Abstract

A new and distinct Agapanthus cultivar named ‘Benfran’ is disclosed, characterized by a very short plant form, strong clump formation and an average of at least 5 flowering stems during the flowering season. The new variety is an Agapanthus, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Agapanthus praecox ssp. orientalis.

Variety denomination: ‘Benfran’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a spontaneous, whole plant mutation of the unpatented variety Agapanthus praecox ssp. orientalis ‘Peter Pan’ by the inventor, Frank Benson. The new variety was found in a commercial planting of ‘Peter Pan’ in a nursery in Pallara, Australia. Originally 3 shorter plants were observed in the commercial planting of ‘Peter Pan.’ In 2004 a single plant was selected, which is the new cultivar ‘Benfran.’

Asexual reproduction of the new cultivar ‘Benfran’ by tissue culture was first performed in a commercial laboratory in Dodges Ferry, Tasmania Australia, during 2004, and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Benfran’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Benfran’ These characteristics in combination distinguish ‘Benfran’ as a new and distinct Agapanthus cultivar:

- 1. Distinctive flower light violet to white flower coloration
- 2. Very compact plant size.
- 3. Strong clump formation.
- 4. Production of an average of at least 5 flowering scapes continuously during flowering season.

PARENT COMPARISON

Plants of the new cultivar ‘Benfran’ are similar to plants of the parent variety, Agapanthus praecox ssp. orientalis ‘Peter Pan’ in most horticultural characteristics, however, plants of the new cultivar ‘Benfran’ are shorter and produce more flowering stems than the parent variety.

COMMERCIAL COMPARISON

Plants of the new Agapanthus are best compared to the parent variety, as it is the most similar commercial Agapanthus to ‘Benfran.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘Benfran’ and ‘Peter Pan’ grown outdoors in New South Wales, Australia, during Spring and Summer, in approximately 15 cm nursery pots. Age of the plants photographed are approximately 2 years from a tissue culture planetlet.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Benfran’ plants grown outdoors in New South Wales, Australia The growing temperature ranged from 20° C. to 26° C. during the day and approximately 14° C. to 19° C. at night. The plants were not grown with any kind of shade protection and subject to outdoor, high light conditions. Measurements and numerical values represent averages of typical plant types. No growth retardants were used.
