“Aesculus hippocastanum (Horse Chestnut) is one of the most well-known and loved of all trees. Very attractive in late spring with its white, tinged yellow then pink, candle like flowers, followed by burnished conkers in their spiky casings. It originates from the borders of Greece and Albania and was introduced to Ireland and Britain in the early 1600s. It does wonderfully well in parks and open spaces.”
