Lantana plant named ‘2003.219’

Abstract

A new and distinct cultivar of Lantana plant named 2003.219, characterized by its relatively large, 2″ umbels, flower color which is salmon/orange at opening, maturing to a yellow/orange and then to a lavender purple, and by its moderate vigor with an upright habit and excellent branching.

Description

The present invention relates to a new and distinct cultivar of Lantana plant, botanically known as Lantana camara, and referred to by the varietal denomination ‘2003.219’.

The new cultivar is the product of a planned breeding program carried out by the inventor in Bozen, Italy. The female or seed parent was the proprietary cultivar Lantana camara ‘Viola’ (not patented), and the male or pollen parent was the proprietary cultivar Lantana camara ‘Mini red’ (not patented). The objective of the breeding program was to create Lantana cultivars having new colors, large flowers, and a compact growth habit.

The new cultivar was selected by the inventor from the progeny of the stated cross in a cultivated area in Bozen, Italy. The first act of asexual reproduction of the new cultivar was accomplished when vegetative cuttings were from the selection on May 3, 2003 in a controlled environment in Bozen, Italy, by or under the supervision of the inventor. Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics of the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Loudon, N.H. and Bonsall, Calif. under normal commercial growing conditions.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and have been determined to be basic characteristics of the new cultivar, which in combination distinguish the new cultivar as being new and distinct:

• • 1. The umbels of the new cultivar are very large, being 2 inches in diameter.
  • 2. As the flower buds expand, the opening color is salmon-orange. When the flowers are fully open, the color is a bright yellow to yellow orange, and as the flowers age, the flower color changes first to salmon orange and then to lavender purple. Under brighter light and cooler temperatures, the flower color tends to intensify.
  • 3. The new cultivar has moderate vigor, with an upright habit and excellent branching. Internode length ranges between 2″ and 3″.
  • 4. The leaves are ovate in shape, and when fully expanded are 4-5″ in length and 2-3″ in width at the widest point.

The new cultivar differs from its male parent primarily by its upright growth habit, larger leaf size, and the lavender purple color of its fully mature and aging flowers. The new cultivar differs from its female parent primarily by its upright habit and its large flower size.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new cultivar is the cultivar ‘Anne Marie’, disclosed in U.S. Plant Pat. No. 11,310. In comparisons made in Loudon, N.H., plants of the new cultivar were significantly more vigorous than plants of ‘Anne Marie’. In addition, when the flowers of the new cultivar are expanding to a fully open condition, the yellow to yellow-orange flower color is distinctly different than the orange-red flower color of ‘Anne Marie’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph at the bottom of the single sheet comprises a front perspective view of a typical flowering plant of the new cultivar. The photograph at the top shows a series of fully open flowers of the new cultivar. The photographs show the colors of the new cultivar as true as is reasonably possible with colored reproductions of this type. If any differences exist between the photographic color and the color values described below, the values in the detailed description are accurate.
