Carnation named Hilswiss

Abstract

A new spray carnation variety particularly distinguished by its continuous and profuse production of relatively small flowers having basically white petals characterized by currrant red picotee at the petal margins and a few marginal stripes of the same color which cause the bloom to have a very attractive rosy appearance, the blooms being borne on erect, rigid stems of about 60 cm. in length, there being more than three flowers per stem. The plant has a strong, vigorous and upright growth habit with abundant foliage, a rapid growth habit and a total height of approximately 100 cm.

Description

BACKGROUND OF THE NEW PLANT

This new spray carnation cultivar originated as a seedling of a hybrid resulting from my crossing of two unnamed and unpatented carnation varieties selected from my collection of carnation plants maintained by me for breeding purposes at my nursery in Aalsmeer, The Netherlands, the object of this crossing being to improve the range of varieties for commercial production of plants having more rapid growth, better flower colors and improved production rate. This particular seedling was selected by me for propagation because of the almost pure white general coloration of its flower petals characterized by red picotee at all petal margins and occasional inwardly-extending red marginal stripes and propagation was done by me at Aalsmeer by means of cuttings with such satisfactory results that this new carnation variety was propagated under my direction at Aalsmeer for several successive generations by means of cuttings, which clearly demonstrated that the new plant would maintain its distinctive characteristics from generation to generation and that its homogenetic character could be assured for commercial production.

DESCRIPTION OF THE DRAWING

My new spray carnation variety is illustrated by the accompanying photographic drawing which shows, in full color, a flower stem having blooms and buds in several stages of maturity, as well as a face view of the flower, several petals and a bud at the beginning of its opening stage, the colors shown being as nearly true as is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT

Sepals:

Number.--Five or six.

Size.--Average.

Shape.--Generally ovate with an acute tip.

Character.--The sepals are hooded over the bud before dividing and stand up as the flower petals unfurl.

THE FRUIT

Fertility: The fruit is fertile.

Shape: Lozenge-shaped.

Color at maturity: Wellow/brown.

This spray carnation most nearly resembles the variety `Fashion` (unpatented). The new variety is distinguished from `Fashion`, however, because the base color of the petals is white instead of cream yellow, the foliage color is somewhat greener and the plant has a more rapid growth rate.

Claims

1. The new and distinct spray carnation variety, substantially as herein shown and described, characterized by its relatively small flowers having basically white petals, red picotee along its marginal edges and red marginal stripes, its continuous and profuse blooming habit with the flowers carried on a long flower stem, and its vigorous and upright growth habit with abundant foliage.
