Abstract
A new and distinct Ilex verticillata plant named ‘B-1-17’ which is characterized by vigorous growth, an abundance of strong upright main stems, very short lateral branches with each bearing an abundance of large vibrant red berries borne along their entire length. The claimed plant propagates successfully by softwood stem cuttings and has proven to be uniform and stable in the resulting generations.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Ilex verticillata.
Variety denomination: The inventive variety of Ilex verticillata disclosed herein has been given the variety denomination ‘B-1-17’.
The present invention relates to a new and distinct variety of Ilex verticillata, which has been given the denomination, ‘B-1-17’. Ilex verticillata, known commonly as winterberry, is a deciduous perennial that is widely cultivated for its ornate berries born along the lateral branches. The berries persist for many months through fall and winter, making it an ideal plant for ornamental landscaping in its hardiness range and also for the cut flower industry.
Parentage: The new cultivar ‘B-1-17’ is a seedling selection resulting from the open pollination of Ilex verticillata ‘KK-10’ (not patented), the seed parent, and an undesignated male Ilex verticillata plant, the pollen parent. In 2010, seeds were harvested from ‘KK-10’ which resulted in 252 seedlings. In March of 2011, the seedlings were transplanted into a field in Willow Creek, Calif. and grown to a mature size. From 2011 to 2014, these plants were evaluated for commercial production, based on criteria such as growth habit and fruiting habit. In September of 2014, one plant was observed which exhibited many main stems bearing large, vibrant red berries borne all along the very short lateral branches and berries which matured earlier than the parents and other progeny. This new plant was given the breeder denomination, ‘B-1-17’.
Asexual Reproduction: In the summer of 2017, ‘B-1-17’ was first asexually reproduced in Willow Creek, Calif. by way of softwood stem cuttings taken from one year old growth. The claimed plant was found to asexually reproduce in uniform and stable manner and four successive cycles of vegetative propagation have proven to be true to type.
The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Ilex verticillata cultivar ‘B-1-17’. These traits, in combination, distinguish ‘B-1-17’ as a new and distinct cultivar.
-
- 1. ‘B-1-17’ exhibits excellent plant vigor and a fast rate of growth; and
- 2. ‘B-1-17’ exhibits a large quantity of strong and upright main stems; and
- 3. ‘B-1-17’ exhibits very short lateral branches; and
- 4. ‘B-1-17’ exhibits a large quantity of berries born along the entire length of the lateral branches, including the distalmost portion of the lateral branches usually devoid of berries in the species, which negates the need for manual pruning or use of plant growth regulators; and
- 5. ‘B-1-17’ exhibits large, vibrant red berries.
The FIGURE illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary four and a half year old field-grown ‘B-1-17’ plant in Willow Creek, Calif.
The following is a detailed botanical description of a new and distinct variety of a Ilex verticillata known as ‘B-1-17’. Plant observations were made on field grown plants produced in Willow Creek, Calif. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made of a mature ‘B-1-17’ plant, transplanted into a loamy clay field on May 1, 2018, as a one-year-old rooted cutting grown in a 4-inch nursery pot. The plant was grown in full sun and was provided a combination of overhead and drip irrigation. Fertilizer was regularly applied using a fertigation technique, and the plant was occasionally treated for mites when required. In March of 2019 and again in the fall of 2020, the plant was pruned to 7 cm above soil level and have since been allowed to grow without further pruning. Observation data was recorded in early October of 2022. Observation data were recorded in the late May of 2022 with the exception of the berries which were recorded in early October of 2022.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, younger plants. ‘B-1-17’ 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.
