Answer: Crimson clover will ultimately grow to a thick stand in summer, though it does take a while to get started. If this is the only plant grown on the site, you should seed it at about 1/2 lb/1000 sq ft. It doesn't like acidic soil, so it may not like itunder the oaks, since their fallen leaves increase soil acidity. You can check your soil pH with a home test kit, or have the extension service test it for you. Peaceful Valley Farm Supply offers a North American Partial Shade Wildflower mix (1/4 lb. is around $10) that might be a better choice. Also, Vinca minor (periwinkle) grows well in partial shade and covers the ground quickly while providing beautiful blooms, though I haven't yet found a source of seed. Burpee offers plants, though! Enjoy!
