Rose plant named ‘Emily Carr’

Abstract

A new and distinct variety of rose, distinguished by its deep red flowers, disease resistance and cold tolerance.

Description

Latin name of the genus and species of the plant claimed: Rosa sp.

Variety denomination: ‘Emily Carr’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose named ‘Emily Carr’. The new rose ‘Emily Carr’ resulted from a hybridization programme and is a selection from a series of cross by manual pollination. The series can be described as follows:

[(Lammert's selection×Morden Cardinette)×Morden Cardinette]×Cuthbert Grant

The cultivar was created in Morden, Manitoba in 1982, Canada, and selection subsequently occurred at another location in Quebec, Canada in 1998-1999.

The ‘Emily Carr’ rose plant variety of the present invention: a) is resistant to mildew, b) almost continuous flowering, with deep red flowers, c) the flowers are semi-double, d) the plant is a large shrub with an upright growth habit, and d) shows cold tolerance.

Asexual reproduction of this new variety shows that the foregoing and other characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations. The instant cultivar was asexually reproduced by softwood cutting in Morden, Manitoba, Canada. Cutting size can be variable but new shoots (soft-wood) taken 3-5 nodes in length root well under intermittent mist, common in the industry. Root hormone (IBA) can speed root development.

The colours of an illustration of this type may vary with lighting and other conditions under which conditions and, therefore, colour characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED DESCRIPTION

The original variety and progeny have been observed growing in a cultivated area in Quebec, Canada. Certain characteristics of this variety, such as growth and colour, may change with changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). Colour descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Colour designations are made with reference to the Royal Horticultural Society (R.H.S.) Colour Chart. All colour characteristics were determined using the 1986 version of the Royal Horticultural Society (R.H.S.) colour charts and measured characteristics were based on ten plan measurements. It should be understood that the colours may vary, depending on factors such as growing and lighting conditions.

The comparative tests and trials for ‘Emily Carr’ were conducted in Morden, Manitoba. The plants were placed in groups of 3 with a plant spacing of 3 feet and row spacing of 7 feet. Evaluations were made over 7 years. The plants used in the assessment of the characteristics were planted in 1996 (long beds) and 1991 (NTA) and had reached mature stature when assessed in 2005 and again on Jun. 30, 2008 and on Jul. 11, 2008.

‘Emily Carr’ can be distinguished from its parents by the following:

• • The female parent, ‘Cardinette’ (unpatented) derived selection is a less hardy selection. ‘Emily Carr’ is more vigorous;
  • Compared to its male parent, ‘Cuthbert Grant’ (unpatented), ‘Emily Carr’ is redder in color, is more up-right and has slightly smaller flowers.

The ‘Emily Carr’ rose was compared to the ‘Champlain’ (unpatented) variety, referred to as the “reference variety.” For comparison, several physical characteristics of the rose variety ‘Champlain’ (unpatented) are compared in Chart 1.
