Regal pelargonium `315-(83-48-1)`

Abstract

This invention relates to a new and distinct cultivar of regal Pelargonium (Pelargonium.times.domesticum) named `Splendor` substantially as illustrated and described herein, particularly characterized as being compact and self-branching, early flowering and floriferous, and having bright salmon pink flowers with ruby feathering on the upper petals.

Description

The present invention relates to a new and distinct cultivar of regal Pelargonium (Pelargonium.times.domesticum) called `Splendor`. This cultivar is characterized as being compact and self-branching (without pinching), early flowering and floriferous. The ruffled flowers are bright salmon pink with ruby feathering on the upper petals.

The cultivar was developed from an organized, scientifically designed breeding program conducted at the Department of Horticulture, The Pennsylvania State University, University Park, Pa. 16802. The objective was to produce a new regal pelargonium genotype with excellent propagation characteristics, compact growth habit, predictable and consistent flowering response, and acceptable postharvest quality. The pedigree of this cultivar is as follows: ##STR1##

`Splensor` includes the cultivars `Virginia` and `Grand Slam` in its ancestry. It resembles but is much lighter than `Virginia` in its flower color; however, it is a smaller, more compact plant with improved branching characteristics and it flowers earlier under low irradiance conditions. `Splendor` produces twice as many flowers as `Grand Slam` and is much more amenable to flowering under warm temperature conditions.

The selection was asexually propagated by cuttings and the reproductions ran true.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates in color the cultivar including foliage and flowers.

FIG. 2 illustrates in color primarily the floret.

With reference to the detailed description of the cultivar which follows, the test plant was potted in soilless medium and grown in a glasshouse under natural sunlight, at a night temperature of approximately 58.degree. F. and a day temperature of approximately 68.degree. F. Fertilizer was applied in every watering with 200 ppm nitrogen provided in the forms of 15-16-17 (two consecutive waterings) and 20-0-20 (every third watering) in a repeating cycle.

Color readings were taken under daylight fluorescent light at approximately 200 foot candles and color identification was by reference to the Royal Horticultural Society Colour Charts, except where common terms of color definition are employed.
