plant named ‘MACGEU050’

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein isspecies.

Variety denomination: The inventive variety ofhybrid disclosed herein has been given the variety denomination ‘MACGEU050’.

This application claims priority to the Community Plant Variety Rights application number 2023/1680, filed Aug. 15, 2023, which is herein incorporated by reference.

Parentage: ‘MACGEU050’ is the result of a controlled cross-pollination breeding program carried out by the inventors at their commercial nursery in Kirkcudbright, Scotland, in 2015 and 2016. The inventors performed a controlled cross-pollination of the emasculated seed parent,‘Lady Strathedon’ (unpatented), with an unnamed, yellow-floweredsp. plant. The unnamed pollen parent was developed and is owned by the inventor and was never made available to the public. 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 2018, the inventors selected the newcultivar for its unique flower and bloom characteristics. This new and distinctive cultivar was given the name ‘MACGEU050’.

Asexual Reproduction: Asexual reproduction of ‘MACGEU050’ was first accomplished in 2019 by way of meristematic tissue culture micro propagation at a laboratory in Rijswijk, the Netherlands. Three successive generations have shown that the unique features of the instant cultivar are stable and reproduce true to type.

The cultivar ‘MACGEU050’ 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 newcultivar, ‘MACGEU050’.

The following is a detailed botanical description of a new and distinct variety ofknown as ‘MACGEU050’, based upon observations of 3-month-old greenhouse-grown plants grown in Kirkcudbright, Scotland. Plants were grown using conventional greenhouse production protocols forplants 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 July of 2024.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘MACGEU050’ 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, London, 2007 edition.

A botanical description of ‘MACGEU050’ and comparisons with the seed parent and most similar variety of common knowledge are provided below.

Plants of the new cultivar ‘MACGEU050’ differ from its seed parent,‘Lady Strathedon’ (unpatented), by the characteristics described in Table 1. The pollen parent is no longer available for comparison.

Plants of the new cultivar ‘MACGEU050’ may be distinguished from the most similar known commercial comparator,‘Lisanne’ (not patented), by the characteristics described in Table 2.
