French Improved Prune Tree

Description

French Improved Prune Tree is a classic European plum for gardeners who want fruit that moves effortlessly from the tree to the pantry. Medium, elongated plums ripen deep purple around firm golden flesh with concentrated sweetness and enough structure for drying into traditional prunes. The fruit is also delicious fresh and performs beautifully in preserves, pastries, sauces, and baked desserts. Its firm texture and high sugar content help flavors intensify rather than disappear during cooking or drying. Delicate white spring blossoms bring orchard beauty before the dependable late-summer crop develops. For home preservers, bakers, and anyone who appreciates an old-fashioned European plum, French Improved offers remarkable versatility: a productive tree whose harvest can be eaten immediately, stored in jars, or dried for enjoyment long after plum season ends.
French Improved grows semi-dwarf on Citation rootstock and is suited to USDA zones 5–9, with a confirmed 800-hour chill requirement. In suitable climates, harvest generally spans August through September. Plant in full sun, prune for airflow, and allow fruit to develop full sugar before processing.
French Improved is self-fruitful and can bear alone. Another compatible European plum may improve set; consider Italian Plum or Blue Damson.
