plant named ‘Red October’

Abstract

A new, distinct Andropogon gerardii plant as shown and described, characterized by a more upright plant with a height of 130-150 cm, dark green colored foliage with red tips most of the growing season, and burgundy red fall color that turns scarlet.

Description

Latin name: Andropogon gerardii.

Cultivar name: ‘Red October’.

BACKGROUND OF THE INVENTION

The present invention relates to a new form of Andropogon gerardii plant named ‘Red October’. ‘Red October’ is a seedling of Andropogon gerardii ‘Indian Warrior’, United States plant patent applied for, characterized by a more upright plant with a height of 130-150 cm, dark green colored foliage with red tips most of the growing season, and burgundy red fall color that turns scarlet, compared to green to red foliage and the taller habit of 150-180 cm of the parent plant. The new plant was sown as an open pollinated seed from Andropogon gerardii ‘Indian Warrior’, U.S. Plant Pat. No. 24,999, by the inventor at a wholesale perennial nursery in Hebron, Ill. in 2009. The seedling was grow was grown at a nursery in Hebron, Ill. The selection of this plant was due to its more upright growth, shorter habit, dark green foliage with red tips and burgundy red fall color that turns scarlet. Asexual, vegetative division propagation has been the only means of reproduction. Propagation has taken place at Hebron, Ill. since 2010. In 2011 we planted 100 plants in 3 gallon pots, to date these plants have remained uniform in height, and foliage color. The new plant Andropogon gerardii ‘Red October’ has shown to be stable and identical in reproduction to the parent after making over 1200 vegetative divisions from 2010 to 2013.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (copyright 2001). The new Andropogon gerardii plant named ‘Red October’ has shown the characteristics of a more upright plant with a height of 130-150 cm, dark green colored foliage with red tips most of the growing season, and burgundy red fall color that turns scarlet to be unique and stable. For purpose of the comparison the new plant will be referred to as ‘Red October’.

Plants of ‘Red October’ can be compared to plants of Andropogon gerardii ‘Indian Warrior’, U.S. Plant Pat. No. 24,999. 1. ‘Red October’ has more upright growth and a height in the range of 130-150 cm compared to the height of Andropogon gerardii ‘Indian Warrior’ which has an average height of 150-180 cm. 2. ‘Red October’ has a foliage color of RHS 147A coloring to N 92 A and eventually close to 187 C compared to Andropogon gerardii ‘Indian Warrior’ which has foliage color of 137 A coloring to N 77 A.

Plants of ‘Red October’ can be also be compared to plants of Andropogon gerardii ‘Red Bull’ not patented. 1. The ‘Red October’ has a height in the range of 130-150 cm compared to the height of Andropogon gerardii ‘Red Bull which has an average height of 180-210 cm. 2. The new Andropogon has a foliage color of RHS 147A coloring to N 92 A and eventually close 187 C compared to Andropogon gerardii ‘Red Bull’ which has foliage color that is lighter green close to RHS 136C. 3. ‘Red October’ has a uniform red fall color N 92 A and is propagated by division while the Andropogon gerardii ‘Red Bull’ has a variable orange red fall color and is propagated by seed.
