I believe this game has some deeper mechanics as you mentioned in comments, but I can't figure things out in the game itself :/ Especially the green button - I tried to proceed all the hints but am stuck with green button doing nothing (or nothing I am noticing actually :D)

First, I forgot to mention that you have to stand pretty much right in front of the button and the two kiosks inside for them to register. With that being said, this is the progression I intended:
This arrangement should give you the blue seeds. Once again, don't forget to stand directly in front of the green button!
Once a seed / species has been "unlocked", so to speak, you can sell 15 of them at a time at the dollar sign on the right -- in other words, you're guaranteed to be able to sell only things you can produce. Note that the items you can sell changes every time you go in and out of the building (this was my take on infinity - that demand for goods is always changing - but the implementation was awful).
Once you have 1500 - 1700 dollars, click on the blue/pink kiosk on the left to see this
Click on the number to "unlock" the next species of flowers. The clues are meant to tell you what to plant. 
This will give you access to a new type of seed -- note its resemblance to the first "clue". Repeat the process for the second clue, and the game is effectively finished.I wish I could've done better with "show and don't tell". In any case, I hope you find this helpful. And thanks for hosting the gamejam!
