plant named ‘Midnight Clouds’

Abstract

A new cultivar of Geranium, ‘Midnight Clouds’, characterized by its large, sturdy, dark purple-green leaves, its white-light pink flowers held on sturdy red stems, its long blooming season, and its resistance to powdery mildew.

Description

Botanical classification: Geranium hybrid.

Cultivar designation: ‘Midnight Clouds’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically of hybrid origin and known as Geranium ‘Midnight Clouds’ and will be referred to hereafter by its cultivar name, ‘Midnight Clouds’.

The inventor discovered the new cultivar, ‘Midnight Clouds’, a naturally occurring whole plant mutation in his garden in Hillegom, The Netherlands in June of 2008. The parentage of ‘Midnight Clouds’ is unknown, however it is likely to be a hybrid between Geranium pratense and Geranium maculatum based on its characteristics and their proximity in the garden in which ‘Midnight Clouds’ was discovered.

Asexual reproduction of the new cultivar was first accomplished by tissue culture under the direction of the Inventor in Rijswijk, The Netherlands in 2009. Propagation 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 ‘Midnight Clouds’. These attributes in combination distinguish ‘Midnight Clouds’ as a new and distinct cultivar of Geranium.

• • 1. ‘Midnight Clouds’ exhibits foliage that is dark purple-green in color.
  • 2. ‘Midnight Clouds’ exhibits leaves that are large and sturdy.
  • 3. ‘Midnight Clouds’ exhibits white-light pink flowers held on sturdy red stems.
  • 4. ‘Midnight Clouds’ exhibits a long blooming season; blooming from May to September in The Netherlands.
  • 5. ‘Midnight Clouds’ has been observed to be resistant to powdery mildew.

‘Midnight Clouds’ differs from cultivars of its likely parent species in having larger and stronger leaves. ‘Midnight Clouds’ can be most closely compared to ‘Midnight Reiter’ (not patented). ‘Midnight Clouds’ differs from ‘Midnight Reiter’ in having larger and stronger leaves, in having greater resistance to powdery mildew and in having white-light pink flowers rather than lavender-blue. ‘Midnight Clouds’ can also be compared to ‘Hocus Pocus’ (not patented). ‘Hocus Pocus’ differs from ‘Midnight Clouds’ in having a more compact mounded plant habit and in having light purple 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 a one year-old plant of ‘Midnight Clouds’ as grown outdoors in a one-gallon container in Noordwijk, The Netherlands.

The photograph in FIG. 1 is a view of a plant of ‘Midnight Clouds’ in bloom.

The photograph in FIG. 2 is of a close-up view of a leaf of ‘Midnight Clouds’ while the photograph in FIG. 3 provides a close-up view of the flowers of close-up view of ‘Midnight Clouds’. The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description more accurately describe the colors of the new Geranium.
