The user has planted at least one plant on his map.
Main success scenario:
When viewing the map on such a date, the plants with an active blooming or harvesting period at that time will be marked on the map.
Alternative scenario:
Optionally, this can be disabled in the users' preferences.
Error scenario:
The app incorrectly displays a plant as having an active blooming or harvesting period or does not display it for a plant that should have one.
In this case the user should reload the layer to let the system recalculate the conditions for displaying active blooming or harvesting periods.
Postcondition:
The user always sees what personal benefits he gets from the plants on the map.
