Hi Marie. In my experience, paper whites generally only flower once a year. I believe you can βforceβ then by putting them in a paper sack in your fridge for a while, but Iβve not tried it. Good luck!
I would plant her in the yard do not cut back her leaves she needs them to capture energy for the bulb so she can come back next year. You will have a nice surprise next spring. β€οΈπ±π€ͺππ
