My eggplant are pretty jungle-like also, although I've learned that staking them helps immensely. The fairy tale plants have slightly smaller leaves than the Ping Tung, and that makes it much easier to find the fruit. I have 3 eggplant and 3 peppers in an Earthbox. That is the recommended planting, and they've done well that way the past few years (although the foliage is pretty dense). Only change I made this year was to grow one less eggplant and one more pepper.
