Dr. Campbell Davidson Recognized

 

The following article is reprinted from The Landscape Trades Publication published in September 2004:

Dr Campbell Davidson was selected to receive the Keith Laver Award from the Canadian Ornamental Plant Foundation (COPF).  This award, named after the renowned rose breeder, recognizes outstanding contributions to relations between the ornamental horticulture industry and government.

Dr Davidson served primarily as a research scientist at Agri-Food Canada's Morden Research Centre since 1984.  Earlier this year, he was named Director of Genetic Resources with the International Science Program in Ottawa.  Dr Davidson is well known in the nursery sector for his many new plant introductions and volunteering on numerous boards and committees.

We congratulate Dr Davidson on this prestigious award and wish him continued success.

 

SHADE-TOLERANT ROSES

Shrubs and climbers are among the most vigorous of all our rose families, often growing to seek their own sun rather than requiring that the sun come to them.  With such large varieties, the consideration is usually “where will it fit in,” rather than “where should I put it to get sufficient sun.” However, there are many modern shrub types and families that are relatively low growing and still should considered for areas of at least partial sun.

 

 

 

David Austin’s English Roses are a very popular group of roses with a variety of plant types and habits.  Research indicates, ‘Abraham Darby’, ‘Ambridge Rose’, ‘English Garden’, ‘Glamis Castle’ and ‘Golden Celebration’ are a few that are touted as being shade-tolerant, although several more could probably be added to this list.

 

            Polyanthas are a class by themselves, consisting primarily of medium to low-growing floriferous bushes, and most would likely do best in the foreground with adequate sun.  Three that apparently have good tolerance for shade are ‘The Fairy’, ‘Pinkie’ and ‘White Pet’.

 

            Most of the “classic” shrub families, the bybrid musks, rugosas and kordesii, tend to consist of large plants that can take little/no direct sun.  Some recommendations here include:

 

Hybrid Musks:           ‘Ballerina’, ‘Buff Beauty’, ‘Cornelia’, ‘Eva’, ‘Felicia’

 

Hybrid Rugosas:        ‘Blanc Double de Coubert’, ‘F.J. Grootendorst’, ‘Hansa’, ‘Thérèse Bugnet’

 

Hybrid Kordesii:        ‘Dortmund’, (plus most other of this class).

 

Of those “non-classic” varieties classified simply as “shrubs,” those reviewed as being good for shady areas include ‘Bayse’s Purple Rose’, ‘Carefree Beauty’, ‘Carefree Delight’, ‘Flutterbye’ and ‘Marjorie Fair’.

Finally, climbers and hybrid wichuranas (formerly ramblers) making the shade-tolerant list include ‘Altissimo’, ‘Blaze’, ‘Coral Dawn’, ‘Fourth of July’ and ‘Albéric Barbier’.

 

            These lists of shade-tolerant varieties are in no way exhaustive; many more varieties could be added, and the best way to find out if a
