Lantana plant named ‘Samson’

Abstract

A distinct cultivar of Lantana plant named ‘Samson’, characterized by its upright, mounded and outwardly spreading plant habit; freely branching habit; freely and consistent flowering habit; golden yellow and orange-colored flowers; and excellent garden performance.

Description

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 ‘Samson’.

The new Lantana was discovered by the Inventor in Clinton, Miss., as a naturally-occurring branch mutation of an unidentified selection of Lantana camara.

Asexual reproduction of the new cultivar by terminal cuttings taken in Clinton, Miss., since the summer of 1999, has shown that the unique features of this new Lantana are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘Samson’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature, light intensity, daylength, water status, and/or fertilizer rate or type without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Samson’. These characteristics in combination distinguish ‘Samson’ as a new and distinct cultivar:

1. Upright, mounded and outwardly spreading plant habit.

2. Freely branching.

3. Freely and consistently flowering.

4. Golden yellow and orange-colored flowers.

5. Excellent garden performance.

Plants of the new Lantana differ from plants of the parent selection primarily in flower color as plants of the parent selection have yellow and red colored inflorescences.

Plants of the new Lantana can be compared to plants of the cultivar ‘Sonrise’, disclosed in U.S. Plant Pat. No. 10,856. However, in side-by-side comparisons conducted by the Inventor in Clinton, Miss., plants of the new Lantana differ from plants of the cultivar ‘Sonrise’ in the following characteristics:

1. Plants of the new Lantana are more freely and more consistently flowering than plants of the cultivar ‘Sonrise’.

2. Plants of the new Lantana and the cultivar ‘Sonrise’ differ in flower coloration.

Plants of the new Lantana can also be compared to plants of the cultivar ‘Radiation’, not patented, which is similar in flower color to plants of the new Lantana. However, in side-by-side comparisons conducted by the Inventor in Clinton, Miss., plants of the new Lantana differ from plants of the cultivar ‘Radiation’ in the following characteristics:

1. Plants of the new Lantana are more upright, uniform, mounded and vigorous than plants of the cultivar ‘Radiation’.

2. Plants of the new Lantana are more freely and more consistently flowering than plants of the cultivar ‘Radiation’.

3. Plants of the new Lantana are more hardy than plants of the cultivar ‘Radiation’.
