Abstract

A new cultivar of Chrysanthemum plant named ‘Lexy’ that is characterized by orange pompon flowers with a dark center, a strong and uniform stem, dark green leaves, good life as a cut flower and a large quantity of flowers at the top of the plant. In combination, these traits set ‘Lexy’ apart from other known existing varieties of Chrysanthemum.

Description

Botanical classification: Chrysanthemum Dendranthema Indicum.
Variety denomination: ‘Lexy’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant botanically known as Chrysanthemum Dendranthema Indicum and hereinafter referred to by the cultivar name ‘Lexy’.
The new cultivar is the product of a breeding program conducted by the inventor in a cultivated area of De Lier, The Netherlands. The objective of the breeding program is to develop new Chrysanthemum cultivars with interesting and unique flower colors and shapes that are suitable for high volume greenhouse production.
‘Lexy’ is a hybrid that originated from the induced hydribization of the female or seed parent Chrysanthemum ‘Restone’ (not patented) and the male or pollen parent Chrysanthemum ‘Ariane’ (not patented). The cultivar ‘Lexy’ was selected by the inventor in May of 2001 as a single plant within the progeny of the stated cross in a controlled environment of De Lier, The Netherlands.
Asexual reproduction by terminal cuttings of the new cultivar ‘Lexy’ were performed in August 2001 in De Lier, The Netherlands. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The following represent the distinguishing characteristics of the new Chrysanthemum cultivar ‘Lexy’. These traits in combination distinguish ‘Lexy’ as a new and distinct cultivar apart from other known varieties of Chrysanthemum.
    • 1. Chrysanthemum ‘Lexy’ exhibits an orange pompon flower with a dark center.
    • 2. Chrysanthemum ‘Lexy’ exhibits a strong and uniform stem.
    • 3. Chrysanthemum ‘Lexy’ exhibits dark green leaves.
    • 4. Chrysanthemum ‘Lexy’ exhibits good life as a cut flower.
    • 5. Chrysanthemum ‘Lexy’ exhibits a large quantity of flowers on the top.
    • 6. Chrysanthemum ‘Lexy’ exhibits a short crop time.
The closest comparison varieties are Chrysanthemum ‘Deliflame’ (not patented) and Chrysanthemum ‘Baltimore’ (not patented). ‘Lexy’ is different than ‘Deliflame’ in that ‘Lexy’ has a longer response time, smaller flowers, a stronger more uniform stem and smaller leaves. ‘Lexy’ is different than ‘Baltimore’ in that ‘Lexy’ is not resistant to white rust, has smaller leaves and more uniform stems. The leaves of ‘Baltimore’ are susceptible to yellowing while the leaves of ‘Lexy’ are not. The flowers of ‘Baltimore’ are gold with a light center. The flowers of ‘Lexy’ are orange with a dark center.
‘Lexy’ is different than the female parent ‘Restone’ in that ‘Lexy’ has larger flowers, smaller leaves and more uniform stems. The leaves of ‘Restone’ are susceptible to yellowing while the leaves of ‘Lexy’ are not. The flowers of ‘Restone’ are gold with a light center. The flowers of ‘Lexy’ are orange with a dark center.
‘Lexy’ is different than the male parent ‘Ariane’ in that ‘Lexy’ has shorter more uniform stems and a longer response time. ‘Ariane’ is resistant to white rust while ‘Lexy’ is not. The flowers of ‘Ariane’ are pale pink with a dark center. The flowers of ‘Lexy’ are orange with a dark center.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photograph illustrates the distinguishing traits of Chrysanthemum ‘Lexy’. The plant in the photograph shows an overall view of a 10 week old plant. The photograph was 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 technique.
 BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of the new Chrysanthemum cultivar named ‘Lexy’. Data was collected in De Lier, The Netherlands from 10 week glass greenhouse grown plants. The time of year was June and the average temperature was 18.5° Centigrade during the day and night. The light level was natural outdoor light. Photoperiodic treatments of 2 weeks of long days and 8 weeks of short days were used. Alar growth retardant was used 4 times at a rate of 2 grams per liter. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used.
‘Lexy’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
