Plant Breeder's Rights are the Breeder's legal protection over the propagation of a plant.
Although the name of a Cultivar is correctly defined with the addition of a Cultivar name, another epithet is often used to market a plant when the original Cultivar name is considered unsuitable. This is called a Trade Designation name. Both the Cultivar name (in single quotes) and Trade Designation name (shown here in Small Capitals) should always be shown together on labels etc..
The following is a list of those garden plants (excluding fruit & vegetables) which have Plant Breeder's Rights in the UK and in the EU (which of course includes the UK) The indicated year is when the current protection runs out. A listing does not imply it is available. [Rights Ended] with the plant name struck through indicates that rights have been terminated.
PBRs which are applied for but not yet granted, are NOT included in this listing.

I am particularly interested in tracking down the trade designation names for some of the plants which only have what you might call 'trade cultivar' names.
