Chrysanthemum plant named ‘Orange Urano’

Abstract

A new plant variety of chrysanthemum producing flowers with orange ray florets.

Description

BACKGROUND OF THE INVENTION

The present invention is directed to a new and distinct variety of Chrysanthemum morifolium. The varietal denomination of the new chrysanthemum is ‘ORANGE URANO’.

The new variety was discovered as a single branch mutation of ‘Red Urano’. The new variety has been asexually reproduced by vegetative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

‘ORANGE URANO’ is a chrysanthemum plant that produces flowers with orange ray florets.

COMPARISION WITH PARENTS

‘ORANGE URANO’ differs from its parent in having different color florets.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying photograph shows a typical specimen of the plant and flowers of the new variety with colors being as nearly true as possible with illustrations of this type.

DESCRIPTION OF THE PLANT

The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif. Plants described are approximately 95 days old from a rooted cutting. ‘ORANGE URANO’ has not been observed under all possible environmental conditions. The phenotype may vary with variations in the environment such as temperature, light intensity, day length and cultural conditions. The color designations herein are from The Royal Horticultural Society Colour Chart except where general terms are used.

To produce a commercial product the plants may be pinched once about ten days after planting. No growth retardant has been applied in the specimens described. Useful growing conditions include average night temperatures of about 17° C. to 20° C. and average day temperatures of about 20° C. to 30° C. No susceptibility or resistance to disease has been observed. Resistance or susceptibility to insects has not been observed. Seed production has not been observed. Winter hardiness and drought/heat tolerance have not been observed.
