Barberry seeds are seeds that can be grown with level 77 Farming. They are planted in bush patches, one seed per patch. Patches can be protected by paying a farmer 15 hammerstone hops. The seed grows in three hours and twenty minutes and yield 1600 experience points from checking the health, and 50 farming experience per harvest (you can only pick once per bush). You will also have a chance to gain Agility experience on a successful pick you will get intervals of experience. The amount of Agility experience you gain per "interval" depends on your Agility level. When harvesting fruit from a fully grown bush you will somersault over the bush to the opposite side, then eat the fruit immediately. No item is actually gained from harvesting a barberry bush.
