Verbena plant named ‘Lan Uppurmos’

Abstract

A verbena cultivar particularly distinguished by its violet-purple colored flowers with a white background, vigorous, free-branching with multiple secondary lateral branches, upright growth habit becoming slightly spreading and decumbant, and tolerance to powdery mildew is disclosed.

Description

Genus and species: Verbena hybrida.

Variety denomination: ‘Lan Uppurmos’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of verbena, botanically known as Verbena hybrida, and hereinafter referred to by the cultivar name ‘Lan Uppurmos’. The new cultivar originated in 2003 in Gilroy, Calif. from the sib (two unnamed sister line cross) cross of ‘1773’, an unpatented purple mosaic flowered proprietary verbena.

The seeds produced by the pollination were sown in June 2004. A single plant selection was chosen for further evaluation and for asexual propagation in September 2004.

The new cultivar was created in 2004 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a two-year period. The plant has also been trialed at Gilroy, Calif., Andijk, The Netherlands and Hillscheid, Germany. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plants Breeder's Rights for this cultivar have been applied for in Switzerland on Oct. 30, 2006.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Andikj, The Netherlands.

• • 1. Violet-purple flower color with a white background;
  • 2. Upright plant growth habit becoming slightly spreading and decumbent plant habit;
  • 3. Vigorous and free branching with multiple secondary lateral branches; and
  • 4. Tolerance to powdery mildew.

DESCRIPTION OF PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows overall plant habit, including blooms, buds and foliage of 12 to 14 week old plants. The photographs were taken of plants grown in a greenhouse in Hillscheid, Germany in May 2006. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Lan Uppurmos’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken from plants approximately 12-weeks old, grown in 4-inch pots, in Gilroy, Calif. in the fall and winter seasons. The plants had one plant growth regulator treatment and one terminal pinch at the onset of the trial. Color readings were taken in a LEXAN-covered greenhouse in January under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition). Texture description details were observed with a dissecting microscope.
