Title: Bougainvillea Plant Named ‘Kasumi’

Applicant: Masahiro Nakano

Filed: Concurrently with this application U.S. Plant patent application Ser. No 12/798,015

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bougainvillea plant, botanically known as Bougainvillea×hybrida and hereinafter referred to by the name ‘Sasara’.

The new Bougainvillea plant is a naturally-occurring branch mutation of a proprietary selection of Bougainville×hybrida known as ‘Konatu’, not patented. The new Bougainvillea plant was discovered and selected by the Inventor on a single flowering plant within a population of plants of ‘Konatu’ in a controlled greenhouse environment in Tsushima-shi, Aichi, Japan in May, 2005.

Asexual reproduction of the new Bougainvillea plant by cuttings in a controlled greenhouse environment in Tsushima-shi, Aichi, Japan since September, 2007, has shown that the unique features of this new Bougainvillea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Bougainvillea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Sasara’. These characteristics in combination distinguish ‘Sasara’ as a new and distinct cultivar of Bougainvillea:

- 1. Compact, upright and mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Relatively small leaves.
- 4. Freely flowering habit.
- 5. Pale pink-colored flower bracts.
- 6. Good garden performance.

Plants of the new Bougainvillea differ from plants of the parent, ‘Konatu’, primarily in flower bract color as plants of ‘Konatu’ have red purple-colored flowers.

Plants of the new Bougainvillea can be compared to plants of Bougainvillea×hybrida ‘Kasumi’, disclosed in a U.S. Plant patent application Ser. No. 12/798,015. Plants of the new Bougainvillea and ‘Sasara’ differ primarily in flower bract color as plants of the new Bougainvillea have lighter colored flower bracts.

Plants of the new Bougainvillea can also be compared to plants of Bougainvillea×buttiana ‘Mrs. Butt’, not patented. In side-by-side comparisons conducted in Tsushima-shi, Aichi, Japan, plants of the new Bougainvillea and ‘Mrs. Butt’ differed in the following characteristics:

- 1. Plants of the new Bougainvillea were more compact than and not as vigorous as plants of ‘Mrs. Butt’.
- 2. Plants of the new Bougainvillea were more upright than and not as outwardly spreading and trailing as plants of ‘Mrs. Butt’.
- 3. Plants of the new Bougainvillea had shorter internodes than plants of ‘Mrs. Butt’.
- 4. Plants of the new Bougainvillea were spineless whereas plants of ‘Mrs. Butt’ had spines.
- 5. Plants of the new Bougainvillea had smaller leaves than plants of ‘Mrs. Butt’.
- 6. Plants of the new Bougainvillea had smaller inflorescences and flowers than plants of ‘Mrs. Butt’.
- 7. Plants of the new Bougainvillea and ‘Mrs. Butt’ differed in flower bract color as plants of ‘Mrs. Butt’ had red purple-colored flower bracts.
- 8. Plants of the new Bougainvillea had shorter peduncles than plants of ‘Mrs. Butt’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Bougainvillea plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Bougainvillea plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sasara’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sasara’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 12-cm containers during the early autumn in a polyethylene-covered greenhouse in Tsushima-shi, Aichi, Japan and under commercial practice with day temperatures ranging from 20° C. to 40° C. and night temperatures averaging 20° C. Plants were six months old when the description and photographs were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
