Our mystery South London street tree has been identified thanks to a correspondent who was able to recognise a fine avenue of Hippophae salicifolia. Several others suggested sea buckthorn (Hippophae rhamnoides) which, as it turns out, was close but discounted due to size (tree rather than a bush), evergreen foliage and few berries. My own guess at a food plant of giraffes was wide of the mark…
The positive identification was verified by the Hippophae salicifolia page on Hillier Nurseries’ website featuring a picture of the exact same street tree I had been struggling to identify, apparently there is a 15m specimen to be found at Kew too.
The common moniker that has emerged for this tree is the very unsatisfactory ‘willow-leaved sea buckthorn’. This plant’s natural habitat is dry Himalayan river valleys hundreds of miles from the sea, so I detect botanical imperialism at work in a name relating to our familiar European coastal species more appropriately known as sea buckthorn.
In my opinion our tree needs a new name – Hippophae are sometimes called sandthorn or sallowthorn; our tree is certainly not sallow, so I am proposing willow-leaved sandthorn.
