Verbena plant named ‘Lan Reda07’

Abstract

A verbena cultivar particularly distinguished by its red-colored flowers with vigorous and free-branching multiple secondary lateral branches, low and outwardly spreading growth habit, and tolerance to powdery mildew is disclosed.

Description

Genus and species: Verbena hybrida.

Variety denomination: ‘Lan Reda07’.

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 Reda07’. The new cultivar originated in 2004 in Gilroy, Calif. from an hybridization of female parent ‘Lan Redtwo’ (U.S. Plant Pat. No. 17,842), with red flowers, and male proprietary line ‘1579-2’ (unpatented), having a purple flower color with an eye.

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.

Plant 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 horizontal practices in Gilroy, Calif. and Andijk, The Netherlands.

• • 1. Red flower color;
  • 2. Low and outwardly spreading growth habit;
  • 3. Vigorous and free branching with multiple secondary lateral branches; and
  • 4. Tolerance to powdery mildew.

DESCRIPTION OF PHOTOGRAPHS

This new verbena plant is illustrated by the accompanying photographs which show overall plant habit, including blooms, buds and foliage of 18 to 22 week-old plants. The plants were grown in a greenhouse before being moved outside in Andijk, The Netherlands during the summer months. The photographs were taken in August 2005. 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 Reda07’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken from plants approximately 20-24 weeks old, grown in 6-inch pots, in Gilroy, Calif. in the summer season. The plants had one plant growth regulator treatment and one terminal pinch after cuttings were transplanted to 4-inch pots and then to 6-inch pots. Color readings were taken in a LEXAN-covered greenhouse in summer under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (RHS) (2001 edition). Texture description details were observed with a dissecting microscope.

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Lan Reda07’ differs from the female parent ‘Lan Redtwo’ (U.S. Plant Pat. No. 17,842) in that ‘Lan Reda07’ is more compact, has less pinnatisect foliage and slightly larger foliage that ‘Lan Redtwo’.

‘Lan Reda07’ differs from the male parent, proprietary line ‘1579-2’ (unpatented) in that ‘Lan Reda07’ is more compact, has red-colored flowers and is more floriferous, while ‘1579-2’ has a purple flower color.

‘Lan Reda07’ differs from the commercial variety ‘Lan Chered’ (U.S. Plant Pat. No. 15,602) in that ‘Lan Reda07’ has longer stems and internodes, less branching and lighter green, smaller leaves that ‘Lan Chered’. Additionally, ‘Lan Reda07’ also has a velvety red flower color, while ‘Lan Chered’ has a more cherry-red flower color.
