Anthurium plant named ‘TWYANBD9’

Abstract

A new Anthurium plant particularly distinguished by having medium to large, triangular, red-pink, shiny spathes, contrasting, firm/leathery, very shiny, dark metallic leaves that become very dark green as they mature, and a dense, upright, branched, leafy growth habit, is disclosed.

Description

Genus and species: Anthurium hybrida.

Variety denomination: ‘TWYANBD9’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Anthurium, botanically known as Anthurium hybrid, and hereinafter referred to by the cultivar name ‘TWYANBD9’. The new cultivar originated from a hybridization made in 2003 in Apopka, Fla., USA. The female parent was the Anthurium plant, ‘Pink Paradise’ (U.S. Plant Pat. No. 11,657), while the male parent was the proprietary Anthurium plant ‘H-43’ (unpatented).

The new cultivar was selected in March 2005 from the results of the hybridization and has been asexually reproduced repeatedly by tissue culture in Apopka, Fla., USA over a two and one-half year period. 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) Medium to large, triangular, red-pink, shiny spathes;
  • 2) Contrasting, firm/leathery, very shiny, dark metallic leaves which become very dark green as they mature; and
  • 3) Dense, upright, branched, leafy growth habit.

DESCRIPTION OF PHOTOGRAPH

This new Anthurium plant is illustrated by the accompanying photograph which shows the overall plant habit including blooms, buds and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a 24-month old plant grown in a greenhouse in Apopka, Fla.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘TWYANBD9’. The data which define these characteristics were collected from asexual reproductions carried out in Apopka, Fla. The plant history was taken on 24-month old plants which were planted from tissue culture in 25-cm pots and grown in a greenhouse with average daily temperatures of 85° F.-95° F. and average nightly temperatures of 72° F. to 78° F. Observations were made in March 2007. Color readings were taken under natural light in the greenhouse. Color references are primary to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘TWYANBD9’ differs from the female parent Anthurium plant ‘Pink Paradise’ (U.S. Plant Pat. No. 11,657), by having narrower, shiny, red-pink spathes, while ‘Pink Paradise’ has very large, cordate pink spathes and lobes flushed with green. ‘TWYANBD9’ has immature leaves that are very dark with a metallic sheen and become dark-green with maturity, while ‘Pink Paradise’ has uniformly green leaves. ‘TWYANBD9’ has an upright, highly branched growth habit with outward pointing leaves, while ‘Pink Paradise’ has an upright, symmetrical and clumping growth habit that is less dense and has fewer basal branches.

‘TVMANBD9’ differs from the male parent Anthurium plant ‘H-43’ (unpatented) by having larger, shiny, red-pink spathes, while ‘H-43’ has smaller, shiny, very dark-red spathes. ‘TWYANBD9’ has an upright branched growth habit with outward pointing leaves, while ‘H-43’ has an upright, rounded growth habit that is less dense with fewer basal branches and larger leaves. In addition, ‘TYWANBD9’ is more tolerant of adverse conditions, while ‘H-43’ has spathes and foliage that tend to fade if the plant is exposed to high temperatures.

‘TWYANBD9’ differs from the commercial variety ‘Pippi’ (U.S. Plant Pat. No. 14,475), by having larger spathes that fold upward lengthwise, while ‘Pippi’ has smaller, flatter spathes. ‘TWYANBD9’ has shiny, red-pink spathes that are often tinged with green at the base, while ‘Pippi’ has uniformly red spathes that are not as shiny. In addition, ‘TWYANBD9’ has immature leaves that are very dark with a metallic sheen and become dark-green with maturity, while ‘Pippi’ has immature leaves that are green with darker veins.

‘TWYANBD9’ differs from the co-pending anthurium application ‘TWYANBD18’ (U.S patent application Ser. No. 11/906,501) in that ‘TWYANBD9’ has larger spathes (length is 12.0 cm to 20.0 cm and width is 8.0 cm to 10.0 cm) than ‘WYANBD18’ (length is 7.5 cm to 11.5 cm and width is 5. cm to 7.5 cm). Additionally, ‘TWYANBD9’ has longer peduncles (45.0 cm to 58.0 cm) than ‘TWYANBD18’ (45.0 cm).
