White Eggplants - you might want to consider one of the egg shaped varieties. Some people say there is a taste difference - white eggplants being a bit milder and fruitier - personally I don't discriminate based on color and don't really see much of a difference in taste - so once you go black - sure you'll go back [and forth]. In the eggplant realm the whites are the minority, but a novel deviation.
1. Aretusa - 6- inch long Elongated pure white eggplant variety with a spineless calyx. High-yielding mild taste and texture. Begins producing early and continues producing so long as you continue harvesting. Uniform high gloss white coloration.
2. Aysberg Heirloom Eggplant. Hales from the Ukraine, a rarity sometimes hard to locate. I bought some seeds off ebay a few years ago and they turned out to be standard purple eggplant seeds repackaged. I am told the taste is superior, I started some plants this year and have my fingers crossed - I'll let ya know.
3. The absolute best of the full sized White Eggplants in my opinion is Casper Eggplant. It's taste is undeniably different, not just a subtle difference but 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.
4. Cloud 9 Eggplant is a prolific hybrid white eggplant. The fruits are between 5 and 8" long. Cloud 9 produces more prolifically and is easier to maintain than Casper, but the taste is not as good. It's still a good eggplant comparable in taste to most standard varieties.
