Aglaonema plant named ‘TWYAG0022’

Abstract

A new Aglaonema plant particularly distinguished by having foliage that is medium to dark green and variably marked with spots and coalescing blotches of bright pink, primary veins that are pale green and flushed with pink, midribs that are pale green and variably tinged with pink, a dense, full, low spreading growth habit and intermediate in stature and yellow-green spathes, is disclosed.

Description

Genus and species: Aglaonema hybrid.

Variety denomination: ‘TWYAG0022’.

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 variety name as ‘TWYAG0022’. The new variety originated from an open pollination made in Bogor, West Java, Indonesia between unknown individual plants of Aglaonema (species unknown). The new variety was discovered as a single plant within the progeny of the stated open pollination in a controlled environment in Bogor, West Java, Indonesia.

The new variety was created in Bogor, West Java, Indonesia and has been asexually reproduced repeatedly by vegetative cuttings in Apopka, Fla. for two or more generations. 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 the new variety when grown under normal horticultural practices in Apopka, Fla.

• • 1. Foliage that is medium to dark green and variably marked with spots and coalescing blotches of bright pink;
  • 2. Primary veins are pale green and flushed with pink;
  • 3. Midrib is pale green and variably tinged with pink;
  • 4. Dense, full, low spreading growth habit and intermediate in stature; and
  • 5. Yellow-green spathes.

DESCRIPTION OF THE PHOTOGRAPH

This new Aglaonema plant is illustrated by the accompanying photograph which shows the overall plant habit and leaf color. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘TWYAG0022’. The data which define these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 12 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 15 cm pots and grown in a greenhouse in August 2006. The plants were pinched once. 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).
