It may depend on the variety, but you may need a male plant. The one you have is a female, it will bear the fruit. The male plant's flowers grow on a stem that sticks out from the trunk of the plant. The female's flowers are on the trunk.
I have one in a pot, for now, that supposedly does not need a pollinator. I got it on eBay and it is not the usual type we see here. I'm glad I did not leave it out this week with the 25 degree temps we had. The two self-seeded plants that grew up in the compost heap were severely burned.
