The eggplant is a delicate, tropical perennial plant often cultivated as a tender or half-hardy annual in temperate climates. The stem is often spiny. ... Some common cultivars have fruit that is egg-shaped, glossy, and purple with white flesh and a spongy, "meaty" texture.
Always wash your produce when you get home!
Whole eggplant will last better and longer out of the refrigerator but in a cool place — 50 degrees is ideal. On the countertop, eggplant should keep for about 3 days. If storing cut eggplant, wrap in plastic and place in the least cool section of the refrigerator.
