Verbena plant named ‘Rap Pur’

Abstract

A verbena cultivar particularly distinguished by purple colored flowers, vigorous growth and low trailing habit.

Description

GENUS AND SPECIES

Verbena hybrida×tenuisecta.

VARIETY DENOMINATION

‘Rap Pur’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of verbena, botanically known as Verbena hybrida×tenuisecta, and hereinafter referred to by the cultivar name ‘Rap Pur’. The new cultivar is asexually reproduced from vegetative cuttings and tissue culture resulting from the cross of the seed/pod parent Temari Purple (PPAF), a purple commercial line×98-66-1, a purple with white eye proprietary line that is unnamed and unpatented.

‘Rap Pur’ is a product of a planned breeding program intended to create new verbena cultivars with purple colored flowers, dark green foliage, vigorous growth and low tailing habit.

The new cultivar was created in 1999 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. over a two year period. The plant has also been trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures.

The drawing shows overall plant habit and the mature inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Rap Pur’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 22 week old plants grown in one gallon pots, in a double poly-greenhouse under natural light and color readings were taken in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.). Texture description details were observed under a dissecting microscope according to The New Royal Horticultural Society Dictionary of Gardening (1992).

COMPARISON WITH PARENTAL CULTIVARS

When the instant plant is compared to male parent 98-663-1 the ‘Rap pur’ plant is purple and no eye as compared to 98-663-1's rose purple with an eye. ‘Rap Pur’ is more mildew tolerant than 98-663-1 and ‘Rap pur’ has slightly broader leaves than 98-663-1.

When ‘Rap pur’ is compared to the female parent ‘Temari purple’ (PPAF) ‘Rap pur’ has smaller flowers and leaves than ‘Temari purple’. ‘Rap pur’ has a more upright basal branching habit than ‘Temari purple’ which has a flat growing and is not very basal branching.
