USPP24120P3 - Lantana plant named ‘Sunset Orange’ - Google Patents

Abstract

A new and distinct cultivar of Lantana plant named ‘Sunset Orange’, characterized by its low growing, mounding to spreading growth habit; leathery, scabrous dark green foliage; continuous flowering; and light orange flower buds that open to light orange and age to dark orange.

Description

Genus and species of plant claimed: Lantana sp.

Variety denomination: ‘Sunset Orange’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana sp., and hereinafter referred to by the cultivar name ‘Sunset Orange’.

The new Lantana plant originated from a controlled cross between Lantana sp. ‘Chapel Hill Gold’ (U.S. Plant Pat. No. 21,539) and an unnamed seedling of Lantana camara known to the inventor as Lantana camara DIO (not patented) as part of a planned breeding program to develop low growing, continuously flowering lantanas with dark green foliage. The cultivar ‘Sunset Orange’ originated and was discovered in a cultivated environment in a greenhouse 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 ‘Sunset Orange’ 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 ‘Sunset Orange’. These characteristics in combination distinguish ‘Sunset Orange’ as a new and distinct cultivar: 1. Low growing, mounding to spreading growth habit; 2. Leathery, scabrous dark green foliage; 3. Continuous flowering; and 4. Light orange flower buds that open to light orange and age to dark orange. There are no other cultivars of Lantana with this combination of characteristics known to the inventor.

Plants of the new Lantana ‘Sunset Orange’ differ from plants of the female parent, ‘Chapel Hill Gold’, primarily in flower color and growth habit as plants of ‘Chapel Hill Gold’ have bright golden yellow flower buds and flowers and a spreading growth habit, whereas plants of ‘Sunset Orange’ have light orange flower buds that open to light orange and age to dark orange, and a mounding to spreading growth habit. Plants of the new Lantana ‘Sunset Orange’ differ from plants of the male parent, an unnamed seedling known to the inventor as Lantana DIO, primarily in flower color and growth habit, as plants of the male parent have flowers that remain light orange and a loose, rounded growth habit, whereas plants of ‘Sunset Orange’ have flowers that open light orange and age to dark orange, and an overall more compact, mounding to spreading growth habit.

‘Sunset Orange’ can be compared to the cultivar ‘Bani Redda’ (U.S. Plant Pat. No. 21,452), but differs in the growth habit, foliage, and floral characteristics. ‘Sunset Orange’ has a low growing, mounding to spreading and overall larger growth habit, whereas ‘Bani Redda’ has a compact and dense mounding and overall smaller growth habit. ‘Sunset Orange’ has overall smaller foliage than ‘Bani Redda’. ‘Sunset Orange’ averages 23 flowers per inflorescence, whereas ‘Bani Redda’ averages 33 flowers per inflorescence. ‘Sunset Orange’ has light orange flowers that mature to dark orange, whereas ‘Bani Redda’ has yellow flowers that mature to orange-red.
