Description

Latin name: Schizachyrium scoparium.

Cultivar name: ‘Little Red Fox’.

BACKGROUND OF THE INVENTION

The present invention relates to a new form of Schizachyrium scoparium plant named ‘Little Red Fox’. ‘Little Red Fox’ is a seedling selection of Schizachyrium scoparium, characterized by a height of 69 cm, blue-green colored basal foliage with red and purple fall color. The new plant was grown as a seedling of an unnamed selection of Schizachyrium scoparium, by the inventor at a wholesale perennial nursery in Hebron, IL USA in 2019. The selection of this plant was due to its height of 69 cm, and blue-green basal colored foliage with red and purple fall color. Asexual, vegetative division propagation has been the only means of reproduction. Initial vegetative propagation has taken place at Hebron, IL since 2020. In 2022 we planted 500 plants. To date these plants have remained uniform in height, and foliage color. The new Schizachyrium scoparium has shown to be stable and identical in reproduction to the parent after making over 1500 vegetative divisions from 2020 to 2023. No plants of Schizachyrium scoparium plant named ‘Little Red Fox’ 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 nursery in Hebron, IL US and his licensees 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 Apr. 18, 2023.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (copyright 2001). The new Schizachyrium scoparium plant named ‘Little Red Fox’ has shown the characteristics of a height of 69 cm, blue-green colored basal foliage with red and purple fall color to be unique and stable. For purpose of the comparison the new plant will be referred to as ‘Little Red Fox’.

Plants of ‘Little Red Fox’ can be compared to plants of Schizachyrium scoparium ‘Jazz’, not patented. 1. ‘Little Red Fox’ has strong basal blue-green foliage and a height of 69 cm compared to the height of Schizachyrium scoparium ‘Jazz’ which has an average height of 75 cm. 2. ‘Little Red Fox’ has a foliage color of RHS 137 B with 192 D in the stems coloring to 60 A and N186 D compared to Schizachyrium scoparium ‘Jazz’ which has foliage color close to 189 C.

Plants of ‘Little Red Fox’ can also be compared to plants of Schizachyrium scoparium ‘Smoke Signal’, U.S. plant Pat. No. 27,433. 1. The ‘Little Red Fox’ has a height of 69 cm compared to the height of Schizachyrium scoparium ‘Smoke Signal’ which has an average height of 90-120 cm. 2. ‘Little Red Fox’ has a foliage color of RHS 137 B with 192 D in the stems coloring to 60 A and N186 D compared to Schizachyrium scoparium ‘Smoke Signal’ which has foliage color that is, RHS 138 A and RHS 138 B coloring to N187 A and eventually close to 186 B.

Plants of ‘Little Red Fox’ can be also be compared to plants of Schizachyrium scoparium ‘Prairie Blues’, not patented. 1. ‘Little Red Fox’ has a height of 69 cm compared to the height of Schizachyrium scoparium ‘Prairie Blues’ which has an average height of 80-90 cm. 2. ‘Little Red Fox’ has a foliage color of RHS 137 B with 192 D in the stems coloring to 60 A and N186 D compared to Schizachyrium scoparium ‘Prairie Blues’, which has foliage color close to 190 B.
