Genus and species: Lantana camara.
Variety denomination: ‘SAILAN002’.
BACKGROUND
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 ‘SAILAN002’.
The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during June 2017. The objective of the breeding program was the development of Lantana cultivars with a semi-mounded growth habit, white flower color and excellent heat tolerance.
The new Lantana cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Lantana camara breeding selection coded ‘3566-B-2’, not patented, characterized by its light orange colored inflorescences, medium green colored foliage, and vigorous, semi-upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Lantana camara breeding selection coded ‘18265’, not patented, characterized by its medium pink colored inflorescences, medium green colored foliage, and moderately vigorous, compact growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated cross-pollination during May 2018 in a controlled environment in Guadalupe, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since May 2018 in Guadalupe, Calif. and Arroyo Grande, Calif. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.
SUMMARY
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘SAILAN002’ as a new and distinct cultivar of Lantana plant:
- 1. Semi-mounding growth habit;
- 2. White flower color with yellow near the throat that fades away with age; and
- 3. Excellent heat tolerance.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs, taken on Sep. 16, 2020 in Salinas, Calif. which show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘SAILAN002’.

DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.
The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used.
The following descriptions and measurements were collected in September of 2020 and obtained from plants grown 4.25 months from transplant into 6-inch pots from rooted cuttings in Salinas, Calif., under greenhouse conditions.

The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N Grow (1 solution:9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24C.
