You have to clear quests before you can unlock plant upgrades. You can click on the buttons in the Greenhouse but it won't do anything until it's green which you do by clearing quests. In Twin Sunflowers' case, it just sends you to a boxing arena which meant there was a quest related to it, but there was nothing I could do.

No need to be hostile. Oops, forgot that the last Sunflower upgrade has a quest that is not in the Normal version... Why don't you play that arena? Because you need to be a certain level to participate in it, and I hadn't been at that level at the time I had posted this thread.

Also, almost all of the quests aren't in Normal Mode. The first few ones are, but everything (as far as I know, the game doesn't really tell you when you've beaten one of the quests but I stopped unlocking stuff from Normal Mode) after the first world must be unlocked by doing stuff like getting your plants up to a certain level, having a 4-star plant, getting enough Puzzle Pieces to raise it to a certain tier, having a certain tier of equipment, etc.

Almost nothing is unlocked in normal mode after Qin Shi Huang Mausoleum.
