A culinary plum but very good as a dessert when ripe. Upright growth with frost resistance. One of the most prolific croppers and self fertile. This plum owes its name to the visit of the Tsar of Russia in 1874. Raised by prolific plant breeder and nurseryman Thomas Rivers from a cross between Early Prolific and less well known Prince Englebert.
Dark purple skinned fruits with yellow green flesh. Shape round / oval and of medium size with a moderately wide and deep suture (a single grove that runs from top to bottom of plums). Stone semi free.
