May has to be one of the best months of the year for garden beauty. The leaves on the trees are fresh and lush green, and many shrubs are covered in blossom, including the native Hawthorn. Grass lawns are in great condition and alpine plants in rockeries are full of colour. The Horse Chestnut tree, best known for it's conkers in autumn, has fantastic candles of quite exotic pink/white flowers this month. Most people overlook this, but if you live near a conker tree, go and take a look and you'll see them amongst the distinctive leaves.
