USPP37140P2 - Scirpus pendulus plant named ‘Stars and Stripes’ - Google Patents

Abstract

A new, distinct Scirpus pendulus plant as illustrated and described characterized by center variegated foliage RHS color 2 D giving the plant a showier foliar display to be unique and stable.

Description

Latin name: Scirpus pendulus.

Cultivar name: ‘Stars and Stripes’.

BACKGROUND OF THE INVENTION

The present invention relates to a new form of Scirpus pendulus plant named ‘Stars and Stripes’. ‘Stars and Stripes’ is a naturally occurring sport of an unnamed Scirpus pendulus, not patented, characterized by center variegated foliage. The new plant was found in a cultivated area at a wholesale perennial nursery in Leland, IL in 2019. The selection of this plant was due to center variegated foliage giving the plant a showier foliar display. Asexual, vegetative division and tissue culture propagation have been the means of reproduction. Propagation has taken place at a nursery in Hebron, IL since 2020. In 2024 we planted 500 plants in pots. To date these plants have remained uniform in variegation. The new Scirpus pendulus has shown to be stable and identical in reproduction to the parent after making over 1000 vegetative divisions from 2020 to 2024. No plants of Scirpus pendulus ‘Stars and Stripes’ 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 within one year of the filing of this application and was either derived directly or indirectly from the inventor. Actual first date of sale was May 6, 2024.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (2001). The following traits have been repeatedly observed and represent the characteristics of the new cultivar. The new Scirpus pendulus has not been observed under all possible environmental conditions. These attributes in combination distinguish ‘Stars and Stripes’ from all other selections of Scirpus pendulus known to the Inventor. The new Scirpus pendulus plant named ‘Stars and Stripes’ has shown the variegated foliage giving the plant a showier foliar display to be unique and stable.

Plants of the new Scirpus pendulus can be compared to plants of Scirpus pendulus the species, not patented. The new Scirpus pendulus has variegated foliage compared to the species which has all green foliage. More specifically the leaves of the new Scirpus pendulus plant named ‘Stars and Stripes’ have yellow centers and green edges to the foliage.

For the sake of comparison to other related known Scirpus pendulus varieties, there are none that the breeder knows of.
