USPP20410P2 - Cistus plant named ‘Rencis’ - Google Patents

Abstract

A new cultivar of Cistus, ‘Rencis’, characterized by its variegated leaves that are retained throughout the year with leaves with dark grey-green centers surrounded by yellow to creamy white colored margins that may become tinted with orange in autumn, its compact plant habit, and its white flowers present in late spring to early May.

Description

Botanical classification: Cistus×corbariensis.

Variety denomination: ‘Rencis’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cistus×corbariensis and will be referred to hereafter by its cultivar name, ‘Rencis’. ‘Rencis’ is a new cultivar of evergreen shrub grown for use as a landscape plant.

The Inventor discovered ‘Rencis’ in his nursery in Gorron, France in July 1993. The new cultivar arose as a naturally occurring branch mutation of an unnamed plant of Cistus×corbariensis that was growing outdoors in a container in his nursery.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 1995 in Gorron, France. The cuttings were grown for a period of seven years in the Inventor's garden to test for stability prior to subsequent propagation. The characteristics of ‘Rencis’ 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 test garden in Gorron, France. These attributes in combination distinguish ‘Rencis’ as a unique cultivar of Cistus.

• • 1. ‘Rencis’ exhibits variegated foliage with leaves having dark grey-green centers surrounded by yellow to creamy white colored margins. The margins become tinted with orange in autumn.
  • 2. ‘Rencis’ exhibits foliage that is variegated throughout the year.
  • 3. ‘Rencis’ exhibits a compact plant habit.
  • 4. ‘Rencis’ exhibits white flowers in late spring to early summer.

‘Rencis’ differs from its parent plant, Cistus×corbariensis, in having variegated foliage, a more compact habit, and in producing less flowers. ‘Rencis’ can be compared to a cultivar of Cistus known by the Inventor to have variegated foliage; Cistus ‘Candy Stripe’ (unpatented). It is similar to ‘Rencis’ in having compact habit and foliage with yellow to gold margin, however, it differs from ‘Rencis’ in having margins narrow.
