plant named ‘AUEMB’

Abstract

A new cultivar of Begonia plant named ‘AUEMB’ that is characterized by pink flowers and large leaves that are orange on the upper-side and red-orange on the under-side.

Description

Botanical classification: Begonia hybrid.

Variety denomination: ‘AUEMB’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant botanically known as Begonia hybrid and hereinafter referred to by the cultivar name ‘AUEMB’.

‘AUEMB’ originated from the crossing of the female or seed parent Begonia ‘Angel Glow’ (not patented) and the male or pollen parent Begonia ‘Marmaduke’ (not patented). The crossing was conducted in 2012 in Danielson, Conn. The resulting seeds were subsequently planted and grown. The cultivar ‘AUEMB’ was selected by the inventor in 2013 in a controlled environment as a single plant within the progeny of the stated cross in a cultivated area of Danielson, Conn.

Asexual reproduction of the new cultivar ‘AUEMB’ first occurred by tissue culture in 2013 in Danielson, Conn. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Begonia cultivar ‘AUEMB’. These traits in combination distinguish ‘AUEMB’ as a new and distinct cultivar apart from other existing known varieties of Begonia.

• • 1. Begonia ‘AUEMB’ exhibits large leaves.
  • 2. Begonia ‘AUEMB’ exhibits leaves that are orange on the upper-side and red-orange on the under-side.
  • 2. Begonia ‘AUEMB’ exhibits pink flowers.

The closest comparison cultivar is Begonia ‘Northern Lights’ (not patented). ‘AUEMB’ is distinguishable from ‘Northern Lights’ by the following characteristics:

• • 1. Begonia ‘AUEMB’ exhibits smaller leaves than the leaves of ‘Northern Lights’.
  • 2. Begonia ‘AUEMB’ exhibits leaves that are orange on the upper-side and red-orange on the under-side. In contrast, the leaves of ‘Northern Lights’ are yellow-green and speckled with red blotches on both sides.
  • 3. Begonia ‘AUEMB’ exhibits veins on the under-side of the leaf that are smooth. The leaf veins on the under-side of the leaves of ‘Northern Lights’ have red hairs.
  • 4. Begonia ‘AUEMB’ exhibits pink flowers. The flowers of ‘Northern Lights’ are white.

‘AUEMB’ is distinguishable from the female or seed parent Begonia ‘Angel Glow’ by the following characteristics:

• • 1. Begonia ‘AUEMB’ exhibits larger leaves than the leaves of ‘Angel Glow’.
  • 2. Begonia ‘AUEMB’ exhibits leaves that are orange on the upper-side and red-orange on the under-side. In contrast, the leaves of ‘Angel Glow’ are red-orange with green veins on both sides.
  • 3. Begonia ‘AUEMB’ exhibits a larger overall plant height than the overall plant height of ‘Angel Glow’.

‘AUEMB’ is distinguishable from the male or pollen parent Begonia ‘Marmaduke’ by the following characteristics:

• • 1. Begonia ‘AUEMB’ exhibits smaller leaves than the leaves of ‘Marmaduke’.
  • 2. Begonia ‘AUEMB’ exhibits leaves that are orange on the upper-side and red-orange on the under-side. The upper-side leaves are smooth with no hairs. In contrast, the leaves of ‘Marmaduke’ are red-orange, undulating and the upper-side is covered with fine hairs.
  • 3. Begonia ‘AUEMB’ exhibits a smaller overall plant height than the overall plant height of ‘Marmaduke’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographs illustrate the distinguishing traits of Begonia ‘AUEMB’.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Begonia cultivar named ‘AUEMB’. Data was collected in Danielson, Conn. from 2 year old greenhouse grown plants outdoors in 6 inch diameter containers. The time of year was Summer and the average temperature was 23 degrees Centigrade during the day and 18 degrees Centigrade at night. No photoperiodic treatments or growth retards were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘AUEMB’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
