The Arc/Berries

Berries of the Arc is an activity in the Arc, for which players can find and breed berries of various types. Rumberries have a significant use outside trading as it's required in Tuai Leit's Own and is an ingredient for making Arc gumbo, but finding all berries (listed in the Arc Journal) is required for the final Arc unlock.

Eating a berry provides temporary stat boosts. All berries can be sold to Terri (fruit merchant), found in the gnome encampment in western Tuai Leit, or Sinuman (food merchant) on Cyclosis.

Players can sell berry seeds to Ani's Seed Store by the Sea Shore who can be found in the Gnome colony on Tuai Leit.

Harvesting from planter
Each bush is harvested separately in one action. The entire amount of berries and seeds are put into the player's inventory.

Cross-pollination
In order to obtain any berry besides rumberries and exuberries, players need to either find a seed in a rare Uncharted Isles chest or cross-breed them in the farming plot in central Tuai Leit.

Players can add two seeds to the patch to cross-pollinate and grow mature bushes. Harvesting when both plots in the patch are mature after approximately 42 hours rewards some new berries and seeds.

Unlike real seeds, that only produce pollen after flowering, berry seeds will cross-pollinate if they are planted next to each other - even before any growth shows. Therefore - always harvest one berry and immediately replant it before harvesting the second bush. This will ensure that each possible combination will produce a crossed seed.

If different seeds are planted next to each other, even if one is grown and the other just planted, harvesting the grown bush may yield a new cross-polinated seed along with the regular items.

Players do not require 86 Farming to plant or harvest from berry patches, only to obtain the rumberry/exuberry seeds initially.

Recommended order
The most efficient order to cross breed all seeds (excluding stoneberry, stormberry and their respective crosses) is as follows:

Then, finishing up with the stormberry and stoneberry crosses can be done this way:

The various seeds still need to be planted, as the journal tracks actual berries obtained, not their seeds.

Incompatibilities
These berry combinations yield no cross-pollination results:
