Title: Carnation named Hilbar

Description:
BACKGROUND OF THE NEW PLANT 
     My new carnation cultivar originated as a seedling of unnamed parentage growing among a collection of carnations maintained particularly for breeding purposes at a commercial nursery at Aalsmeer, Holland. The crossing which produced this new plant was made by me in about 1979 with the object of developing new and better carnation varieties having a higher yield and improved quality. This new plant was discovered by me in about 1980 and selected for propagation and test because of its apparently rapid growth rate and its production of many very attractive button-sized blooms which appeared to be produced profusely. I propagated this plant by means of cuttings at Aalsmeer with such favorable results that I continued that kind of propagation through several successive generations, which demonstrated that its advantageous and novel characteristics would hold true from generation to generation and appeared to be firmly fixed. 
    
    
     DESCRIPTION OF THE DRAWING 
     My new variety of spray carnation is illustrated by the accompanying photographic drawing which shows, in full color, the upper portion of a typical spray stem bearing buds in various stages, together with fully opened flowers, the drawing also including a face view of a single fully opened flower and parts of a half opened bud to show the petal characteristics, the colors shown being as nearly true as it is reasonably possible to obtain by conventional photographic procedures. 
    
    
     DESCRIPTION OF THE NEW PLANT

Colour Chart published by The Royal Horticultural Society of London, England.
