The Maltese Cross is best seen during early June when the array of silver, blue and white plants are in full bloom. The cross is made up of Sisyrinchium, Iris, Campanula and numerous varities of Delphinium with a large Scottish Thistle in the centre.
Behind the Maltese Cross is what is referred to as the Rainbow Border. Planted in blocks of colour ranging from whites, yellows, reds, pinks and blues, it is home to plants such as Acanthus, Ballota, Tamarix and a Colletia.
