Geranium plant named ‘Pink Penny’

Abstract

A new cultivar of Geranium wallichianum, ‘Pink Penny’, characterized by its abundant, large pink flowers, its long blooming season, its marbled green foliage, and its spreading growth habit with good performance as a groundcover.

Description

Botanical classification: Geranium wallichianum.

Cultivar designation: ‘Pink Penny’.

BACKGROUND OF THE INVENTION

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

The inventor discovered the new cultivar, ‘Pink Penny’, in a cultivated growing area at his nursery in Warmond, The Netherlands in July of 2002. ‘Pink Penny’ was discovered as a whole plant mutation from repeated selections of seedlings that originated from seeds of unnamed pink flowering plants of Geranium wallichianum.

The new cultivar, ‘Pink Penny’, was selected as unique for its abundant large pink flowers and its long blooming habit. ‘Pink Penny’ can be most closely compared to Geranium wallichianum ‘Buxton's Variety’ (not patented) for its long blooming habit. ‘Buxton's Variety’ differs in particular in having blue flowers, whereas ‘Pink Penny’ blooms with pink flowers.

Asexual reproduction of the new cultivar was first accomplished by division in Warmond, The Netherlands in 2003 by the inventor. Propagation by division and subsequently by tissue culture 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 ‘Pink Penny’. These attributes in combination distinguish ‘Pink Penny’ as a new and distinct cultivar of Geranium.

• • 1. ‘Pink Penny’ has large flowers with an average diameter of 3.5 cm.
  • 2. The flower color of ‘Pink Penny’ is pink with dark purple veining.
  • 3. ‘Pink Penny’ blooms abundantly with a long blooming season; blooming from mid May to late September in The Netherlands.
  • 4. The foliage of ‘Pink Penny’ is medium green in color with lighter green marbling.
  • 5. The plant habit of ‘Pink Penny’ is prostrate with suitable use as a groundcover.
  • 6. ‘Pink Penny’ propagated with easy by division or tissue culture.
  • 7. Cold hardy to at least USDA Zone 5.
