1. A cartridge for an e-vaping device, the cartridge comprising:
a housing extending in a longitudinal direction;
a plurality of reservoirs positioned within the housing, the plurality of reservoirs extending in the longitudinal direction and configured to hold different pre-vapor formulations;
a dispensing interface coupled to the plurality of reservoirs, the dispensing interface including a plurality of separate wicks coupled together, the plurality of separate wicks each including absorbent material; and
a heater coupled to the dispensing interface,
wherein the dispensing interface includes
a trunk that is a portion of the dispensing interface that includes coupled portions of the plurality of separate wicks and is surrounded by the heater,
a plurality of separate roots that include non-coupled portions of the plurality of separate wicks extending away from the trunk, the plurality of separate roots extending in the longitudinal direction into separate, respective reservoirs of the plurality of reservoirs, such that the dispensing interface is configured to draw the different pre-vapor formulations from the plurality of reservoirs into the trunk via the plurality of separate roots, and
at least one constrictor coupled to at least one root of the plurality of separate roots, the at least one constrictor being configured to adjustably control a rate of transport at which the at least one root draws at least one pre-vapor formulation based on adjustably constricting a diameter of at least a portion of the at least one root to adjust a porosity of the portion of the at least one root,
wherein the heater is configured to vaporize the different pre-vapor formulations simultaneously.
