<i>Campanula </i>plant named ‘CHAMELEON ROSE’

Abstract

A new and distinct cultivar of Campanula plant named CHAMELEON ROSE is disclosed, characterized by biennial plants producing sterile flowers. The unique new cultivar produces unique color-changing flowers, beginning green and white, developing a pink margin with age. Flowering stems have a vase life of 20 to 22 days. Flowers on the live plants have the novel characteristic of not fading after visits by pollinators. The new cultivar is a Campanula, typically produced as an outdoor ornamental plant or for cut flower purposes.

Claims

1. A new and distinct cultivar of Campanula plant named CHAMELEON ROSE as herein illustrated and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photograph in FIG. 1 illustrates in full color a close up a typical of CHAMELEON ROSE.

(2) FIG. 2. Illustrates a typical flowering stem from CHAMELEON ROSE grown in an unheated greenhouse in the Netherlands.

(3) This plant is approximately 250 days old, grown in the ground. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

(4) In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe CHAMELEON ROSE plants grown in the ground in an unheated greenhouse in Angeren, the Netherlands. The plants were about 250 days old. Temperatures ranged from-6 C. to 15 C. at night to 5 C. to 30 C. during the day. No chemical treatments were given to the plants, only biological control for thrips. Measurements and numerical values represent averages of typical plant types. Botanical classification: Campanula medium CHAMELEON ROSE.
