plant named ‘Pure Energy’

Abstract

A new, distinct Pennisetum alopecuroides plant as shown and described, characterized by yellow-green foliage RHS color 153 A-D inflorescences on 70 cm stems that start in mid-August in northern Illinois.

Description

Latin name: Pennisetum alopecuroides.

Cultivar name: ‘Pure Energy’.

BACKGROUND OF THE INVENTION

The present invention relates to a new form of Pennisetum alopecuroides plant named ‘Pure Energy’. ‘Pure Energy’ is a seedling of an unnamed Pennisetum alopecuroides, not patented., characterized by yellow-green foliage RHS color 153 A-D, inflorescence RHS color 145 B, on 70 cm stems that start in mid-August in northern Illinois. The new plant is the result of a breeding program taking place at a wholesale perennial nursery since 2001. The seedling was grown by the inventor at a wholesale perennial nursery in Hebron, Ill. in 2018. The selection of the new plant was due to its yellow-green colored foliage, RHS 153 A-D, inflorescence RHS color 145 B on 70 cm stems that start in mid-August in northern Illinois. Asexual, vegetative division propagation has been the only means of reproduction. Propagation has taken place at a wholesale perennial nursery Hebron, Ill. in 2011. To date these plants have remained uniform in height. The new Pennisetum has shown to be stable and identical in reproduction to the parent after making over 500 vegetative divisions from 2018 to 2019. No plants of the new Pennisetum alopecuroides 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.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart. The new Pennisetum alopecuroides plant named ‘Pure Energy’ has shown the characteristic of yellow-green foliage RHS color 153 A-D, inflorescence RHS color 145 B, on 70 cm stems that start in mid-August in northern Illinois.

The parent plants were not available for comparison. Plants of the new Pennisetum can be compared to plants of Pennisetum alopecuroides ‘Red Head’, not patented. 1. The new Pennisetum has a height of 70 cm compared to the height of Pennisetum alopecuroides ‘Red Head’ which has a height of 120 cm. 2. The new Pennisetum has an inflorescence length of 13 cm compared to Pennisetum alopecuroides ‘Red Head’ which has an inflorescence length of 20 cm.

Plants of the new Pennisetum can be compared to plants of Pennisetum alopecuroides ‘Hameln’ not patented. 1. The new Pennisetum has a height of 70 cm compared to the height of Pennisetum alopecuroides ‘Hameln’ which has a height of 90 cm. 2. The new Pennisetum has an inflorescence length of 13 cm compared to Pennisetum alopecuroides ‘Hameln’ which has an inflorescence length of 10 cm. 3. The new Pennisetum has a yellow-green inflorescence color compared to Pennisetum alopecuroides ‘Hameln’ which has a tan inflorescence color.

Plants of the new Pennisetum can be compared to plants of Pennisetum alopecuroides ‘Mondry’, not patented. 1. The new Pennisetum has a height of 70 cm compared to the height of Pennisetum alopecuroides ‘Mondry’ which has a height closer to 60 cm. 2. The new Pennisetum has a mid-August bloom time compared to Pennisetum alopecuroides ‘Moudry’ which typically blooms in October.
