Do you have any custom CSS on site or adblockers on your browser that might be blocking them?

I always use the custom CSS code to put them in the top corner, else I would miss all of them.

.floating_item { border:2px solid blueviolet; position:absolute !important; left:5px !important; top:5px !important; }

I double-checked and can confirm that flowers are going out. It is random so you might be having an unlucky day with the RNG. I think the suggestion to play Slots or Scratchcards is a good one, since more page loads means more chances to spawn them, and those games reload the page a lot. Hope you see some soon :)
