Abstract

A new and distinct cultivar of Ligularia plant named ‘Little Rocket’, characterized by its upright, somewhat outwardly spreading and relatively compact plant habit; freely basal branching growth habit; freely flowering habit; and yellow-colored ray and disc florets.

Description

Botanical classification/cultivar designation: Ligularia Hybrida cultivar Little Rocket.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Ligularia plant, botanically known as Ligularia Hybrida, and hereinafter referred to by the name ‘Little Rocket’.
The new Ligularia is a product of a planned breeding program conducted by the Inventor in Ter Aar, The Netherlands. The objective of the breeding program is to create new Ligularia cultivars that are more compact.
The new Ligularia originated from a cross-pollination made by the Inventor in Ter Aar, The Netherlands of a proprietary seedling selection originating from a cross-pollination of the Ligularia cultivar Latërnchen and the Ligularia cultivar The Rocket, not patented, as the female, or seed, parent with the Ligularia cultivar The Rocket, not patented, as the male, or pollen, parent. The new Ligularia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Ter Aar, The Netherlands, in 1999.
Asexual reproduction of the new Ligularia by divisions was first conducted in Ter Aar, The Netherlands in 2000. Since then, asexual reproduction by divisions has shown that the unique features of this new Ligularia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Little Rocket has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Little Rocket’. These characteristics in combination distinguish ‘Little Rocket’ as a new and distinct Ligularia:
1. Upright, somewhat outwardly spreading and relatively compact plant habit.
2. Freely basal branching growth habit.
3. Freely flowering habit.
4. Yellow-colored ray and disc florets.
Plants of the new Ligularia differ primarily from plants of the parents in plant height and floriferousness as plants of the parents are not as compact and not as freely flowering as plants of the new Ligularia.
Plants of the new Ligularia can also be compared to plants of the Ligularia cultivar Papillon, not patented. However, plants of the new Ligularia are more compact and have more inflorescences per basal stem than plants of the cultivar Papillon.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Ligularia showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Ligularia.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Little Rocket’ grown in an outdoor nursery.
The photograph at the top of the on the second sheet comprises a close-up view of a typical inflorescence of ‘Little Rocket’.
The photograph at the bottom of the second sheet comprises a close-up view of a typical leaf of ‘Little Rocket’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Lisserbroek, The Netherlands, in an outdoor nursery under full sun conditions. In July, when plants were about two years old, the photographs and the observations and measurements were taken. During this time, day temperatures ranged from 14 to 27° C. and night temperatures ranged from 7 to 14° C. Color references are made to The Royal Horticultural Society Colour Chart, 2001 edition, except where general terms of ordinary dictionary significance are used.
