plant named ‘Flower Power’

Abstract

A new and distinct variety of Leucanthemum superbum plant as shown and described, characterized by white ray florets and yellow disc florets on upright branched stems and a medium to large height.

Description

Latin name: Leucanthemum superbum.

Cultivar name: ‘Flower Power’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of Leucanthemum superbum plant named ‘Flower Power’ characterized by white ray florets and yellow disc florets on upright branched stems and a medium to large height.

The new Leucanthemum superbum was raised as an open pollinated seedling from a controlled breeding program, the seed was sown as Leucanthemum superbum ‘Hebron Hardy’ not patented, at a nursery in Hebron, Ill. in 2015. The selection of the new plant was due to its white ray florets and yellow disc florets on upright branched stems and a medium to large height.

Asexual division, and cutting propagation have been the means of reproduction. Propagation has taken place at a nursery in Hebron, Ill. since 2016. The new Leucanthemum has shown to be stable and identical in reproduction after rooting over 2000 plants from 2016 to 2022. No plants of the new Leucanthemum superbum have been sold in this country, or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which was disclosed by the inventor and his company, Intrinsic Perennial Gardens, Inc within one year of filing of this application and was derived directly from the inventor, including the company Garden Choice offering of the plant.

SUMMARY OF THE INVENTION

The new Leucanthemum superbum plant named ‘Flower Power’ characterized by white ray florets and yellow disc florets upright branched stems and a medium to large height have been observed to be unique and stable.

Plants of the new Leucanthemum can be compared to plants of Leucanthemum superbum ‘Becky’ not patented. 1. The new Leucanthemum superbum plant has a mature size measuring 60-75 cm high and 65-85 cm wide while Leucanthemum superbum ‘Becky’ measures 100-120 cm high and over 100 cm wide. 2. The new Leucanthemum superbum plant has an upright branched habit while Leucanthemum superbum ‘Becky’ has an open habit. 3. The new Leucanthemum superbum plant has smaller foliage approximately 30 mm wide while Leucanthemum superbum ‘Becky’ has foliage that reaches approximately 35 mm wide.

Plants of the new Leucanthemum superbum can also be compared to the seed parent plant Leucanthemum superbum ‘Hebron Hardy’ not patented. 1. The new plant has a uniform height since it is produced asexually from vegetative division and cutting propagation while the seed parent is produced from seed and the height and plant size varies.

Plants of the new Leucanthemum superbum can also be compared to plants of Leucanthemum superbum ‘Banana Cream’, U.S. Plant Pat. No. 23,181. 1. The new plant inflorescence color is white ray florets and yellow disc florets while the inflorescence color of the Leucanthemum superbum ‘Banana Cream’ plant is yellow ray florets and yellow disc florets.
