Solanum melongena
Dark purple skin. (78 days) Open pollinated.

Kent Whealy brought this elongated slightly tapered dark purple eggplant back from Ukraine in 1993. 2' plants set 2½x7" slender 12 oz fruits in clusters. Firm flesh has good texture and entirely lacks bitterness. Because of its mild flavor and good cold-climate adaptation, Diamond is growing in popularity. Our trialer in Maine had an average yield of 4 lb per plant.

Additional Information

Eggplant

  • 200-300 seeds/g.
  • Days to maturity are from transplant date.

Culture: Growing eggplant can be a challenge in the north. Start indoors in early spring. Minimum germination temperature is 60°, optimal range 75–90°. Transplant after all danger of frost. They resent wind, will not set fruit in cold or very hot temperatures or in drought. We recommend irrigation and using row covers and IRT mulch. Our selections are the most reliable producers we’ve found, yet some seasons even our skilled trialers get only sparse production of ripe fruits.

Colorado Potato Beetle (CPB)
Cultural controls: Rotation, control solanaceous weeds such as horse nettle, rapid flaming, suction devices, hand-picking if beetle pressure is low, mulch before adults arrive.
Material controls: Surround, Spinosad
