Botanical classification: Pelargonium×hortorum.
Varietal denomination: ‘Maestro White Splash’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Pelargonium×hortorum known by the varietal name ‘Maestro White Splash’. The new variety was discovered in Lompoc, Calif. The new variety is a result of cross breeding ‘Americana White Splash’ (female parent) (U.S. Plant Pat. No. 9,317) and ‘Patriot Light Pink’ (male parent) (U.S. Plant Pat. No. 10,484). The purpose of the breeding program was to introduce a compact geranium more suitable for tight greenhouse spacing. The new variety is similar in flower color to its female parent, but has a more compact and spreading habit with early flowering. The new variety exhibits a different flower color than its male parent. ‘Maestro White Splash’ is also more free and early flowering with a compact habit and has good repeat blooming when compared to other varieties known to the breeder. The new variety was first asexually reproduced by cuttings in Connellsville, Pa. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.
The new variety was grown in a 4″ pot with fertilizer at 200 ppm nitrogen. The new variety exhibits developed roots at 17 days at an average temperature of 21° C. and has a response time of seven weeks from a rooted cutting to flowering in a 10 cm. container.
DESCRIPTION OF THE DRAWING
The accompanying photographic drawing illustrates the new variety, with the color being as nearly true as is possible with color illustrations of this type.
DESCRIPTION OF THE PLANT
The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out in Connellsville, Pa. The color readings were taken indoors under 200-220 foot candles of cool white fluorescent light. The new variety was eight weeks from a rooted cutting when described. Color references are primarily to the 1966 R.H.S Colour Chart of The Royal Horticultural Society of London.

INFLORESCENCE
- Bud:
- Stage of development when bud characteristics determined.—One floret just opening at sepal tips.
- Shape of cluster.—Oval — ellipse.
- Diameter of cluster.—2.3-2.4 cm.
- Number of buds per cluster.—16-20 (more present as the plant matures).
- Shape of individual bud.—Ellipse — pointed at apex.
- Length of individual bud.—Just prior to opening: 0.9-1.0 cm.
- Width of individual bud.—0.6-0.65 cm.
- Color note.—As bud pushes beyond sepals and prepares to open, the petal's exposed surface appears to be Orange-White Group 159C and the upper petal surface appears to be Red-Purple Group 62C-D.
- Natural flowering season at specified location(s): Forced in a greenhouse, so there is no specific season.
- Blooming habit: Continuous and free-flowering.
- Umbel diameter of a mature flower: 10 cm.
- Umbel depth: 5.8-5.9 cm.
- Borne: Umbel, flowers on pedicel, pedicel on peduncle. Also, the three lower petals are grouped together and then there is a space and two upper petals.

- Petals: Color: Upper surface: White with a blush pink tint. The closest white is White Group 155D. There is an illusion of tint to resemble a pale Red-Purple Group 69C. The veins from base to eye are Red-Purple Group 64A. The blotch (eye) covers the width of the petal at the base prior to narrowing for attachment. It then tapers to a central point just under half of the length of the petal. The blotch (eye) is smaller on lower petals and Red-Purple Group 66B. The lower petals do not have blotch extending the width of the petal base. Near the edge of the blotch, the color resembles Red-Purple Group 63B. Older flowers have less blush. The lower petals have no veining. Lower surface: The upper and lower petals are White Group 155D. The upper petals have veining from the base to ½ distance of the petal. The vein is Red-Purple Group 67A at its darkest point and is overcome by white to resemble Red-Purple Group 68C & D.
