Abstract

A new, distinct Pennisetum alopecuroides plant as shown and described, characterized by thick greyed-purple inflorescences on 74 cm stems that start in late August in northern Illinois.

Description

Latin name: Pennisetum alopecuroides.

Cultivar name: ‘Love and Rockets’.

BACKGROUND OF THE INVENTION

The present invention relates to a new form of Pennisetum alopecuroides plant named ‘Love and Rockets’. ‘Love and Rockets’ is a seedling of an unnamed Pennisetum alopecuroides, not patented, characterized by thick greyed-purple inflorescences on 74 cm stems that start in late 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 thick greyed-purple inflorescences on 74 cm stems that start in late 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 ‘Love and Rockets’ has shown the characteristic of thick greyed-purple inflorescences on 74 cm stems that start in early September 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 74 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 15 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 74 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 15 cm compared to Pennisetum alopecuroides ‘Hameln’ which has an inflorescence length of 10 cm. 3. The new Pennisetum has a greyed-purple 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 ‘Moudry’, not patented. 1. The new Pennisetum has a height of 74 cm compared to the height of Pennisetum alopecuroides ‘Moudry’ which has a height closer to 60 cm. 2. The new Pennisetum has a late August bloom time compared to Pennisetum alopecuroides ‘Moudry’ which typically blooms in October.
