Scaevola plant named ‘Scablhatis’

Abstract

A new and distinct Scaevola plant named ‘Scablhatis’, characterized by its spreading and cascading growth habit and blue flowers that have a big light yellow eye.

Description

Latin name of the genus and species of the plant claimed: Scaevola aemula.

Varietal denomination: ‘Scablhatis’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Scaevola plant, botanically known as Scaevola aemula, synonym Scaevola saligna and hereinafter referred to by the cultivar name ‘Scablhatis.’

The new cultivar originated from a cross made in 1999 of two selections of Scaevola aemula: ‘SC100’ as female parent and an open pollinated unidentified variety as pollen male parent. Both of these selections are not commercially available and not known by any synonyms.

The new Scaevola plant was selected as a flowering plant within the progeny of this cross in a controlled environment in Enkhuizen, The Netherlands. Plants of the new Scaevola have blue flowers whereas plants of the unidentified selections have purple/blue flowers which is typical for the species Scaevola aemula.

The new Scaevola plant has been asexually reproduced by cuttings in Enkhuizen, The Netherlands and Sarrians, France over a two year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed.

SUMMARY OF THE INVENTION

The new cultivar has not been observed under all possible environment conditions. The phenotype may vary somewhat with variations in environmental such as temperature, day length and light intensity, without, however, any variance in genotype. This description is made under the following greenhouse conditions: day length: from 13 to 15 hours per day, temperature: day 22 degrees Celsius, night 16 degrees Celsius.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Scablhatis,’ which distinguish ‘Scablhatis’ as a new and distinct cultivar.

• • 1) Low-growing, spreading and cascading growth habit.
  • 2) Medium internodes, dense and bushy plant form and freely branching plant habit.
  • 3) Very freely flowering, more than 600 flowers and flower buds per plant.
  • 4) Unique very large blue fan-shaped flowers with light green-yellow eye.

DESCRIPTION OF THE DRAWING

This new Scaevola plant is illustrated by the accompanying photographic drawing which shows 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 characteristics of this new Scaevola plant. The data that define these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 16 week old plants, blossomed under natural light in a greenhouse and grown in a 13 cm container. Colour readings were taken in the greenhouse under ambient light. Colour references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
