Description

Latin name of the genus and species: Ipomoea batatas (L.) Lam.
Variety denomination: ‘NCORNSP-011MNLC’.
BACKGROUND OF THE INVENTION
Ipomoea batatas is a member of the morning glory family Convolvulaceae. The cultivated members of Ipomoea batatas are commonly produced for consumption of their enlarged storage roots and they are commonly referred to as the white or yellow sweetpotato and the orange yam. The plants of the edible sweetpotato types are typically fast-growing, green vines possessing a wide variety of leaf shapes ranging from palmate and deeply lobed, to cordate or triangular shaped leaves with no lobes. Ornamental sweetpotatoes, which have been bred and selected for their unique foliage colors, leaf shapes, and plant habits, typically do not produce large fleshy storage roots like the sweetpotato cultivated for consumption. The storage roots produced by ornamental sweetpotatoes are typically not as large because no selection has been exercised for yield, thus storage roots do not begin to swell until very late in the season and those that are produced are not very attractive.
Like their cultivated forms, ornamental sweetpotato plants are a heat loving, drought tolerant vine grown as an annual, but they possess unique foliage colors, leaf shapes, and growth habits, which have significant value in the ornamental marketplace. They are highly desirable in the landscape and ornamental industries because their foliage comes in a wide variety of colors and shapes. Also, they can be grown in a potted plant and/or mixed planting format, and they have the ability to cover a large space or hang over walls and pots creating brightly colored and textured backdrops in gardens and patios. Most ornamental sweetpotatoes grow and last the entire growing season and they require little maintenance. Moreover, these plants have few insect or disease problems.
Until the release of the Sweet Caroline series of ornamental sweetpotatoes (see below) there were six popular types of ornamental sweetpotatoes, cultivated primarily as annual, summer vines in landscaping applications. These six cultivars are: ‘Blackie’ (unpatented), having purple foliage and lavender flowers; ‘Terrace Lime’ (unpatented) and ‘Margarita’ (unpatented; also known as ‘Sulfur’), which have large brilliant chartreuse leaves and lavender blooms; ‘Black Heart’ (unpatented; also known as ‘Ace of Spades’), having heart-shaped leaves with burgundy purple color; ‘Tricolor’ (unpatented; also known as ‘Pink Frost’), a variegated plant having pale green, white, and pink-margined leaves; and ‘Lady Fingers’ (unpatented), which has medium green, dainty leaves divided into long, thin, finger-like lobes which are complemented by burgundy stems and veins.
To meet the growing horticultural demand for ornamental sweetpotatoes it is desirable to produce new cultivars of ornamental sweetpotato with attractive foliage colors, leaf shapes, and plant architectures. In addition, it would be advantageous to develop cultivars of ornamental sweetpotato exhibiting a more compact growth, and which do not out-compete other species in mixed containers.
‘NCORNSP-011MNLC’ was bred to meet the increasing demand for new ornamental sweetpotatoes and this plant patent application describes this new and distinct invention. ‘NCORNSP-011MNLC’ is a very compact, semi-upright, densely-mounding plant producing many short shoots. It is distinguishable from other cultivars by its dark purple leaves that have 5-7 extremely deep lobes, a very compact habit and erect mounding plant architecture. The extremely deep-lobed feature of the leaves of this plant and the plant architecture is what makes ‘NCORNSP-011MNLC’ unique amongst the current ornamental sweetpotatoes in the marketplace. ‘NCORNSP-011MNLC’ also exhibits very good vigor and is very well-branched.
In greenhouse and field trials conducted since 2005 by the breeding program and industry collaborators ‘NCORNSP-011MNLC’ has been shown to be much less vigorous than Ipomoea batatas ‘Margarita’ and ‘Blackie’ and is suitable for use as a landscape or containerized plant. The production of flowers by ‘NCORNSP-011MNLC’ is rare even under short day conditions.
‘NCORNSP-011MNLC’ originated from open-pollinated seed harvested from the breeding clone ‘NC1650-009N’ (the female parent; unpatented). These botanical seed were harvested from our winter greenhouse crossing blocks between September of 2003 and April of 2004 in North Carolina. Botanical seed from this half-sib family were planted in the greenhouse during the spring of 2005. The first cycle of selection on the population was exercised in the seedling trays and survivors were transferred to a single 6-inch pot, which was then maintained in the greenhouse. Cuttings (2 each) were taken from the plants in April and planted at a research station in North Carolina as 2-plant un-replicated plots during late June to early July 2005. A single, individual clone, now known as ‘NCORNSP-011MNLC’ was selected Sep. 1, 2005 because of its combination of exceptional ornamental sweetpotato features, and has been propagated asexually since that time.
Since its selection, Ipomoea batatas ‘NCORNSP-01MNLC’ has been asexually reproduced at a greenhouse in North Carolina predominantly by vegetative propagation of vine cuttings. Successively, there have been four cycles of vegetative propagation, one cycle of tissue culture micro propagation, and multiple vegetative propagation cycles to increase the plant population. Asexual reproduction of ‘NCORNSP-01MNLC’ by vine cuttings has shown that the unique features of the new cultivar are stable and the plant reproduces true to type in successive generations of asexual reproduction.
REFERENCE TO PLANT BREEDERS RIGHTS
Plant Breeders Rights for ‘NCORNSP-011MNLC’ have been applied for in Canada in October 2009. ‘NCORNSP-011MNLC’ has not been made publicly available or sold more than one year prior to the date of this application.
SUMMARY OF THE INVENTION
‘NCORNSP-011MNLC’ is a very compact, semi-upright, densely-mounding plant producing many short shoots. It is distinguishable from other cultivars by its dark purple leaves that have 5-7 extremely deeply lobed leaves, a very compact habit and erect mounding plant architecture. The extremely deep-lobed feature of the leaves of this plant and the plant architecture is what makes ‘NCORNSP-011MNLC’ unique amongst the current ornamental sweetpotatoes in the marketplace. ‘NCORNSP-011MNLC’ also exhibits very good vigor and is very well branched. It is less vigorous than Ipomoea batatas ‘Margarita’ and ‘Blackie’ and is well suited for production as a landscape or containerized plant. The production of flowers by ‘NCORNSP-011MNLC’ is rare even under short day conditions.

DESCRIPTION OF THE NEW VARIETY
The following is a detailed description of the botanical characteristics of a new and distinct variety of Ipomoea batatas plant known by the variety name Ipomoea batatas ‘NCORNSP-011MNLC’. All colors cited herein refer to The Royal Horticultural Society Colour Chart (The Royal Horticultural Society, London, 1995, 4th ed.) designations except where general terms of ordinary dictionary significance are used. Where dimensions, sizes, colors, and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable.
The descriptions reported herein are from 68-day-old specimens grown individually in six-inch “azalea” pots. The plants were grown in Raleigh, N.C., under commercial practice in a glass-covered greenhouse where, during the spring, day and night temperatures range between 18-30° C. and 15-21° C., respectively. Plant descriptions were taken in June 2009. Ipomoea batatas ‘NCORNSP-011MNLC’ has not been observed under all possible environmental conditions; therefore, the phenotype may vary with variations in the environment such as season, temperature, light intensity, day length, cultural conditions, and the like.
