I forgot to describe the other fountain I setup. Originally, like I said, I was just going to have the one barrel so I had purchased a small fountain pump. Since I changed my idea I need to do something with this little fountain. One of the nurseries I visited in my search for ideas had spiderwort growing in shallow water (not over its crown). Since I had a Hawaiian Punch (purple) spiderwort and hadn't decided what to do with it I though this was a great idea. I ended up buying 3 more, bilberry ice (white and purple), snowcap (white), and JC Weguelin (china blue). I placed them (pots and all) in a wide shallow pot with the little pump and fountain the middle, filled in with drain gravel and topped the pots with pea gravel. It has made nice little fountain with a very pleasant sound. Terry E. WA.
