The absolute best of the full sized White Eggplants in my opinion is Casper Eggplant. A French Heirloom, it's taste is a scrumptious variation. If you've ever read anything about these eggplants, you'll see them being described as tasting like mushrooms, and that is perhaps the best way to describe them. They actually do taste like Mushrooms - certainly don't taste like chicken.
They are a reliable, but slow producer of 5-6" long glossy white eggplants. They prefer a cooler climate in comparison to most other varieties. Extended periods of hot weather will sometimes stunt their growth and hamper fruit development. Under optimal conditions they can bear fruit right up to the first hard frost.
Post Harvest - They do not store very well and should be eaten within a day or two of harvest. Stored in the refrigerator their skin will sometimes oxidize and turn brown.
Maturity at 70-80 days from transplant.
Germination from seed Aprox. 14 days. Casper Eggplant seeds do not germinate in cool soil. Soil Temperature should be maintained around 80 degrees F

Eggplant grows best in a well-drained sandy loam or loam soil, fairly high in organic matter. Start early indoors in peat pots or cell packs
All eggplant varieties are highly susceptible to Flea Beetles attack particularly early in the season. Aphids also attack these plants and come later in the season. Varieties of Aphids that attack eggplants are generally either a light blue-green or amber, sometimes black.
The outdoor environment can be very harsh for a transplant. So, harden the transplants before planting outdoors to increase their survival rate. Place them outdoors in their original containers where they will receive direct sunlight and some wind for a few hours each day for a week, possibly more.. Gradually lengthen the amount of time outside each day. Move the plants inside at night.
