Abstract
A new and distinct Escallonia hybrid plant named ‘IB411-6’ which is characterized by a compact, densely-foliaged growth, relatively small foliage, pure white flowers, and the stability of these characteristics from generation to generation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Escallonia hybrid.
Variety denomination: The inventive variety of Escallonia hybrid disclosed herein has been given the variety denomination ‘IB411-6’.
Parentage: ‘IB411-6’ is a hybrid seedling selection resulting from the controlled pollination of Escallonia exoniensis ‘Fradesii Nana’ (not patented), the seed parent, with an unnamed white-flowered form of Escallonia sp. ‘Iveyi’ (not patented), the pollen parent. A controlled breeding program was undertaken at the inventors' commercial plant nursery in Wonga Park, Victoria, Australia with the goal of developing a range of Escallonia hybrids that exhibited small foliage size, varying flower colors and densely foliaged growth habits. As part of the breeding program, controlled pollination took place in the summer of 2010-2011. Seed was collected from said cross and subsequently sown in June 2011. The resulting seedlings were grown to flowering maturity in the summer of 2012. At that time, fourteen selections were made and further grown on in the field for evaluation. Cuttings were also taken from each selection for container production trials. In February of 2015, one seedling was observed which exhibited small foliage, a compact and densely foliaged growth habit with white flowers. The seedling was isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘IB411-6’ was selected for commercialization.
Asexual Reproduction: ‘IB411-6’ was first asexually reproduced by way of softwood stem cuttings in the summer of 2012 at the inventor's nursery in Wonga Park, Victoria, Australia. Through seven subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Escallonia cultivar, ‘IB411-6’. These traits, in combination, distinguish ‘IB411-6’ as a new and distinct cultivar.
-
- 1. ‘IB411-6’ exhibits a short plant height and a densely-foliaged growth habit; and
- 2. ‘IB411-6’ exhibits an abundance of relatively small foliage; and
- 3. ‘IB411-6’ exhibits an abundance of pure white flowers.
The following is a detailed botanical description of a new and distinct variety of a Escallonia hybrid plant known as ‘IB411-6’. Plant observations were made on plants grown in Wonga Park, Victoria, Australia. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made from 1 year old ‘IB411-6’ plants grown outdoors in 2 liter nursery containers. Plants were grown under full sun exposure, fertilized with a slow release granular fertilizer product, and were regularly watered with overhead irrigation. Temperatures ranged between 13 and 28 degrees Celsius during the day and 3 to 11 degrees Celsius at night. No pest and disease measures were taken. Observation data were recorded in October of 2019.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, younger plants. ‘IB411-6’ 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 vary with variations in the environment such as season, temperature, light intensity, day length, cultural conditions and the like. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 1986 edition except where common terms of color are used.
