tree named ‘Ingram's red’

Abstract

A new cultivar of Swietenia mahagoni named ‘Ingram's Red’, characterized by its foliage on new wood that is dark burgundy to maroon in color, its small leaves with red petioles and rachis, its leaflets that have red petiolules and red midrib veins, its new wood that is red in color, and its dwarf growth habit.

Description

Botanical classification: Swietenia mahagoni.

Variety denomination: ‘Ingram's Red’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Swietenia mahagoni, and will be referred to hereafter by its cultivar name, ‘Ingram's Red’. ‘Ingram's Red’ is a new cultivar of West Indies mahagony tree grown for use as a landscape plant.

The new cultivar of Swietenia, ‘Ingram's Red’, was discovered by the Inventor in spring of 1996 in Homestead, Fla. as a naturally occurring whole plant mutation. ‘Ingram's Red’ was discovered in a nursery bed of seedlings derived from seed of unnamed plants of Swietenia mahagoni.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings by the Inventor in Homestead, Fla. in May 2000. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as grown outdoors in Homestead, Fla. These attributes in combination distinguish ‘Ingram's Red’ as a unique cultivar of Swietenia.

• • 1. ‘Ingram's Red’ exhibits foliage on new wood that is dark burgundy to maroon in color.
  • 2. ‘Ingram's Red’ exhibits leaves that are smaller in size than is typical of the species.
  • 3. ‘Ingram's Red’ exhibits leaves that have red petioles and rachis.
  • 4. ‘Ingram's Red’ exhibits leaflets that have red petiolules and red midrib veins.
  • 5. ‘Ingram's Red’ exhibits new wood that is red in color.
  • 6. ‘Ingram's Red’ exhibits a dwarf growth habit.

Plants of parental species, Swietenia mahagoni, differ from ‘Ingram's Red’ in having green foliage and new wood and in lacking any red coloration in its foliage and wood. In addition, ‘Ingram's Red’ has a dwarf plant habit in comparison. There are no other cultivars of Swietenia mahagoni known to the Inventor.
