This year I planted three varieties of eggplant: Casper, Rosita, and Listada de Gandia, from Seed Savers Exchange. The plants are beautiful, with thick, lush foliage, and we had good hot growing weather here in Minnesota in July. However, the plants have hardly flowered at all! When there have been flowers, they are small and inconspicuous, and no fruit comes from them. I have grown eggplant before, and have never seen this. I can understand if this happened to one variety, but with three different varieties I expected at least one of them to produce! Does anyone have any idea why this might be happening? Thanks!
