USPP35704P3 - Geranium plant named ‘MACGER002’ - Google Patents

Abstract

‘MACGER002’ is a new and distinctive variety of Geranium maculatum plant which is characterized by long-lasting, dark brown foliage and dark pink flowers with small white floral eye. The new variety propagates successfully by stem cuttings and tissue culture and has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Geranium maculatum L.

Variety denomination: The inventive variety of Geranium disclosed herein has been given the variety denomination ‘MACGER002’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2022/1754, filed Jul. 21, 2022, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘MACGER002’ is the result of a controlled cross-pollination breeding program carried out by the inventors at their commercial nursery in Kirkcudbright, Scotland, in the summer of 2015. The inventors performed a controlled cross-pollination of the emasculated seed parent, an unnamed Geranium maculatum plant developed by the inventors (unpatented) with Geranium maculatum ‘Spring Purple’ (unpatented), the pollen parent. Said pollination was performed in an insect proof environment. Seed from the cross was harvested, then germinated, and the resulting seedlings were then grown to a mature size in a protected poly tunnel greenhouse. In May of 2016, the inventors selected the new Geranium cultivar for its vivid flower color and dark foliage. This new and distinctive cultivar was given the name ‘MACGER002’.

Asexual Reproduction: Asexual reproduction of ‘MACGER002’ was first accomplished in 2016 by way of vegetative division in Kirkcudbright, Scotland, and subsequently by way of meristematic tissue culture micro propagation at a laboratory in Heerhugowaard, the Netherlands. Four successive generations have shown that the unique features of the instant cultivar are stable and reproduce true to type.

SUMMARY OF THE INVENTION

The cultivar ‘MACGER002’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Geranium cultivar, ‘MACGER002’.

• • 1. Geranium ‘MACGER002’ exhibits an abundance of long-lasting dark brown foliage; and
  • 2. Geranium ‘MACGER002’ exhibits foliage that is deeply cleft; and
  • 3. Geranium ‘MACGER002’ exhibits violet-purple flowers, generally appearing dark pink, with a small white floral eye.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Geranium plant known as ‘MACGER002’, based upon observations of 12-month-old plants grown in 17 cm nursery containers in Kirkcudbright, Scotland. Plants were grown in a vented, unheated greenhouse with partial shade exposure. Plants were manually watered as needed and fertilized with a slow-release granular fertilizer which was incorporated into the growing media. No chemical pest treatments were given to the plants. Observation data was recorded in May of 2022.
