Geranium plant named ‘Sweet Heidy’

Abstract

A new cultivar of Geranium wallichianum, ‘Sweet Heidy’, characterized by its abundant, tricolor flowers with purple veins; pale violet centers become purple pink in the middle regions and violet-blue near the margin, its long blooming season, its clean foliage with yellow spots, its prostrate spreading growth habit with good performance as a groundcover and its cold hardiness at least to U.S.D.A. Zone 5.

Description

Botanical classification: Geranium wallichianum.

Cultivar designation: ‘Sweet Heidy’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Geranium wallichianum ‘Sweet Heidy’ and will be referred to hereafter by its cultivar name, ‘Sweet Heidy’.

‘Sweet Heidy’ was derived from a breeding project in Warmond, The Netherlands. The inventor's goal was to develop new cultivars of Geranium wallichianum that are long blooming, free of disease, and exhibit unique flower coloration. ‘Sweet Heidy’ was selected as a single plant from among the seedlings that resulted from crosses made in 2002 between unnamed pink and blue flowering plants of Geranium wallichianum.

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation under the direction of the inventor in Roelofsarensveen, The Netherlands in fall of 2004. Propagation by tissue culture and division has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of ‘Sweet Heidy’. These attributes in combination distinguish ‘Sweet Heidy’ as a new and distinct cultivar of Geranium.

• • 1. ‘Sweet Heidy’ exhibits flowers that are tri-color with purple veins; pale violet centers become purple pink in the middle regions and violet-blue near the margin.
  • 2. ‘Sweet Heidy’ is long blooming; flowers from May until frost in The Netherlands.
  • 3. ‘Sweet Heidy’ produces an abundance of flowers continuously through the bloom season.
  • 4. ‘Sweet Heidy’ has clean green foliage with yellow spots (enlarged vein areas).
  • 5. ‘Sweet Heidy’ has a prostrate growth habit with suitable use as a groundcover.
  • 6. ‘Sweet Heidy’ is propagated with ease by division or tissue culture.
  • 7. ‘Sweet Heidy’ is cold hardy at least to U.S.D.A.9 Zone 5.

The new cultivar, ‘Sweet Heidy’, is unique from the all other cultivars of Geranium wallichianum known to the inventor and is particularly unique for its tri-colored flowers. ‘Sweet Heidy’, can be compared to Geranium wallichianum cultivars ‘Buxton's Variety’ (not patented) and ‘Pink Penny’ (U.S. Plant Pat. No. 17,656), both similar in having a long blooming habit. ‘Buxton's Variety’ differs in particular in having blue flowers while ‘Pink Penny’ exhibits pink flowers.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Geranium. The photographs were taken of three year-old plants of ‘Sweet Heidy’ as grown outdoors in a two-gallon container in The Netherlands.

The photograph in FIG. 1 is a side view of a plant of ‘Sweet Heidy’ in bloom in fall.

The photograph in FIG. 2 is of a close-up view of a flower of ‘Sweet Heidy’ and the photograph in FIG. 3 provides a close-up view of a leaf of ‘Sweet Heidy’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Geranium.
