plant named ‘Orange Chocolate’

Abstract

A new and distinct cultivar of Canna plant named ‘ORANGE CHOCOLATE’ that is characterized by dwarf habit, olive green to purple brown foliage, and bright orange flowers which are open faced and attractively arranged within the inflorescence. In combination these traits set ‘ORANGE CHOCOLATE’ apart from all other varieties of Canna known to the inventor.

Description

Genus: CANNA.

Species: ×generalis.

Denomination: ‘ORANGE CHOCOLATE’.

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application No. 61/270,789 filed on Jul. 14, 2009, entitled Canna Plant Named ‘ORANGE CHOCOLATE’.

This application is co-pending with the application of same filing date for the inventor'variety of Canna plant named ‘CHOCOLATE SUNRISE’ (U.S. Plant patent application Ser. No. 12/803,914).

The present invention relates to a new and distinct cultivar of Canna, also known as Canna Lily or Indian Shot, which is grown as an ornamental annual or perennial, according to climate zone, for use in planted containers and in the garden and landscape. The new cultivar is known botanically as Canna×generalis, and will be referred to hereinafter by the cultivar name ‘ORANGE CHOCOLATE’.

The inventor has carried out a Canna breeding program at the inventor's nursery in Kibbutz Saad, Israel since 2005. The breeding program is aimed at producing new varieties of Canna with useful commercial characteristics: primarily new varieties which exhibit a dwarf habit with colorful foliage and bearing well-presented flowers. ‘ORANGE CHOCOLATE’ arose and was selected by the inventor in 2006 as an open pollinated seedling whose male parent is unknown and whose female parent is Canna ‘Wine and Roses’ (unpatented). The inventor used this same parentage to develop the inventor's co-pending variety ‘CHOCOLATE SUNRISE’. Both co-pending varieties exhibit almost identical habit and foliage color. However, the flowers of ‘ORANGE CHOCOLATE’ are bright orange in color, whereas the flowers of ‘CHOCOLATE SUNRISE’ are deep yellow in color.

‘ORANGE CHOCOLATE’ was first asexually reproduced by the inventor in Kibbutz Saad, Israel in 2006. Asexual propagation was accomplished by division of the rhizome. Since that time, under careful observation, the distinguishing characteristics of ‘ORANGE CHOCOLATE’ have been determined stable and uniform, and to reproduce true to type in successive generations of asexual propagation.

The variety of Canna which is considered by the inventor to most closely resemble ‘ORANGE CHOCOLATE’ is the parent plant, Canna ‘Wine and Roses’. ‘Wine and Roses’ and ‘ORANGE CHOCOLATE’ both exhibit dark olive green to purple brown colored foliage. However, the flowers of ‘Wine and Roses’ are rose pink in color whereas the flowers of ‘ORANGE CHOCOLATE’ are bright orange in color.

SUMMARY OF THE INVENTION

The distinguishing characteristics of ‘ORANGE CHOCOLATE’ are as follows: In combination these traits set ‘ORANGE CHOCOLATE’ apart from all other existing varieties of CANNA known to the inventor. ‘ORANGE CHOCOLATE’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions.

• • 1. ‘ORANGE CHOCOLATE’ grows and remains short in height.
  • 2. After one year of growth, a plant of ‘ORANGE CHOCOLATE’ achieves a height of approximately 75 cm-120 cm and a spread of 50 cm-70 cm.
  • 3. ‘ORANGE CHOCOLATE’ bears bright orange flowers.
  • 4. The flowers of ‘ORANGE CHOCOLATE’ are open faced and attractively arranged within the inflorescence.
  • 5. The foliage of ‘ORANGE CHOCOLATE’ is dark olive green to purple brown in color.

DETAILED BOTANICAL DESCRIPTION

In the following botanical description, all color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.

The plants used for this botanical description were grown from rhizomes which the inventor shipped from his nursery at Kibbutz Saad, Israel to Santa Barbara, Calif. The rhizomes were planted in the ground in August 2010. The observed plants were twelve months of age.

• Botanical classification: CANNA×generalis ‘ORANGE CHOCOLATE’.
• Parentage: Open pollination between unknown male parent and Canna ‘Wine and Roses’ as female parent.
• Propagation: By division of field-grown rhizomes or by division of tissue cultured plants.
• Cultural suggestions: In common with Cannas generally, ‘ORANGE CHOCOLATE’ is evergreen in warm climates, but will die back as winter approaches in cool climates. Rhizomes may be mulched to protect from light frost but should be lifted and stored if the ground is liable to freeze below the surface.
• Hardiness: ‘ORANGE CHOCOLATE’ is evergreen in USDA Zone 8.
