Abstract

A new Verbena plant particularly distinguished by its large scarlet flower, early flowering, and a semi-erect habit that becomes spreading as plant develops.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Verbena, botanically known as Verbena×hybrida. The new cultivar is propagated from cuttings resulting from the cross of ‘X813’ and ‘V480’. ‘X813’ is a scarlet flowering Verbena having a spreading habit. ‘X813’ is not commercially available and is not known by any synonyms. ‘V480’ is a scarlet flowering Verbena having an erect habit. ‘V480’ is not commercially available and is not known by any synonyms. Neither ‘X813’ or ‘V480’ has been patented. As a result of this cross the present cultivar was created in 1994 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed. This new Verbena plant is an annual in most climatical zones in the US, except in zones 8, 9 and 10, where it is a perennial plant.

DESCRIPTION OF THE DRAWING

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

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive charactertistics of this new Verbena. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 14 weeks old plants, blossomed under natural light in a greenhouse. Color readings were taken in the greenhouse under ambient light. Color references are primarily to The R.H.S. Color Chart of The Royal Horticultural Society of London.

Reproductive Organs

One pistil and 4 stamens in pairs; color for both is yellow green 150B. The pistil size is 15-17 mm in length. Pollen is not present. The filaments and anthers are fused to the corolla. The anthers are enclosed and not a prominent feature of the flower. ‘Scarlena’ does not freely set seed.

Claims

What is claimed is:

1. A new and distinct variety of Verbena plant, substantially as herein illustrated and described, characterized particularly as to novelty by larger scarlet flowers than other Verbena plants, which appear earlier on the plant, and a growing habit that is first semi-erect, but later spreading and hanging.
