I am happy that I bought mine as plants. These darn things (eggplants) grow slowly so they would have to be started in January in the middle of winter! No way for me. They have a great selection of all sorts of eggplants at the nurseries here. I will just buy them each year.
Unless you need a lot of plants because you do market, I can't see why you need to bother starting them as seeds, just buy afew plants.
I have a neighbor and friend that lives next door and she is impatiently waiting for eggplant, zucchini and tomatoes. So both of us are impatient.
