Goji Berry is a limited edition 7-Eleven seed in FarmVille, available only through purchasing an eligible in-store item from the retail chain and redeeming a code found on it. Due to a glitch, several people were able to purchase the seed the morning of May 17, 2010. It was released for anyone to purchase for another 18 days between January 20 and February 6, 2011.
The seeds cost 15 coins to plant, and can be harvested every sixteen hours for 126 coins. They also award 2 XP per plot.
Upon its general release, the number of plantings needed for Mastery was also increased from 80-160-240-480 to 300-600-900-1800.
FarmTrivia: Pound for pound, the Goji Berry has more Vitamin C than an orange.
