At this time of year, the streets and gardens of St Andrews are full of extraordinary cherry blossom. I have just learned the reason.
In 1975, Zenya Hamada was given permission to create a replica of the Old Course (I needn’t specify which sport!) in Japan. In gratitude he gave the city of St Andrews a thousand Japanese flowering cherries. These were distributed to owners of private gardens, and also planted in the streets. There is a particularly fine row very near my house, in Tom Morris Drive (appropriately!)
The cherries were the featured plant of the month in May 2010; you can still access the web page and read about them there.
