Geranium plant named ‘Free White’

Abstract

A geranium cultivar particularly distinguished by green foliage, white flower color, and semi-double flowers on large umbels, fast rooting and exhibits vigorous growth.

Description

GENUS AND SPECIES

Pelargonium hortorum.

VARIETY DENOMINATION

‘Free White’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium peltatum Bailey, and hereinafter referred to by the cultivar name ‘Free White’. The new cultivar is propagated from a seedling resulting from the cross of 7407-2 a white flowered, unnamed and unpatented proprietary line and 6745-3 a white flowered, unnamed and unpatented proprietary line.

‘Free White’ is a product of a planned breeding program intended to create new geranium cultivars with white colored flowers, semi-double flower form, green foliage, vigorous growth and superior cutting productivity.

The new cultivar was created in 1997 in Gilroy, Calif. and has been repeatedly asexually reproduced by cuttings in Gilroy, Calif. and Guatemala over a two and a half year period. It has also been trialed at Gilroy, Calif. and Andijk, The Netherlands. It has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

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

FIG. 1 shows overall plant habit.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Free White’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on five month old plants grown in 8 inch pots, blossomed under natural light in a greenhouse and color readings were taken in the greenhouse in Gilroy, Calif. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.).
