Abstract
A new and distinct Haworthia plant named ‘LOCK02’, which is characterized by spirally-arranged, light green foliage which is densely covered with prominent linear protuberances presenting as white raised ribs which transversely encircle both the adaxial and abaxial leaf surfaces. The new variety has shown to be uniform and stable in the resulting generations from asexual propagation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Haworthia limifolia.
Variety denomination: The inventive variety of Haworthia hybrid disclosed herein has been given the variety denomination ‘LOCK02’.
This application claims priority to the Community Plant Variety Rights application number 2019/2965, filed Nov. 13, 2019, which is herein incorporated by reference.
Parentage: ‘LOCK02’ is a spontaneous whole-plant mutation of Haworthia limifolia ‘LOCK01’ (Community Plant Variety Rights grant number 28557) which was discovered in the spring of 2010 at a commercial greenhouse in 's-Gravenzande, the Netherlands. The mutation was noted for its light green foliage with prominent white ribs encircling the leaves.
Asexual Reproduction: Asexual reproduction of the new cultivar ‘LOCK02’, by way of meristematic tissue culture, was first initiated in the spring of 2010 at the inventor's commercial greenhouse in 's-Gravenzande, the Netherlands. Through three subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The cultivar ‘LOCK02’ 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 ‘LOCK02’. These characteristics in combination distinguish ‘LOCK02’ as a new and distinct Haworthia cultivar:
-
- 1. ‘LOCK02’ exhibits thick, succulent foliage that is spirally-arranged in a basal rosette; and
- 2. ‘LOCK02’ exhibits long, broad foliage; and
- 3. ‘LOCK02’ exhibits light green foliage which is densely covered with prominent linear protuberances presenting as white raised ribs which transversely encircle both the adaxial and abaxial leaf surfaces.
The following observations and measurements made in October of 2019 describe averages from a sample set of six specimens of 12 months old ‘LOCK02’ plants grown in 8.5 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Haworthia plants which consisted of minimal overhead irrigation and regular fertilizer applications, and biological control measures against insect pests. Plants were grown under shade and no photoperiodic treatments or artificial light was given to the plants.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘LOCK02’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
A botanical description of ‘LOCK02’ and a comparison with the parent and closest known comparator is provided below.
