I introduced a new oxygenating plant in the spring and, amazingly, it has blossomed with beautiful single white flowers (shown in the first photo). A lovely surprise!
I bought an iris in the spring of 2010 and, although it grew strongly that year, it didn't flower. However, this year it has already produced a beautiful yellow flower (second photo) and a further bud as well (third photo).
The final photo shows the lovely overhanging plant that my son, Jamie (the pond's designer) recommended that I introduce. It helps make the pond more natural, and I intend planting more next year. The flowers are an extra bonus, adding more beauty!
