Lantana plant named ‘LAX 600’

Abstract

A new and distinct cultivar of Lantana plant named ‘LAX 600’, characterized by its compact, upright and somewhat outwardly spreading plant habit; short internodes; relatively small leaves; early, freely and continuous flowering habit; inflorescences with initially golden yellow-colored flowers that become orange and eventually light red with development; and low seed set.

Description

Botanical designation: Lantana camara.

Cultivar denomination: ‘LAX 600’.

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 LAX 600.

The new Lantana is a product of a planned breeding program conducted by the Inventor in Hawthorne, Fla. The objective of the breeding program is to create compact Lantanas with little to no seed set.

The new Lantana originated from an open pollination in September, 1999 of the Lantana cultivar Tangerine, not patented, as the female, or seed parent, with an unidentified Lantana selection as the male, or pollen parent. The new Lantana was selected as a single flowering plant from the resulting progeny of the open pollination by the Inventor in a controlled environment in Hawthorne, Fla. in June, 2000, on the basis of its growth habit and attractive flower coloration.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Hawthorne, Fla., since July, 2000, 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 LAX 600 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture 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 ‘LAX 600’. These characteristics in combination distinguish ‘LAX 600’ as a new and distinct Lantana cultivar:

• • 1. Compact, upright and somewhat outwardly spreading plant habit.
  • 2. Short internodes.
  • 3. Relatively small leaves.
  • 4. Early, freely and continuous flowering habit.
  • 5. Inflorescences with initially golden yellow-colored flowers that become orange and eventually light red with development.
  • 6. Low seed set.

Plants of the new Lantana can be compared to plants of the female parent, the cultivar Tangerine. In side-by-side comparisons conducted in Hawthorne, Fla., plants of the new Lantana differed from plants of the cultivar Tangerine in the following characteristics:

• • 1. Plants of the new Lantana were more compact than plants of the cultivar Tangerine.
  • 2. Plants of the new Lantana had shorter internodes than plants of the cultivar Tangerine.
  • 3. Plants of the new Lantana were more freely flowering than plants of the cultivar Tangerine.
  • 4. Plants of the new Lantana had golden yellow, orange and light red-colored flowers whereas plants of the cultivar Tangerine had orange-colored flowers.
  • 5. Plants of the new Lantana produced fewer seeds than plants of the cultivar Tangerine.

Plants of the new Lantana can be compared to plants of the cultivar Robpatcow, disclosed in U.S. Plant Pat. No. 12,450. In side-by-side comparisons conducted in Hawthorne, Fla., plants of the new Lantana differed from plants of the cultivar Robpatcow in the following characteristics:

• • 1. Plants of the new Lantana were taller than plants of the cultivar Robpatcow.
  • 2. Plants of the new Lantana flowered earlier than plants of the cultivar Robpatcow.
  • 3. Plants of the new Lantana were more freely flowering than plants of the cultivar Robpatcow.
  • 4. Plants of the new Lantana had golden yellow, orange and light red-colored flowers whereas plants of the cultivar Robpatcow had yellow orange and orange-colored flowers.
  • 5. Plants of the new Lantana were more resistant to Botrytis than plants of the cultivar Robpatcow.

Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Lantana. The photograph comprises a side perspective view of a typical flowering plant of ‘LAX 600’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
