USPP27252P3 - Lantana plant named ‘PIIL-I’ - Google Patents

Abstract

A new and distinct cultivar of Lantana plant named ‘PIIL-I’, characterized by its low growing, layered and spreading growth habit; leathery, scabrous, lustrous dark green foliage; continuous flowering; and dark yellow flower buds that open to dark yellow and age to orange and eventually to orange-red. There are no other cultivars of Lantana with this combination of characteristics known to the inventor.

Description

Genus and species of plant claimed: Lantana camara L.

Variety denomination: ‘PIIL-I’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and hereinafter referred to by the cultivar name ‘PIIL-I’.

The new Lantana plant originated from a controlled cross between Lantana camara ‘Dallas Red’ (not patented), female parent, and Lantana camara ‘Sunset Orange’ (U.S. Plant Pat. No. 24,120), male parent, as part of a planned breeding program to develop low growing, continuously flowering lantanas with dark green foliage. The cultivar ‘PIIL-I’ originated and was discovered in a cultivated environment in Watkinsville, Ga.

Asexual reproduction of the new cultivar by stem cuttings in Watkinsville, Ga. has shown that all the unique features of this new Lantana, as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘PIIL-I’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIIL-I’. These characteristics in combination distinguish ‘PIIL-I’ as a new and distinct cultivar: 1. Low growing, layered and spreading growth habit; 2. Leathery, scabrous, lustrous dark green, fragrant foliage; 3. Continuous flowering; and 4. Dark yellow flower buds that open to dark yellow, age to orange and then eventually to orange-red. There are no other cultivars of Lantana with this combination of characteristics known to the inventor.

Plants of the new Lantana camara ‘PIIL-I’ differ from plants of the male parent, ‘Sunset Orange’, (U.S. Plant Pat. No. 24,120) primarily in flower color, as plants of ‘Sunset Orange’, (U.S. Plant Pat. No. 24,120) have light orange flower buds that open to light orange and age to dark orange, whereas plants of ‘PIIL-I’ have buds that open to dark yellow and age to orange eventually to orange-red. Plants of the new Lantana camara ‘PIIL-I’ are more spreading in habit compared to the stiff, bushy, habit of Lantana camara ‘Sunset Orange’.

Plants of the new Lantana can be compared to plants of Lantana camara ‘Dallas Red’ (unpatented), the female parent, mainly in flower color. ‘PIIL-I’ starts off as dark yellow turns to orange and ages to orange-red, whereas plants of Lantana camara ‘Dallas Red’ (unpatented) start off red turn to orange and yellow with aging.

Plants of the new Lantana ‘PIIL-I’ can be compared to plants of Lantana sp. ‘Chapel Hill Gold’ (U.S. Plant Pat. No. 21,539) primarily in flower color and cold hardiness. Plants of ‘PIIL-I’ flowers start off dark yellow and turn to orange and then age to orange-red, whereas plants of Lantana ‘Chapel Hill Gold’ start off bright yellow gold and remain that color. Plants of ‘Chapel Hill Gold’ are cold hardy in USDA zone 7. Plants of ‘PIIL-I’ are not cold hardy. In zone 7 they are annuals.
