A batch of giant redwood seeds arrived at the Veitch nursery in Exeter in 1855, and the Smythe family bought quite a few of them, apparently. Many of the sequoia around Bristol date from around then, including the lovely tree in Paradise Bottom in Leigh Woods, which would then have been Leigh Court's arboretum.
