FINALLY my Water Hyacinth have bloomed. It is not why I purchase and put in these annual pond floaters, but it is a nice bonus to have lilac, scented flowers in the dog days of DC.
I think I actually enjoy my water garden more than any other aspect of my yard. I am captivated by the creatures it attracts. I love the beauty of the water lilies. I enjoy watching my little fishies gobble up more than their weight in insects. Most of all I love the LOW maintenance aspect of it. After the first two years of set-up and getting the right water balance -- all I do now is a spring clean-up/set-up and a fall prep for the winter. That is it. Just a few hours of work twice a year. No other part of my garden gives such reward with such little effort.
BTW, there is a myth I keep encountering and would like to bust: Water Gardens Do NOT attract or create mosquitos. (However, Bog gardens are a different story...) Here is a link to a good story on the subject: http://watergarden.com/wgn/2006/JA/JA.htm. Scroll down to Randall Tate's article.
