'Duke of Cambridge' rose Description

My HMF:

HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

Notes:

This rose is growing at the San Jose Heritage Rose Garden. They list the breeder as Laffay.
Mike Lowe gives this rose a date of 1848. In their 2002 Catalogue, Pépinières Loubert say the breeder is Margottin and the date 1867.

The POM study in Sweden classed 'Duc de Cambridge' as a Bourbon (see References); it is therefore possible that 'Duc de Cambridge' in gardens and commerce is not the damask by Laffay, but rather the HP by Margottin.
In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This is one of the outstanding varieties which showed a 0% to 5% infection rate. The data was taken on well-established roses.

Adolphus Frederick, Duke of Cambridge, seventh son of George III of England. Born 24 February 1774 at Buckingham Palace. Died at Cambridge House 8 July 1850. Buried in St. George's Chapel, Windsor Castle.
