Description

Genus and species: Lachenalia Jacq. f. ex Murray.

Variety denomination: ‘Rainbow Bells’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lachenalia, botanically known as Lachenalia Jacq. f. ex Murray having the common name of Viooltjies/Cape cowslip and hereinafter referred to by its variety denomination ‘Rainbow Bells’.

The variety was first cultivated in 2008 and originated by means of conventional breeding by the inventor during 2009 to 2010 at the premises of Agricultural Research Council Vegetable and Ornamental Plant Institute, Roodeplaat, Pretoria, Republic of South Africa.

Asexual reproduction of the ‘Rainbow Bells’ plant at the same location has shown that the unique features thereof are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of Lachenalia which originated from an inter-species cross between two different accessions of Lachenalia flava as detailed herein below.

The following traits have been repeatedly observed and are determined to be the unique characteristics, under the local evaluation conditions, of the ‘Rainbow Bells’ plant. These characteristics in combination distinguish ‘Rainbow Bells’ as a new and distinct Lachenalia cultivar:

    • 1. Bulb plant type having a spreading growth habit of a height of 15-30 centimeters (cm) and width of 10-15 cm.
    • 2. Flower color: red (RHS #53A) when opening, yellow (RHS #9A) when open; multicolored yellow (RHS #9A), orange (RHS #32A) and red/maroon (RHS #45A) tip.
    • 3. Flower form: Bell shaped.

Color references are made to The R.H.S. Color Chart, 1st edition, 1966, except where general color terms of ordinary significance are used or indicated otherwise.

Plants of the new Lachenalia variety ‘Rainbow Bells’ can be compared to similar denominations such as ‘Romelia’ and ‘Namakwa’. ‘Romelia’ has plain yellow bell-shaped flowers whereas ‘Rainbow Bells’ has multicolored bell-shaped flowers having an orange (RHS #32A) base, turning yellow (RHS #9A) ending in a red/maroon (RHS #45A) tip. ‘Romelia’ does not have widely recurving tips like ‘Rainbow Bells’, but the stamens are included as opposed to the exerted stamens of ‘Rainbow Bells’. The inflorescence is not as dense as that of ‘Rainbow Bells’. The flowers of ‘Rainbow Bells’ are furthermore shorter than those of ‘Romelia’. ‘Namakwa’ has plain yellow flowers with reddish tips and are of tubular shape. The flower orientation of ‘Namakwa’ is horizontal whilst the orientation of ‘Rainbow Bells’ is hanging.

BRIEF DESCRIPTION OF THE DRAWINGS

The first drawing illustrates the overall appearance of the ‘Rainbow Bells’, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The first drawing comprises a front perspective view of a typical ‘Rainbow Bells’ grown in an indoor nursery.

 DETAILED DESCRIPTION

The aforementioned drawings, following observations and measurements describe ‘Rainbow Bells’ grown by the inventor on behalf of Agricultural Research Council Vegetable and Ornamental Plant Institute, Roodeplaat, Pretoria, Republic of South Africa. Thereafter ‘Rainbow Bells’ was made subject of a South African Plant Breeders' Right application in March 2009. This application was granted in 2010 under number ZA20104396.

The plant may be used for landscaping and should be planted during the month of March; indoors and in pots only. The plant should be kept at temperatures of 20-25 degrees Celsius during the day and 10-15 degrees Celsius at night. Plenty of light should be provided.

‘Rainbow Bells’ is an early flowering cultivar with an exceptional keeping quality.

‘Rainbow Bells’ originated from an inter-species cross between Lachenalia flava accession number L102 (female parent) and Lachenalia flava accession number L144 (male parent).

The female parent has pure yellow flowers with spots on the leaves, whereas the male parent has plain yellow flowers with widely recurving tips and spots on the leaves.

A specific seedling with number 1996/32/21 was selected from the parental cross described above and thereafter asexually propagated. The asexual progeny of this seedling is the cultivar ‘Rainbow Bells’ and was multiplied via tissue culture at the premises of Agricultural Research Council Vegetable and Ornamental Plant Institute, Roodeplaat, Pretoria, Republic of South Africa.
