant in FIG. 3 is 2 years old.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0004’. 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 four-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 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).
