Germanium plant named `Sanwhite`

Abstract

A new ivy-leaved geranium particularly distinguished by its well-branched shape and compact growth, early appearing blush white single flowers which do not set seed with good precocity and floral richness.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of ivy-leaved geranium, botanically known as Pelargonium peltatum hybrid. The new cultivar is propagated from cuttings resulting from the cross of G53 and I229. G53 is a blush white flowering peltatum having no pollen. G53 is not commercially available and is not known by any synonyms. I229 is also a white colored peltatum, with vigorous growth and having pollen. I229 is not commercially available and is not known by any synonyms. Neither G53 nor I229 have been patented. As a result of this cross the present cultivar was created in 1990 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Stuttgart, Germany over a four year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed.

DESCRIPTION OF THE DRAWING

This new geranium plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new geranium. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 12 week old plants, blossomed under natural light in a greenhouse. Color readings were taken in the greenhouse under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticulture Society of London.

Strength.--Very strong, the florets are arranged asymmetric around the middle of the cluster. The florets are approximately 30 mm in diameter.

Color.--138A.

THE FLOWER

Blooming habit: Continuous and profusely from April until October.

Size: Approximately 50-60 mm.

Borne: In a cluster having between 4-8 flowers per cluster.

Form: Horizontal symmetric, quite open. When the flowers mature, the petals curl back.

Petals:

Numbers.--5 per floret, between 100-120 clusters in one season per plant.

Arrangement.--2 upper petals, longer and broader. 3 lower petals, smaller.

Form.--Obcordate.

Color.--Outer petal -- 65C, very light pink. Inside petal -- White (lower) or red purple (upper).

Markings.--See pattern.

Reverse side.--White with pink nerves color 56B.

Pattern.--The upper two petals have two long red-purple margins (color 59C) which fade into the veins. Between the two lines thereis a small pink blotch. The reverse side has the same stripes, but lighter in color. The lower petals have very small (2mm) pink lines, mostly 2. The outer parts of the petals are very light pink colored.

Texture.--Smooth.

Appearance.--Satiny. Petals remain on stem about 5-7 days depending on the weather.

Persistence: Petals drop, so no picking of matured clusters.
