Sarcococca plant named ‘Sarsid 2’

Abstract

A new cultivar of Sarcococca named ‘Sarsid 2’, characterized by large and broad, oblanceolate shaped leaves, its dwarf, consistent, and dense but spreading plant habit that is suitable as a groundcover, its vigorous growth habit, and its small highly fragrant flowers that emerge in mid winter.

Description

RELATED APPLICATIONS

This application is co-pending with a U.S. Plant Patent application for a cultivar discovered from similar parentage entitled Sarcococca Plant Named ‘Sarsid 1’. (U.S. Co-pending application 12/075,529).

Botanical classification: Sarcococca hookeriana var. humilis.

Variety denomination: ‘Sarsid 2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sarcococca hookeriana var. humilis. The new cultivar will be referred to hereafter by its cultivar name, ‘Sarsid 2’. ‘Sarsid 2’ is an evergreen shrub grown for use as a landscape plant.

The inventor discovered ‘Sarsid 2’ as a naturally occurring whole plant mutation in spring of 2002 in his nursery in Mission, British Columbia, Canada. ‘Sarsid 2’ was selected as a single unique plant after evaluation of 2,000 seedlings derived from seed sown in 1999 of unnamed plants of Sarcococca hookeriana var. humilis.

Asexual reproduction of the new cultivar was first accomplished by the inventor using stem cuttings in winter of 2002 in Mission, British Columbia, Canada. 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 a trial garden for five years in Mission, British Columbia, Canada. These attributes in combination distinguish ‘Sarsid 2’ as a unique cultivar of Sarcococca.

• • 1. ‘Sarsid 2’ exhibits large and broad oblanceolate shaped leaves.
  • 2. ‘Sarsid 2’ exhibits a dwarf, consistent and vigorous growth habit.
  • 3. ‘Sarsid 2’ exhibits a consistent plant habit; forms a dense clump but slowly spreading by rhizomes; suitable as a groundcover.
  • 4. ‘Sarsid 2’ produces racemes of small, nearly white, highly fragrant flowers in February in British Columbia, Canada.

‘Sarsid 2’ differs from its parent species Sarcococca hookeriana var. humilis, in having larger and broader leaves and in having a more consistent plant habit and a more consistent and vigorous growth habit. ‘Sarsid 2’ can be compared to ‘Sarsid 1’, another selection of the inventor. ‘Sarsid 1’ is similar to ‘Sarsid 2’ in growth and plant habit, however ‘Sarsid 1’ has narrower leaves. ‘Sarsid 2’ can be compared to Sarcococca hookeriana var. digna (not patented); var. digna it is a much larger plant as ‘Sarsid 2’ is a cultivar derived from the dwarf var. humilis and ‘Sarsid 2’ also has broader leaves.
