Lantana plant named ‘LANZ0012’

Latin name of the genus and species of the plant claimed: Lantana camara.

Varietal denomination: ‘LANZ0012’.

The present invention comprises a new Lantana , botanically known as Lantana camara , and hereinafter referred to by the variety name ‘LANZ0012’.

‘LANZ0012’ is a product of a planned breeding program. The new cultivar has uniform golden yellow flowers, large inflorescences, green foliage, and vigorous trailing but tight branching plant habit.

‘LANZ0012’ originated from an X-ray mutagen treatment from ‘Bant Tragol’ (U.S. Plant Pat. No. 20,557). The treatment was made in Jan. 10, 2010 in a lab in Andijk, The Netherlands. The mutated young plants were grown in greenhouse in Apr. 15, 2011 in Gilroy, Calif. The ‘Bant Tragol’ plant has slightly lighter flower color, looser trailing plant habit, and slightly smaller flower size than ‘LANZ0012’.

The ‘LANZ0012’ was grown again in Apr. 10, 2012 in greenhouse in Gilroy, Calif. In the same year, it was also trialed in summer fields in Gilroy, Calif., Grand Rapids, Mich., and Enkhuizen, The Netherlands. The product advancement decision was made in Sep. 25, 2012 after above field trials were completed.

The first act of asexual reproduction of ‘LANZ0012’ was accomplished when vegetative cuttings were propagated from the initial selection in a greenhouse in Gilroy, Calif., in Apr. 15, 2011.

Horticultural examination of plants grown from cuttings of the plant initiated on Apr. 15, 2011 in Gilroy, Calif., and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘LANZ0012’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘LANZ0012’ 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.

A Plant Breeder's Right for this cultivar was not yet applied for. ‘LANZ0012’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Lantana as a new and distinct variety.

The accompanying photographic drawings show typical flower and foliage characteristics of ‘LANZ0012’ with colors being as true as possible with an illustration of this type.

FIG. 1 shows a close-up of an inflorescence and FIG. 2 shows a flowering potted plant of the new variety.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.

The plant descriptions and measurements were taken in Gilroy, Calif. in October 2015. The plants were approximately 28 weeks old and were growing in a 14 inch pot outdoors.
