Rivers' Early Prolific plum trees
Prunus domestica An attractive English plum, sometimes known as Early Rivers, or, mistakenly, as a "river plum". Rivers' Early Prolific is, as the name suggests, an early and heavy-cropping plum. Rated by the Victorian fruit enthusiast Hogg as "a great bearer, and very hardy, rarely ever missing a crop".
It is dual-purpose, but arguably better for culinary purposes. (For dessert purposes, Opal is probably better).
Rivers' Early Prolific is easy to grow and crops reliably.

How to grow
Rivers' Early Prolific is unusual for a plum tree in that it grows with a slightly "pendulous" habit - somewhat reminscent of an upright weeping willow. The trunk will eventually reach the normal proportions but the branches and twigs always stay disproportionately thin.
Cropping potential is often greater than the branches can bear, so thinning of the fruit and/or branch supports may be necessary.
Like some of its offspring (e.g. Czar) Rivers' Early Prolific can also tolerate shade.
Somewhat counter-intuitively, whilst Rivers's Early Prolific crops heavily, it is not a vigorous tree, and tends to be small or average size.

History
Rivers' Early Prolific was raised by the famous Thomas Rivers nursery in Hertfordshire, UK, in the 1830s. It was developed from an early-season French plum variety called Precoce de Tours.
It was grown commercially in the UK for a period, and has also been used to breed a number of other popular plum varieties, including Czar.
