Easter Egg Plant
Solanum sp. (melongena esculentum) Hybrid

Bright Fruits Look Exactly Like Easter Eggs!
Amaze the neighborhood children with a summer visit from the Easter Bunny!

Who says Mother Nature hasn't got a sense of humor? You really won't believe Easter Eggplant until you grow it and watch the fruit develop for yourself--it begins white, looking for all the world like a bunch of hen's eggs, and then matures to deep pastel cream, yellow, orange, and even green! Just 12 inches high, the petite plants can sport a dozen "eggs" in a season!

No trouble to grow in any sunny, well-drained spot, Easter Eggplant is actually a member of the Potato family, with wide, lush green foliage protecting the fruit. It is an uncommon delight for the summer garden, and a constant source of wonder to children and the young at heart! Pkt is 25 seeds.
