hybrid plant named ‘BBARE’

Abstract

‘BBARE’ is a distinctive variety of Rosa hybrid which is characterized by the combination of a shrubby growth habit, a medium plant size, canes with few thorns, a recurrent bloom habit with moderate to strong bloom fragrance, a double-petal flower with a high petal count, a near-white flower color at anthesis, as well as the stability and uniformity of traits through successive cycles of 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 Rosa hybrid.

Variety denomination: The inventive variety of Rosa hybrid disclosed herein has been given the variety denomination ‘BBARE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Rosa hybrid, shrub rose cultivar, which has been given the variety denomination of ‘BBARE’.

Parentage: The new Rosa hybrid cultivar ‘BBARE’ originated as a naturally occurring, partial-plant mutation of Rosa hybrid ‘Belinda's Dream’ (unpatented). Said mutation was initially discovered by the inventor in March of 2014 in a cultivated field of the parent plant at the inventor's commercial nursery in Brenham, Tex. The inventor observed one cane of an individual ‘Belinda's Dream’ plant which was producing near-white flowers instead of the characteristic medium pink flowers of ‘Belinda's Dream’. At that time, three stem cuttings were taken from the cane that was producing the white flowers. The resulting plants were isolated for further observation and to confirm uniformity and stability of the distinguishing characteristic. Subsequent cuttings were taken from these three plants which yielded a consistent crop of white-blooming plants. The new cultivar was given the name ‘BBARE’ in November of 2014.

Asexual Reproduction: ‘BBARE’ was first asexually propagated by vegetative cuttings in March of 2014 at a commercial nursery in Brenham, Tex. under the control of the inventor and has since been vegetatively propagated through one additional generation. The distinctive characteristics of the inventive ‘BBARE’ variety are stable from generation to generation; plants of the variety produced by asexual reproduction maintain the distinguishing characteristics of the original plant.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Rosa hybrid cultivar ‘BBARE’. These traits in combination distinguish ‘BBARE’ as a new and distinct cultivar.

• • 1 Rosa hybrid ‘BBARE’ exhibits a shrubby growth habit; and
  • 2. Rosa hybrid ‘BBARE’ exhibits a medium plant size; and
  • 3. Rosa hybrid ‘BBARE’ exhibits canes with few thorns; and
  • 4. Rosa hybrid ‘BBARE’ exhibits a recurrent bloom habit with moderate to strong flower fragrance; and
  • 5. Rosa hybrid ‘BBARE’ exhibits a double-type flower; and
  • 6. Rosa hybrid ‘BBARE’ exhibits a near-white perianth color, at anthesis.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Rosa hybrid known as ‘BBARE’, based upon observations of a plant, approximately 2 years old, grown outdoors, in full sun, at a commercial nursery in Brenham, Tex. Said plant was maintained with slow-release granular fertilizer and regularly watered with overhead irrigation. No artificial light, photoperiodic treatments, or chemical treatments were given to the plants. Observation data was recorded in November of 2014.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘BBARE’ 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, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 1986 edition.
