I like Millionaire. They're mild. But to be honest, unless an eggplant's bitter I really can't tell much difference in taste between eggplants. Maybe it's just my palette but to me an eggplant is an eggplant.
This plant has survived an army worm attack earlier and looks a bit worse for the wear but is still producing. I picked the two in the photo and now there are five more, each about 2" long and a lot more flowers. New foliage being set too. First frost will most likely be around Nov 10th.
