plant named ‘MACGEU001’

‘MACGEU001’ is a new and distinctive variety of Geum hybrid which is characterized by large, semi-double flowers which are scarlet red in color and suffused with peachy-orange tones, tall flowering stems, and a long bloom period. 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 Geum L.

Variety denomination: The inventive variety of Geum hybrid disclosed herein has been given the variety denomination ‘MACGEU001’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geum hybrid, which has been given the variety denomination of ‘MACGEU001’. Its market class is PLT/263.1.

Parentage: ‘MACGEU001’ is the result of a controlled cross-pollination breeding program carried out by the inventors at their commercial nursery in Kirkcudbright, Scotland, in 2012. The inventors performed a controlled cross-pollination of the emasculated seed parent, Geum hybrid ‘Beech House Apricot’ (unpatented), with the pollen parent, Geum chiloense ‘Red Dragon’ (unpatented). Said pollination was performed in an insect proof environment. Seed from said cross was harvested, then germinated, and the resulting seedlings were then grown to a mature size in a protected poly tunnel greenhouse. In 2014, the inventors selected the new Geum cultivar for its unique flower and bloom characteristics. This new and distinctive cultivar was given the name ‘MACGEU001’.

Asexual Reproduction: Asexual reproduction of ‘MACGEU001’ was first accomplished in 2014 by way of meristematic tissue culture micro propagation at a laboratory in Rijswijk, the Netherlands. 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 ‘MACGEU001’ 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 Geum cultivar, ‘MACGEU001’.

    • 1. Geum ‘MACGEU001’ exhibits large, semi-double flowers; and
    • 2. Geum ‘MACGEU001’ exhibits unique scarlet red flowers suffused with peachy-orange tones; and
    • 3. Geum ‘MACGEU001’ exhibits long flowering stems; and
    • 4. Geum ‘MACGEU001’ exhibits a long bloom period, from April to September in Kirkcudbright, Scotland.

 BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Geum known as ‘MACGEU001’, based upon observations of 3 month old greenhouse-grown plants grown in Kirkcudbright, Scotland. Plants were grown using conventional greenhouse production protocols for Geum plants including regular overhead irrigation, fertigation feeding, and full sun to partial shade exposure. With the exception of chemical control for thrips insects, no other chemical treatments were given to the plants. Observation data was recorded in May of 2016.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘MACGEU001’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2007 edition.

A botanical description of ‘MACGEU001’ and comparisons with the parents and most similar variety of common knowledge are provided below.
