Medlar: The Medieval Fruit That Must Rot to Be Eaten
The medlar is so strange you must let it half-rot ("blet") before eating. The story of this medieval European staple, almost extinct in modern times.
The medlar (Mespilus germanica) is one of medieval Europe's most distinctive fruits โ and almost forgotten today. The brown apple-shaped fruit must be left to "blet" (partially rot) for 1-3 weeks after harvest before it becomes edible, transforming the rock-hard tannic flesh into a sweet date-like pulp.
Origin and history
Native to southwest Asia and southeastern Europe. Cultivated by the Greeks and Romans; widely planted across medieval Europe for fresh eating and preserves. Fell out of fashion in the 1800s as softer fruits became more widely available year-round.
Where medlars grow today
Wild-naturalized across temperate Europe. Small commercial production in the Caucasus, Turkey, and parts of Europe. Mostly home-garden in the modern era.
How to grow medlar
USDA Zones 5-9. Small spreading tree (4-6m). Tolerates a range of soils. Self-fertile. Often grafted onto quince rootstock. First fruit in 3-4 years.
Bottom line
A heritage fruit worth preserving. Plant one and you have a quirky beautiful tree producing date-flavored autumn fruit that no supermarket will ever sell.
