keep waiting. I usually soak scarified seeds in water until the embryo sends out a shoot. Then i transplant (be careful, they are tender!). Can take weeks to make that obscene little thing emerge in water [change water regularly]. Then I put them in a peat pot and seal it in a zip bag. When it pops able the soil, open the zip bag a little every couple of days. I leave the peat pot in the zip bag until I pot it up to harden it off. Whites are more tedious than yellows/orange, at least for me.
