Campsis plant named ‘HOMR’

Abstract

A new and distinct cultivar of Campsis plant named ‘HOMR’, characterized by its compact and vining growth habit; leaves, and stems with dense pubescence; freely flowering plant habit; long flowering period; large red-colored flowers arranged in large panicles; and good garden performance.

Description

Botanical designation: Campsis×tagliabuana.

Cultivar denomination: ‘HOMR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campsis, botanically known as Campsis×tagliabuana and hereinafter referred to by the name ‘HOMR’.

The new Campsis is a product of a planned breeding program conducted by the Inventors in Seneca, S.C. The objective of the breeding program is to create new Campsis cultivars with attractive plant form and flower coloration.

The new Campsis originated from a self-pollination made by the Inventors in 1990, in Seneca, S.C. of the Campsis×tagliabuana cultivar Madame Galen, not patented. The new Campsis was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated self-pollination in a controlled environment in Seneca, S.C. in 1993.

Asexual reproduction of the new Campsis by terminal cuttings in a controlled environment in Seneca, S.C. since August, 1995, has shown that the unique features of this new Campsis are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar HOMR 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 ‘HOMR’. These characteristics in combination distinguish ‘HOMR’ as a new and distinct cultivar of Campsis:

• • 1. Compact and vining growth habit.
  • 2. Leaves and stems with dense pubescence.
  • 3. Freely flowering plant habit.
  • 4. Long flowering period.
  • 5. Large red-colored flowers arranged in large panicles.
  • 6. Good garden performance.

Plants of the new Campsis can be compared to plants of the parent, the cultivar Madame Galen. Plants of the new Campsis differ from plants of the cultivar Madame Galen in the following characteristics:

• • 1. Plants of the new Campsis are not as spreading as and slower growing than plants of the cultivar Madame Galen.
  • 2. Leaves of plants of the new Campsis are pubescent whereas leaves of plants of the cultivar Madame Galen are glabrous.
  • 3. Plants of the new Campsis flower more freely and for a longer period of time than plants of the cultivar Madame Galen.
  • 4. Plants of the new Campsis have larger flowers than plants of the cultivar Madame Galen.
  • 5. Plants of the new Campsis rarely produce fruit whereas plants of the cultivar Madame Galen produce numerous fruits.

Plants of the new Campsis can be compared to plants of the cultivar Kudian, disclosed in U.S. Plant Pat. No. 13,139. In side-by-side comparisons conducted in Seneca, S.C., plants of the new Campsis differed from plants of the cultivar Kudian in the following characteristics:

• • 1. Plants of the new Campsis were more upright than and not as outwardly spreading as plants of the cultivar Kudian.
  • 2. Plants of the new Campsis had shorter internodes than plants of the cultivar Kudian.
  • 3. Upper leaf surfaces of plants of the new Campsis were pubescent whereas upper leaf surfaces of plants of the cultivar Kudian were glabrous.
  • 4. Plants of the new Campsis flowered earlier and more freely than plants of the cultivar Kudian.
  • 5. Plants of the new Campsis had larger flowers than plants of the cultivar Kudian.
  • 6. Flower color of plants of the new Campsis was red whereas flower color of plants of the cultivar Kudian was orange red.
  • 7. Plants of the new Campsis rarely produced fruit whereas plants of the cultivar Kudain produced numerous fruits.

Plants of the new Campsis can be also compared to plants of the cultivar Crimson Trumpet, not patented. In side-by-side comparisons conducted in Seneca, S.C., plants of the new Campsis differed from plants of the cultivar Crimson Trumpet in the following characteristics:

• • 1. Plants of the new Campsis were more compact than plants of the cultivar Crimson Trumpet.
  • 2. Leaves of plants of the new Campsis were pubescent whereas leaves of plants of the cultivar Crimson Trumpet were glabrous.
  • 3. Plants of the new Campsis flowered earlier than plants of the cultivar Crimson Trumpet.
  • 4. Flower color of plants of the new Campsis was red whereas flower color of plants of the cultivar Crimson Trumpet was dark red.
  • 5. Plants of the new Campsis rarely produced fruit whereas plants of the cultivar Crimson Trumpet produced numerous fruits.
