Anthurium plant named ‘TWYANBP5’

Abstract

A new Anthurium plant particularly distinguished by having numerous, large for type, glossy, medium-pink spathes, durable, shiny leaves and is easy to grow, is disclosed.

Description

Genus and species: Anthurium hybrid.

Variety denomination: ‘TWYANBP5’

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 ‘TWYANBP5’. The new cultivar originated from a hybridization made in March of 2004 in Apopka, Fla., USA. The female parent was the proprietary Anthurium plant ‘Ruby Gem’ (unpatented), while the male parent was the Anthurium plant ‘Gemini’ (U.S. Plant Pat. No. 10,043).

The new cultivar was selected in May of 2006 from the results of the hybridization and has been asexually reproduced repeatedly by tissue culture in Apopka, Fla., USA. 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 for type, glossy, medium-pink spathes;
  • 2) Durable, shiny leaves; and
  • 3) 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 an 18-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 ‘TWYANBP5’. 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 which were planted from tissue culture in 25-cm pots and grown in a greenhouse with average daily temperatures of 85° C.-95° F. and average nightly temperatures of 72° C. 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 RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).
