I used rye. It comes up in 7-9 days. Its about 6 inches tall already. I'v never heard of dutch clover. The rye dies out after the 1st year. Its cheap less than a dollar a pound. I might try and look for the clover also thanks for the tip.

The people who say I can't do it can just sit the @^#% down and watch me. Friends call me Rusto I also subscribe to pond boss mag. http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=504716#Post504716
