What

Most of the main species of British tree are represented in the park, though it's a bit lacking in the hedgerow trees. There are privet hedges around the tennis & croquet lawns, a beech hedge around the cottages at the east end and some new holly bushes on Leamington Walk, but apart from some cute little parterres on the north side of Bruntsfield Links, there's not much else in the way of hedgerows.

There also hadn't been many conifers till recently, but from 2015 onwards, several attractive individuals have been planted, in particular the new pines and cedars.

Look out for these:
