Carnation named Digisun

Abstract

A new standard carnation cultivar particularly distinguished by its very large, light yellow colored flowers of a shade between Dresden Yellow and Sulphur Yellow, the flower petals being striated with very thin stripes of a medium Neyron Rose color giving the bloom a very distinctive appearance. The blooms are carried on strong, upright and rigid stems averaging about 90 cm. in length of a plant having moderately abundant foliage and standing at an average height of about 104 cm. at eight months. This plant blooms profusely, at recurrent intervals, in the Spring, Midseason and Fall blooming seasons, and on the plant, the flowers hang on and dry. As cut flowers, the lasting quality is at least ten days in vase keeping which, together with the other favorable characteristics of this new variety, provides a plant of very favorable marketing advantages.

Description

BACKGROUND OF THE NEW PLANT

Our new carnation cultivar originated as a seedling of a hybrid developed by us in our nursery in San Remo, Italy, where we do business under the name Azienda Agricola Di Giorgia Antonio E. Renate, the said hybrid resulting from our crossing two carnation varieties selected from our collection of carnation varieties identified and maintained at our nursery for breeding purposes. The present seedling was selected from among a group resulting from planting seeds of the before mentioned hybrid and this selected seedling was propagated by us and under our direction at our San Remo nursery by means of cuttings with such satisfactory results that propagation of this new plant was carried on through several successive generations at San Remo, which proved conclusively that the novel characteristics of this new plant would be retained from generation to generation and thus homogeneity could be assured.

The plant is now being propagated on a commercial scale at Establissements Barberet et Blanc, Laboratoire de Physiologie Vegetale, 83250 La Londe-Les Maures, France.

DESCRIPTION OF THE DRAWING

Our new carnation cultivar is illustrated by the accompanying photographic drawing, which shows several stems of the plant with buds and blooms in several stages of development, the color rendition being as nearly true as is reasonably possible to obtain by professional photographic procedures.
