As the Sunflower Patch does not produce special resources upon motivation, it has a low priority in the motivation order and will only get motivated randomly with the regular buildings after all special buildings that produce forge points, goods, guild power, medals, or blueprints have been motivated. Use a Self-Aid Kit if you want to make sure your Sunflower Patch is protected from plunderers if you cannot collect on time and you have regular plunderers coming along.
Every 24 hours the Sunflower Patch will produce the following resources. Base resources will always be produced. Bonus resources are determined by how many other unique Harvest Farm Set buildings it is connected to.
