Mandevilla plant named ‘Sunmandecrim’

A new and distinct variety of Mandevilla plant is provided that was created through controlled cross-breeding. The female parent is a seedling of Mandevilla atroviolacea and the male parent is a Mandevilla amabilis×boliviensis ‘Sunmandeho’ plant. The new variety exhibits a lianous growth habit and well tolerates heat. Attractive deep red flowers having a brilliant orange inside throat are formed over an extended period of time. The flower petals curve outwards. Moderate olive green leaves having smooth surface and an entire margin are formed. The leaf surface is smooth. Plants of the new variety are well suited for growing in pots that are equipped with a support for climbing.

Description

Botanical classification: Mandevilla atroviolacea×(Mandevilla amabalis×boliviensis).

Variety denomination: ‘Sunmandecrim’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Mandevilla plant obtained from crossing a seedling of an unnamed Mandevilla atroviolacea plant (female) and a Mandevilla amabilis×boliviensis ‘Sunmandeho’ plant (male).

The Mandevilla is a popular plant and is used as a pot plant in the summer season or an indoor plant or a glasshouse plant. Only a limited number of varieties of Mandevilla plants are commercially available. Accordingly, this invention was aimed at obtaining a new variety having a large flower with deep red petals, and a long flowering duration.

In September 1997, crossing with a seedling of Mandevilla atroviolacea and Mandevilla plant ‘Sunmandeho’ (U.S. Plant Pat. No. 11,556) was conducted. From that crossing, 40 seedlings were obtained. Those seedlings were grown in a greenhouse from April 1998, and only one seedling was selected in August 1999. The selected plant was propagated by cutting and then grown in bed and pot on trial from August 1999 to November 2000. The botanical characteristics of the plant were examined, using similar variety ‘Sunmandeho’ and ‘Rose Giant’ (non-patented in the United States), for comparison. As a result, it was concluded that this new Mandevilla plant is distinguishable from any other variety, whose existence is known to us, and is uniform and stable in its characteristics. This new variety of Mandevilla plant was named ‘Sunmandecrim’. The new variety reproduces true to type in successive generations of asexual reproduction.

In the following description, the color-coding is in accordance with the R.H.S. Colour Chart of The Royal Horticultural Society, London, England.

The female parent in the obtaining of this new variety ‘Sunmandecrim’ is a seedling of Mandevilla atroviolacea (non-patented in the United States).
