Most reproduction appears to occur via the bulbuls.
All of the bulbuls produced by a wild garlic plant are genetically identical to each other. Several theories predicted that she would find better germination and growth in arrays of genetically variable individuals than arrays of genetically identical individuals since plants in genetically variable arrays may differ in their resource requirements and susceptibilities to pathogens. Instead, Ronsheim found better germination and growth in genetically identical arrays than in the genetically variable groups in both field and the greenhouse experiments. One potential explanation suggests that the bulbuls produce germination enhancing chemicals and that these chemicals are clone specific. In other words individuals surrounded by members of their own clone might receive higher doses of such chemicals than those surrounded by members of other clones.
