Abstract

A new cultivar of Campsis hybrid, ‘Takarazuka Yellow’, characterized by its very dark green, clean foliage, its large flowers that are peach orange in color when they open and mature to yellow in color with throats that are orange-red with red veining, and its compact, upright and vining plant habit.

Description

Botanical classification: Campsis×tagliabuana.

Variety denomination: ‘Takarazuka Yellow’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is co-pending with U.S. Plant Patent Applications related to plants derived from the same breeding program. The Applications are entitled; Campsis Plant Named ‘Takarazuka Zujin’ (U.S. Plant patent application Ser. No. 13/385,116)* and Campsis Plant Named ‘Takarazuka Fresa’ (U.S. Plant patent application Ser. No. 13/385,122)*.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campsis×tagliabuana (C. grandiflora×C. radicans) and will be referred to hereafter by its cultivar name, ‘Takarazuka Yellow’. ‘Takarazuka Yellow’ is a new cultivar of perennial vine for use as a landscape plant.

‘Takarazuka Yellow’ originated as a seedling that arose from seed planted from an open pollination of unnamed plants of Campsis×tagliabuana from the Inventor's breeding line in Shizuoka Prefecture Takarazuka, Japan in 1995. The parents are therefore unknown. The new Campsis was selected as a single unique plant in 2000.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2008 in Takarazuka, Japan. The characteristics of the new cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as grown outdoors in trial beds and in containers in Takarazuka, Japan. These attributes in combination distinguish ‘Takarazuka Yellow’ as a unique cultivar Campsis.

- 1. ‘Takarazuka Yellow’ exhibits very dark green, clean foliage.
- 2. ‘Takarazuka Yellow’ exhibits large flowers that are peach orange in color when they open and mature to yellow in color, throats are orange-red with red veining.
- 3. ‘Takarazuka Yellow’ exhibits a compact, upright vining plant habit.
  ‘Takarazuka Yellow’ can be most closely compared to cultivars derived from the same breeding program; ‘Takarazuka Fresa’, ‘Takarazuka Zujin’ and ‘Takarazuka Gold’ (not patented). ‘Takarazuka Fresa’ differs from ‘Takarazuka Yellow’ in flowers that are red in color and smaller in size. ‘Takarazuka Zijin’ differs from ‘Takarazuka Yellow’ in having flowers that are coral red in color and in having a longer bloom season. ‘Takarazuka Gold’ differs from ‘Takarazuka Yellow’ in having flowers that are smaller, lighter and less orange in color, in having a less compact plant habit, and in having foliage that is lighter green. ‘Takarazuka Yellow’ can also be compared to the cultivar ‘Kudian’ (U. S. Plant Pat. No. 13,139). ‘Kudian’ differs from ‘Takarazuka Yellow’ in having flowers that are more orange in color with orange-red throats and in having pubescent leaves.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of a one year-old plant of the new Campsis as grown outdoors in a one-gallon container in Takarazuka, Japan.

The photograph in FIG. 1 provides a view of a cluster of flowers of ‘Takarazuka Yellow’.

The photograph in FIG. 2 provides a close-up view of a flower of ‘Takarazuka Yellow’.

The colors in the photographs are as close as possible with the digital photography techniques utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Campsis.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of one year-old plants of the new Campsis as grown outdoors in one-gallon containers in Takarazuka, Japan.
