Ageratum plant named ‘Agpatbicpuli’

Abstract

A new Ageratum plant named ‘Agpatbicpuli’ characterized by its large, deep violet flowers, early flowering, strongly branched plant habit and vigorous growth.

Description

Latin name of the genus and species of the plant claimed: Ageratum houstonianum.

Varietal denomination: ‘Agpatbicpuli’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Ageratum, botanically known as Ageratum houstonianum.

The new cultivar is propagated from cuttings resulting from the cross of ‘W 73-2’ as female parent and ‘Agmontis’ as male parent. This cross was made in September 2001. ‘W 73-2’ is not commercially available and is not patented. ‘Agmontis’ is commercially available and is patented as U.S. Plant Pat. No. 15,301.

As a result of this cross the present cultivar was selected in September 2002 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands. The present cultivar was tested in Enkhuizen, Netherlands, in Gilroy, USA, and in Sarrians, France over a three year period. The distinctive characteristics of this new Ageratum are stable and reproduced true to type in successive generations of asexual reproduction. It takes 6 to 8 weeks to produce a finished plant, depending on the temperature.

This new Ageratum plant is an annual in most climatical zones in the US, only in zones 9 and 10 it is a perennial plant.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Agpatbicpuli.’ These characteristics in combination distinguish ‘Agpatbicpuli’ as a new and distinct Ageratum cultivar:

• • 1. Vigorous, upright and mounded growth habit
  • 2. Freely branching habit
  • 3. Freely flowering habit with large capitula in compound umbels
  • 4. Large, deep violet capitula on green colored leaves

Plants of the new Ageratum differ primarily from the plants of the female parent selection in the following characteristics:

Plants of the new Ageratum have purple and violet bicolored capitula whereas plants of the female parent selection have purple capitula.

Plants of the new Ageratum differ primarily from the male plant selection in the following characteristics:

Plants of the new Ageratum have purple and violet bicolored capitula whereas plants of the female parent selection have purple capitula.

DESCRIPTION OF THE DRAWING

This new Ageratum plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Ageratum. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 20 week old plants, blossomed under natural light in the field.

Color readings were taken in the laboratory under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
