USPP30468P2 - Bidens plant named ‘15S25’ - Google Patents

Abstract

A new cultivar of Bidens named ‘15S25’ that is characterized by its very compact plant habit, and its inflorescences that are orange-yellow in color.

Description

Botanical classification: Bidens triplinervia.

Variety denomination: ‘15S25’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Bidens Plant Named ‘15S27’ (U.S. Plant patent application Ser. No. 15/732,266).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidens triplinervia plant, botanically of hybrid origin and known as Bidens ‘15S25’ and will be referred to hereinafter by its cultivar name, ‘15S25’. The new cultivar of Bidens is an herbaceous perennial grown for landscape and container use.

‘15S25’ arose from crosses made by the Inventor in Quito, Equador between unnamed and unpatented proprietary plants of Bidens triplinervia from his breeding program. The seeds were pooled from the crosses and therefore the exact parents are unknown. ‘15S25’ was selected in 2014 as a single unique plant amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in 2014 in Quito, Equador. Asexual propagation by stem cuttings has shown that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘15S25’ as a unique cultivar of Bidens.

• • 1. ‘15S25’ exhibits a very compact plant habit.
  • 2. ‘15S25’ exhibits inflorescences that are orange-yellow in color.

‘15S25’ can be most closely compared to Bidens cultivars ‘Florbikano’ (U.S. Plant Pat. No. 25,087) and ‘15S27’. ‘Florbikano’ differs from ‘15S25’ in having a less compact plant habit and inflorecences that are smaller in size. ‘15S27’ is similar to ‘15S25’ in having a very compact plant habit. ‘15S27’ differs from ‘15S25’ in having red inflorescences.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Bidens. The photographs were taken of a 3 month-old plant of ‘15S25’ as grown in an unheated greenhouse in a 13-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘15S25’ and shows the plant habit in bloom.

The photograph in FIG. 2 provides a close-up view of the inflorecences of ‘15S25’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘15S25’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Bidens.
