i'd stay away from Dutch white. if it is the same stuff I am thinking of, it is a native clover that grows very low and doesn't produce high yeilds. if you are going to plant something go with Ladino clover & maybe some red. Ladino can be a bit pricey ($4-5/#). I'm not sure how that compares with Imperial. However, you don't need many #/acre. I would say no more than 5#/ac. (maybe a bit more). We generally recommend 1-3 for pasture planting with grass. there are a lot of seeds in a pound of Ladino (871,000) and they go a long way.
