Heliotropium plant named ‘KLEHA07520’

Abstract

A new cultivar of Heliotropium particularly characterized by purple-blue flowers, a medium/compact growth habit and flowers with a vanilla-hyacinth-like fragrance, is disclosed.

Description

Genus and species: Heliotropium arborescens.

Variety denomination: ‘KLEHA07520’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Heliotropium, botanically known as Heliotropium arborescens, and hereinafter referred to by the cultivar name ‘KLEHA07520’. ‘KLEHA07520’ was discovered as a seedling resulting from a cross in summer 2003 in Stuttgart, Germany between the proprietary female Heliotropium parent, ‘V 018’ (unpatented) and the male parent, an unnamed typical individual plant of Heliotropium (unpatented). A single plant selection was subsequently chosen for further evaluation and for asexual propagation.

The new cultivar was created in 2003 in Stuttgart, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Stuttgart, Germany over a three and one-half-year period. ‘KLEHA07520’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Canada on Apr. 11, 2007. ‘KLEHA07520’ has not been made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal commercial practices in a greenhouse in Stuttgart, Germany.

• • 1. Purple-blue flowers;
  • 2. A medium/compact growth habit; and
  • 3. Flowers with a vanilla-hyacinth-like fragrance.

DESCRIPTION OF THE PHOTOGRAPHS

This new Heliotropium plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants about 4-months old and grown from rooted cuttings in a 12-cm pot under greenhouse (glasshouse) in Stuttgart, Germany under conditions which approximate those generally used in commercial practice.

FIG. 1 shows the whole plant habit, including blooms, buds and foliage.

FIG. 2 shows a close-up of the mature flowers.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘KLEHA07520’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on 3-month old plants in 12-cm pots that were pinched once approximately 6 days after planting and grown in a greenhouse in February through April. The color readings were determined under natural light. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
