Black? Do you mean the seed coat? I went through three batches of seeds before I could get them to sprout, and that was after I sanded deeply enough that I could see a clearly defined white 'spot'. Once they start germination, you should see the seed coat start to crack, like in my pic below. The shoot coming out won't be black, though. I posted this pic in a different thread. Note how big and deep my sanding was. I had no luck if I sanded on the side of the seed, only at the end. Good luck!
