Seeds come from the shop. You equip one and plant it on an open plot. The shop does not keep a frozen list: restock notices in one session named guyabano, ilang-ilang, and catmon. If a crop is missing, check again after the next restock. The length of that timer is not published.
Crops that were actually read off the shop, plus mango from the BAHAYKUBO code, are catalogued under seeds. Kalamansi is the tutorial crop. Pinya kept producing after the first pick in that session, so leave a pineapple planted instead of deleting it. Other crops were not checked for a second harvest.
Do not copy a shop percentage into a plan unless you can see what the label measures. A session mentioned a percent next to saging and another next to langka, and it was not clear if those were stock odds or profit. The reliable rule is still the tutorial: bigger and rarer fruit sells for more, and the sell prompt shows the pesos.
Mango is the one seed with a code source: BAHAYKUBO pays 3 Mango Seeds and 500 Pesos. Plant those on open plots the same way as a shop seed.
Kamagong, kasoy, duhat, and duhat gubat were separate listings. Duhat and duhat gubat are not the same row. A spoken shop walk also sounded like cocoa, coffee, or basil, but those words were not clear enough to add as crops.
