Ipomoea plant named ‘IP059’

Abstract

A new and distinct cultivar of Ipomoea plant named ‘IP059’, characterized by its compact and mounding growth habit; freely branching plant habit; relatively small deeply dissected light green-colored foliage; and pink-colored flowers.

Description

Botanical designation: Ipomoea batatas.

Cultivar denomination: ‘IP059’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ipomoea, botanically known as Ipomoea batatas, also known by the trade name Dwarf Marguerite Improved and hereinafter referred to by the name ‘IP059’.

The new Ipomoea is a product of a planned breeding program conducted by the Inventor in Riverhead, N.Y. The objective of the breeding program is to create new compact Ipomoea cultivars with attractive foliage shape and coloration.

The new Ipomoea originated from a cross-pollination made by the Inventor on Nov. 11, 2001 in Riverhead, N.Y. of the Ipomoea batatas cultivar Blackie, not patented, as the female, or seed, parent with a pollen mixture collected from plants of the Ipomoea batatas cultivars Marguerite and Lady Fingers, both not patented, as the male, or pollen, parent. The new Ipomoea was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Riverhead, N.Y. on Jul. 14, 2004. The selection of this plant was based on its compact growth habit and attractive foliage shape and coloration.

Asexual reproduction of the new Ipomoea by terminal cuttings in a controlled environment in Riverhead, N.Y. since February, 2005, has shown that the unique features of this new Ipomoea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar IP059 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘IP059’. These characteristics in combination distinguish ‘IP059’ as a new and distinct cultivar of Ipomoea:

• • 1. Compact and mounding growth habit.
  • 2. Freely branching plant habit.
  • 3. Relatively small deeply dissected light green-colored foliage.
  • 4. Pink-colored flowers.

Plants of the new Ipomoea can be compared to plants of the female parent, the cultivar Blackie. Plants of the new Ipomoea differ from plants of the cultivar Blackie in the following characteristics:

• • 1. Plants of the new Ipomoea are much more compact and less vigorous than plants of the cultivar Blackie.
  • 2. Plants of the new Ipomoea have shorter internodes than plants of the cultivar Blackie.
  • 3. Plants of the new Ipomoea have smaller leaves than plants of the cultivar Blackie.
  • 4. Plants of the new Ipomoea have light green-colored foliage whereas plants of the cultivar Blackie have purple-colored foliage.

Plants of the new Ipomoea can be compared to plants of the pollen parents, the Ipomoea batatas cultivars Marguerite and Lady Fingers. Plants of the new Ipomoea differ primarily from plants of the cultivars Marguerite and Lady Fingers in leaf shape.

Plants of the new Ipomoea can also be compared to plants of the cultivar Sweet Carolina Light Green, disclosed in U.S. Plant Pat. No. 15,028. In side-by-side comparisons conducted in Riverhead, N.Y., plants of the new Ipomoea and the cultivar Sweet Carolina Light Green differed in the following characteristics:

• • 1. Plants of the new Ipomoea were more compact and less vigorous than plants of the cultivar Sweet Caroline Light Green.
  • 2. Plants of the new Ipomoea had smaller leaves than plants of the cultivar Sweet Caroline Light Green.
  • 3. Plants of the new Ipomoea produced flowers whereas plants of the cultivar Sweet Carolina Light Green did not produce flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Ipomoea, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ipomoea.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘IP059’ grown in a container.

The photograph on the second sheet comprises a close-up of typical leaves of ‘IP059’ (left) and ‘Blackie’ (right).

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Riverhead, N.Y. in a polyethylene-covered greenhouse during the spring and summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 20° C. to about 22° C., night temperatures were about 18° C. and light levels ranged from 3,000 to 8,000 foot-candle. Plants were about 14 weeks old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
