You don¡¯t have to be a dendrophile to enjoy BBC2¡¯s Meetings with Remarkable Trees series; history comes into it, too. This week, two special trees get their ten-minutes¡¯ worth: on Friday (9.50; 10.20 in Wales), the Duke of Wellington¡¯s American-derived Wellingtonia redwood, a testament to the era of the ¡°great white plant hunters going around the world¡± (in the words of forester Tony Russell) is the focus. On Monday (9.50) we can take a look at ¡°Milton¡¯s mulberry¡±, planted in the garden of Christ¡¯s College, Cambridge, in the year of Milton¡¯s birth, as part of James I¡¯s failed project to encourage silkworm cultivation. ?
