Anthurium plant named ‘TWYANAG2’

Abstract

A new Anthurium plant particularly distinguished by having numerous, large, shiny, bright-orange spathes, numerous dark-green, durable, shiny leaves, an upright growth habit and by being easy to grow, is disclosed.

Description

Genus and species: Anthurium hybrida.

Variety denomination: ‘TWYANAG2’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Anthurium, botanically known as Anthurium hybrida, and hereinafter referred to by the cultivar name ‘TWYANAG2’. The new cultivar originated from a hybridization made in winter 2004 in Apopka, Fla., USA. The female parent was the proprietary Anthurium plant ‘Orange Cup’ (unpatented), while the male parent was the Anthurium plant ‘Orange Crush’ (U.S. Plant Pat. No. 12,316). The first propagation was done in the Summer of 2004.

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 for approximately two and one-half years. 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) Numerous, large, shiny, bright-orange spathes;
  • 2) Numerous, dark-green, durable, shiny leaves;
  • 3) Upright growth habit; and
  • 4) Easy to grow.

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 ‘TWYANAG2’. 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 primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘TWYANAG2’ differs from the female parent Anthurium plant ‘Orange Cup’ (unpatented), by having smaller, flatter, more numerous, bright-orange spathes and a purple spadix tinged with orange, while ‘Orange Cup’ has larger, lighter-orange, cupped spathes and a yellow-white spadix. ‘TWYANAG2’ has a larger, more upright growth habit, while ‘Orange Cup’ has a shorter, more compact growth habit. In addition, ‘TWYANAG2’ has darker-green, more durable and shinier leaves as well as immature leaves that are tinged with bronze, while ‘Orange Cup’ has leaves that are entirely lighter green and are prone to yellowing at high temperatures.

‘TWYANAG2’ differs from the male parent Anthurium plant ‘Orange Crush’ (U.S. Plant Pat. No. 12,316) by having smaller, flatter, more numerous bright orange spathes and inflorescences that are mostly clustered in the center of the plant and sit among or above the foliage, while ‘Orange Crush’ has slightly larger, fewer spathes that are more red-orange in color and inflorescences that are more outward leaning and sit higher above the foliage. In addition, ‘TWYANAG2’ has a larger more upright plant habit, while ‘Orange Crush’ has a shorter more compact plant habit.

‘TWYANAG2’ differs from the commercial variety ‘Orange Hot’ (unpatented), by having larger, longer lasting, bright-orange spathes, while ‘Orange Hot’ has smaller, pale-orange spathes that are less durable. ‘TWYANAG2’ has smaller leaves than ‘Orange Hot’. In addition, ‘TWYANAG2’ has a more prolific bloom than ‘Orange Hot’.
