USPP20880P2 - Ipomoea plant named ‘Seki Blapalm’ - Google Patents

Abstract

A new Ipomoea plant named ‘Seki Blapalm’ particularly distinguished by compact and mounding plant habit that becomes more outwardly trailing with age, vigorous, freely branching with dense foliage, and very dark, almost black palmately lobed foliage, with soft purple-violet and white flowers.

Description

Latin name of the genus and species of the plant claimed: Ipomoea batatas (L.) Lam.

Varietal denomination: ‘Seki Blapalm’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Ipomoea, botanically known as Ipomoea batatas (L.) Lam, and commonly known as Ornamental Sweet Potato, and hereinafter referred to by the variety name ‘Seki Blapalm.’ These plants are grown, not for their flowers, but for their foliage and plant habit characteristics. These plants flower very rarely and then only under strict short day lengths. Each flower is ephemeral, in that it only lasts up to 24 hours, and blooms mostly through the night and early morning hours.

‘Seki Blapalm’ is a product of a planned breeding program. The new cultivar ‘Seki Blapalm’ has a compact and mounding plant habit that becomes more outwardly trailing with age, vigorous, freely branching with dense foliage, and very dark, almost black palmately lobed foliage, with soft purple-violet and white flowers.

‘Seki Blapalm’ originated from an open pollination in a controlled breeding program in Gilroy, Calif. USA. The female parent was ‘Sweet Caroline Purple’ (U.S. Plant Pat. No. 14,912). ‘Sweet Caroline Purple’ has a less compact plant habit, shorter petioles and lighter colored foliage than ‘Seki Blapalm.’ The male parent of ‘Seki Blapalm’ was unknown.

‘Seki Blapalm’ was selected as one flowering plant within the progeny of the stated cross in March 2007, in a controlled environment in Gilroy, Calif. USA. The pollination took place in July 2006 and the seed sown in December 2006.

The first act of asexual reproduction of ‘Seki Blapalm’ was accomplished when vegetative cuttings were taken from the initial selection in the March 2007 in a controlled environment in Gilroy, Calif. USA.

Horticultural examination of plants grown from cuttings of the plant initiated in March 2007 in Gilroy, Calif. USA, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Seki Blapalm’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Seki Blapalm’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Dec. 24, 2007. ‘Seki Blapalm’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF DRAWING

The accompanying photographic drawing shows typical foliage and plant habit characteristics of ‘Seki Blapalm’ with colors being as true as possible with an illustration of this type. The photographic drawing shows 3 potted plants of the new variety growing in a 14 inch container. These plants were grown and photographed in Gilroy, Calif. USA in the summer of 2008.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in October 2008 in Gilroy, Calif. USA on plants that were growing in 6 inch pots in a greenhouse. Culture of these plants started in about August 2008, when they came from sterile tissue culture tubes after laboratory micropropagation.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown in Gilroy, Calif. USA. The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Ipomoea as a new and distinct variety.
