I guess I've bought the hype. I planted Imperial clover last spring and had very good luck with it with the exception of the portion of my plot that was underwater for a week. It has come back strong now for the second year and I reseeded the portion of my plot that was drowned last spring just a few weeks ago. It has germinated and is coming along nicely.

If I were planting acres I might be concerned about the money, but I invested a ton of time preping my plot so the extra money spent is insurance to me that I will not have "spend my time" repreping and resseding my plot.
