Sometimes they just form flowers in clusters. It's normal, not a male/female difference. Usually eggplants will form a single flower, or a cluster of up to 8, depending on the variety.

I'm growing Rosa Bianca Eggplant and it is same as you describe. Single large blossoms on a strong stem, and some clusters of three smaller blossoms on small stems away from the main stalk. Now I thought the larger blossoms were female, and that the cluster of smaller blossoms were male. And I thought the male flowers were necessary to pollinate the females. The bees are visiting the eggplants now so I don't worry, but early on I hand pollinated some of the blossoms, or at least I thought I did. Anyway, the larger blossoms I thought I pollinated have medium size eggplants now. I did notice something else interesting. When I brushed the female plants, I could see a little puff of what looked like very fine powder. (I'm not making this up...)

Hope someone can tell me if what I did was unnecessary. Do eggplants not require male/female blossoms for pollination?

Eggplants are like tomatoes self-fertile. Flowers have both male and female parts. Bees when plentiful will work the flowers, but the plants don't need them.

Farmerdilla, thanks for the info. I feel a little silly now, but apparently I didn't harm the early blossoms.

Greenthumbsj, It was not my intention to hijack this thread. I apologize for jumping in.

opal52, no worries. I learned more because of your input. I am all for more input.
