| Abstract: |
A new Ageratum plant, characterized particularly as to novelty by large light violet blue flowers, early flowering, freely branching plant habit and vigorous growth. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of Ageratum houstonianum plant named `Agalib,` as substantially illustrated and described herein. |
| Description: |
Latin name of the genus and species of the plant claimed: Ageratum houstonianum.
Varietal denomination: `Agalib`.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new distinct cultivar of Ageratum, botanically known as Ageratum houstonianum. The new cultivar is propagated from cuttings resulting from the cross in October 1999 of `U 43-2` as female parent and `T393-3` asmale parent. `U 43-2` is not commercially available and has not been patented. `T393-3` is not commercially available and has not been patented.
As a result of this cross, present cultivar was created in August 2000 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Gilroy, Calif., and in Sarrians, France over a three-yearperiod. The distinctive characteristics of this new Ageratum are stable and reproduced true to type in successive generations of asexual reproduction. It takes 8 to 10 weeks to produce a finished plant, depending on the temperature.
This new Ageratum plant is an annual in most climatical zones in the U.S., 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 characterists of `Agalib`. These characteristics in combination distinguish `Agalib` as a new and distinct Ageratum cultivar: 1. Vigorous, upright andmounded growth habit. 2. Freely branching habit. 3. Freely flowering habit with large capitula in compound umbels. 4. Light violet blue capitula on green coloured 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 light violet blue coloured capitula whereas plants of the female parent selection have white and blue capitula. Plants of the new Ageratum have a good branching habit, whereas the plants of the female parent havea less branching habit.
Plants of the new Ageratum differ primarily from the male plant selection in the following characteristics:
Plants of the new Ageratum have light violet blue coloured capitula whereas plants of the male parent selection have white capitula. Plants of the new Ageratum have a vigorous habit with large leaves, whereas the plants of the male parent have acompact habit.
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 shown 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 historywas taken on 20 weeks old plants, blossomed under natural light in the field.
Color readings were taken in the greenhouse under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
