Sunflowers
Sunflowers is a building material gathered by flock ducks.
Gathering
Pick sunflowers from a Sunflower Patch using upgraded gloves. Direct a duck to the resource, or let village residents choose their own work. A depleted resource regenerates after two minutes.
Building
Spend Sunflowers on buildings and upgrades at the 
Upgrade Well. The building menu lists the amounts you need.
