Re: rose serum

@tarynx24  There is an open bug report on plants not producing at the science lab.  It is located here: [OPEN] [GTW] Plants at science lab don't produce harvestables - Answer HQ (ea.com)

You'll need to grow the roses at home and bring them with you, leastwise, that's what I do.  It would be good if you would take a minute and click "me too" on that thread.  You can also post your experience, if you would like to do so.
