Abstract

A new Ageratum plant, characterized particularly as to novelty by light purple red flowers, early and continuously flowering and has a growing habit that is flat, well branched and vigorous.

Description

Latin name of the genus and species of the plant claimed: Ageratum houstonianum.
Varietal denomination: ‘Agrosamtis’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new distinct cultivar of Ageratum, botanically known as Ageratum houstonianum.
The new variety “Agrosamtis” was discovered as a seedling variant of a population of rose and pink flowering plants in a controlled planting.
As a result of this the present cultivar was created in 2000 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Gilroy, USA, in Angers, France 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 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 US, only in zones 9 and 10 it is a perennial plant.
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 history was taken on 30 weeks old plants, blossomed under natural light in a greenhouse.
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.
