The medlar was already being cultivated about three thousand years ago in the Caspian Sea region of northern Iran. It was introduced to Greece around 700 BC, and to Rome about 200 BC. It was an important fruit plant during Roman and medieval times. By the 17th and 18th century, however, it had been superseded by other fruits, and is little cultivated today. M. germanica pomes are one of the few fruits that become edible in winter, making it an important tree for gardeners who wish to have fruit available all year round. M. germanica plants can be grafted on to the rootstock of another species, for example the pear, quince, or hawthorn, to improve their performance in different soils.
Mespilus germanica fruits are hard, acidic, and high in bitter tannins. They become edible after being softened, 'bletted', by frost, or naturally in storage given sufficient time. Once softening begins the skin rapidly takes a wrinkled texture and turns dark brown, and the inside reduces to the consistency and flavour reminiscent of apple sauce. This process can confuse those new to medlars, as a softened fruit looks as if it has spoiled.
A most famous reference to medlars, often bowdlerized until modern editions accepted it, appears in Shakespeare's Romeo and Juliet, when Mercutio laughs at Romeo's unrequited love for his mistress Rosaline (II, 1, 34-38):
Now will he sit under a medlar tree,
And wish his mistress were that kind of fruit
As maids call medlars, when they laugh alone.
O Romeo, that she were, O that she were
An open-arse and thou a pop'rin pear!
In the 16th and 17th centuries, medlars were bawdily called "open-arses" because of the shape of the fruits, inspiring boisterous or humorously indecent puns in many Elizabethan and Jacobean plays.
Take them as they come, I suppose.
