One of the earliest plums. Very good as a dessert plum when ripe. Otherwise a good plum for cooking and making jam. Plums round oval dark blue with a heavy bloom and golden yellow flesh. Heavy cropping, living up to its name. Raised by Thomas Rivers at his nursery in Hertfordshire about 1820.
Though often refered to as a culinary plum it is small in size. Usually culinary and dual purpose plums are of a larger size. Much grown in Plum growing areas in the later 1800’s & early 1900’s when it probably gained a reputation for its cooking and preserving qualities. However it is very nice to eat fresh with a stone that is quite ‘free’ when ripe.
It has several synonyms including Early Rivers, Rivers Early Prolific. It is not self fertile requiring a pollinator(s) in the vicinity. Rootstock: St Julien A
