Black Mulberry

Morus nigra

Britain's silk industry failed on a species error and left the trees behind. We map 13 of them, in 10 cities.

In 1608 James I ordered mulberries planted across the country to feed silkworms, but silkworms eat white mulberry and mostly refuse black, and black was what went into the ground. Charlton House got one of them and it is still fruiting four centuries later. Christ's College in Cambridge planted another in 1608 or 1609, the year after John Milton was born. The oldest here is older than the scheme: Adam Winthrop planted the Groton mulberry in Suffolk around 1550, on the ground where his grandson grew up before leading the Puritan fleet to Massachusetts. Its trunk collapsed decades ago and the fallen wood rooted again, which is how old mulberries keep going. Breda's public library was designed around three of them rather than the other way round.
