plant named ‘Starlight’

Abstract

A new cultivar of Anthericum ‘Starlight’ that is characterized by its variegated foliage with light yellow-green and creamy-white midribs, and multiple longitudinal stripes throughout the darker green leaf blade, its yellow-green inflorescence stalks and its ust growth habit, golden yellow colored flower buds, white flowers with yellow tips and bright yellow stamens, and its non-viable seeds.

Description

Botanical classification: Anthericum saundersiae.

Varietal denomination: ‘Starlight’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthericum saundersiae and will be referred to hereafter by its cultivar name, ‘Starlight’. The new cultivar of Anthericum lily grass is a new herbaceous perennial grown for container and landscape use.

The new cultivar, ‘Starlight’ arose as a naturally occurring shoot mutation on an unnamed and unpatented plant of Anthericum saundersiae in a garden in Durban, Kwazulu Natal, Republic of South Africa.

Asexual propagation of the new cultivar was first accomplished by shoot division in July of 2010 in Durban, Kwazulu Natal, Republic of South Africa. Asexual propagation by shoot division has determined that the characteristics of the new cultivar are 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. These attributes in combination distinguish ‘Starlight’ as a distinct cultivar of Anthericum.

• • 1. ‘Starlight’ exhibits variegated foliage with light yellow-green and creamy-white midribs, and multiple longitudinal stripes throughout the darker green leaf blade.
  • 2. ‘Starlight’ exhibits light yellow-green inflorescence stalks.
  • 3. ‘Starlight’ exhibits golden yellow colored flower buds.
  • 4. ‘Starlight’ exhibits white flowers with yellow tips and bright yellow stamens.
  • 5. ‘Starlight’ exhibits non-viable seeds that are sterile; germination produces white leaves that quickly die.

The parent plant of ‘Starlight’ differs from ‘Starlight’ in having green foliage and green flowering stalks. ‘Starlight’ can be most closely compared to the cultivars ‘Agristripes’ (not patented) and ‘Variegata’ (not patented). ‘Agristripes’ is similar to ‘Starlight’ in having variegated foliage and in having a compact plant habit. ‘Agristripes’ differs from ‘Starlight’ in having green inflorescence stalks, green flower stalks, dark green midribs, and in producing viable seeds. ‘Variegata’ differs from ‘Starlight’ in having flower stalks that are green in color, in having foliage variegation with green centers and white margins, and in producing viable seeds.
