I have one thriving allspice plant in my southern exposure window. Will it ever get berries or does it need a second allspice plant nearby for
The allspice plant (Pimenta dioica) is dioecious, meaning that it produces male and female flowers on different plants. So to get fruit you would need two plants of different sexes. Even then, you may not get fruit as container-grown allspice plants rarely produce fruits. Best to enjoy the fragrant leaves!
