All the plants in the Click & Grow selection have a definite life cycle - due to the limited space and possible amount of nutrients per each soil pod, no plant will be able to reproduce indefinitely. Some plants can be repotted if a longer life cycle is desired. What is more, a large part of edible plants are annual, meaning they are able to yield one harvest. While some herbs do last longer than salad greens, for instance, each pod will reach the end of its life cycle sooner or later, as the soil pod can only contain so many nutrients and space for the roots to grow.
Some general insight on the average life cycles is illustrated below:

A rule of thumb is that once a plant has been fully harvested, it will not be able to regrow and it should be replaced with a new pod. Happy growing!
