The rose marks 175 years of the Met

The red climbing flower also celebrates 175 years of the Metropolitan Police.

The force said strategic placing of the thorny plant helps deter intruders and make it more difficult for burglars to get into homes.

To mark the first year of the Met, when there were 1,000 officers wearing top hats, its stand at the show will be in an 1829 Regency town house garden.

It will also feature crime prevention typical of the time - such as spear-headed iron railings - together with a period planting scheme.

A contemporary urban garden makes up the second part of the stand showing what a secure garden should like.

Met Commissioner Sir John Stevens said: "Naming a rose after New Scotland Yard is a wonderful way to mark this historic year for the Metropolitan Police Service.

"In true Met style the rose also has a crime reduction function and the Chelsea Flower Show is the ideal platform to illustrate garden security in action."

A donation from the sale of each New Scotland Yard rose will be made to the Safer London Foundation, a charity that supports crime reduction work.
