Hydrangea Macrophylla Blaumeise – Blue Tit. Translated from German Blaumeise means Blue Tit - a small European bird. It is a fantastic addition to the TELLER series developed in Switzerland, comprising lace-cap hydrangeas with beautiful colours. Blaumeise is supposed to be the most reliable blue flowering variety. From midsummer it produces large lace cap flowerheads with brilliant cobalt blue fertile flowers encircled by pale turquoise blue sterile flowers.
