Eggplant Height Varies Depending on the Variety
The most common eggplant (Solonum melongena) for home gardeners produces deep purple, plump fruit. Other eggplant varieties include Japanese eggplant, white eggplant and miniature eggplants. The height of mature eggplant bushes depends on the eggplant cultivar you choose for your garden. Compact varieties can grow only 2 feet, while others reach 4-feet tall.
