plant named ‘X5’

Abstract

A new cultivar of Aloe, ‘X5’, characterized by its vigorous growth habit, its short and compact plant habit, its abundance of inflorescences on strong erect scapes, and its flowers that are greenish white in color and emerge from red-orange flower buds, which gives the inflorescence a strong bicolor appearance.

Description

Botanical classification: Aloe hybrid.

Varietal denomination: ‘X5’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Aloe of hybrid origin, botanically known as Aloe ‘X5’ and will be referred to hereafter by its cultivar name, ‘X5’. ‘X5’ is a new cultivar of flowering Aloe grown for landscape and container use.

The new cultivar was derived from a controlled breeding program establish by the Inventor at his nursery in Linbro Park, Republic of South Africa in 1973. The overall purpose of the breeding program is to make selections of hybrid Aloe with desirable horticultural characteristics to include improved vigor, flowering ability, and disease resistance. ‘X5’ was selected in the Inventor's trial bed in June 2006 as a single unique plant from amongst the seedlings derived from a cross made in 2005 between unnamed complex hybrids in the Inventor's breeding program as the female parent and male parents.

Asexual reproduction of the new cultivar was first accomplished by offshoots by the Inventor in Linbro Park, Republic of South Africa in 2006. The characteristics of this cultivar have been determined both by offshoots and in vitro propagation to be stable and to reproduce 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 of Aloe. These attributes in combination distinguish ‘X5’ from all other selections of Aloe known to the Inventor.

• • 1. ‘X5’ exhibits a vigorous growth rate.
  • 2. ‘X5’ exhibits a short and compact plant habit.
  • 3. ‘X5’ produces an abundance of inflorescences on strong erect scapes.
  • 4. ‘X5’ exhibits flowers that are greenish white in color and emerge from red-orange flower buds forming a bicolored inflorescence.
    ‘X5’ can be distinguished from its parent plants. ‘X5’ differs from its female parent, in having a faster growth rate and in producing more inflorescences. ‘X5’ differs from its male parent in having a shorter and more compact plant habit and in producing flowers that are more intense in color. ‘X5’ can be most closely compared to another complex hybrid from the Inventor's breeding program, Aloe ‘ANDHOGP’ (not patented). ‘X5’ differs from ‘ANDHOGP’ in having straighter and narrower leaves with less distinct margins and in having red-orange to greenish white flowers on a bicolored inflorescence rather than a mono colored inflorescence with dull reddish pink flowers.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Aloe. The photographs were taken of a 2 year-old plant as grown outdoors in 3-liter containers in North West Province, Republic of South Africa.

The photograph in FIG. 1 illustrates the overall habit and appearance of ‘X5’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘X5’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Aloe.

DETAILED BOTANICAL DESCRIPTION

The detailed botanical data describes two-year old plants of ‘X5’ as grown in three-liter containers outdoors in North West Province, Republic of South Africa. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determinations are in accordance with The 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
