Holly plant named ‘MAD-IC1’

Abstract

A new cultivar of Ilex crenata plant named MAD-IC1, that is characterized by its broad columnar-fastigiate habit, its exceptional strong branches that do not splay, its coriaceous lustrous dark green pest-resistant foliage, and its propensity to produce shiny black fruits if a suitable pollinator is in proximity.

Description

Genus and species: Ilex crenata.

Variety denomination: The new Ilex crenata claimed is of the cultivar denominated ‘MAD-IC1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ilex crenata and will be referred to hereafter by its cultivar name ‘MAD-IC1’. ‘MAD-IC1’ is a new cultivar of holly grown for use as a landscape and container ornamental plant.

The new cultivar of Ilex arose from a breeding program conducted by the inventor. ‘MAD-IC1’ originated as a seedling from seed derived from open-pollinated Ilex crenata ‘Sky Pencil’ (not patented). Male parentage is unknown. ‘MAD-IC1’ was selected as a single unique plant in 2007 from among the resultant seedlings.

Asexual propagation of the new cultivar was first accomplished by greenwood cuttings (semi-hardwood) in a nursery in Watkinsville, Ga. in 2008. Asexual propagation by semi-hardwood cuttings 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 observed repeatedly and represent the characteristics of the new cultivar. These attributes distinguish ‘MAD-IC1’ as a unique cultivar of Ilex.

• • 1. ‘MAD-IC1’ exhibits a broad columnar-fastigiate habit
  • 2. ‘MAD-IC1’ develops exceptionally strong branches that do not splay
  • 3. ‘MAD-IC1’ exhibits pest resistant, lustrous dark green, coriaceous leaves which do not discolor in winter

COMPARISON TO OTHER VARIETIES

• • 1. ‘MAD-IC1’ differs from ‘PIIIC-1’ (U.S. Plant Pat. No. 29,578) as ‘MAD-IC1’ is a female and produces shiny black fruit; and ‘PIIIG-1’ only produces male flowers
  • 2. ‘MAD-IC1’ is about twice as wide as ‘PIIIC-1’ at maturity
  • 3. ‘MAD-IC1’ develops stronger branches than ‘PIIIC-1’
  • 4. The branches of ‘MAD-IC1’ do not splay like those of its parent plant ‘Sky Pencil’
