Americana Cherry Rose

Abstract

A new and distinctive Geranium cultivar particularly distinguished by its rose red colored semi-double flowers and its vigorous fast-rooting growth habit.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Geranium, botanically known as Pelargonium hortorum Bailey. The new cultivar is propagated from a seedling resulting from the cross of a breeding line with rose red semi-double flowers and a pollen parent breeding line with a purple red single flower.

This geranium cultivar is a product of a planned breeding program intended to create new Geranium cultivars with rose red colored flowers, semi-double flower form, green foliage, vigorous growth and superior cutting productivity.

The new cultivar was created in 1988 in Gilroy, Calif. and has been repeatedly asexually reproduced by cuttings in Gilroy, Calif. and Guatemala over a two year period. It has also been trialed at Okemos, Mich. 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 colors shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description set forth the distinctive characteristics of this geranium cultivar. The data which defines these characteristics were collected from asexual reproductions carried out by Goldsmith Seeds, Inc. in Gilroy, Calif. The plant history was taken on 36 week old plants, blossomed under natural light in a greenhouse and color readings were taken in the greenhouse on May 29, 1990 at 2:00 p.m. under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London, England.
