You can change the name of the plant you're currently growing. Give it a super cool name by following the steps below:

1. Tap Handbook (2nd button from the left on the bottom)
2. Find your plant's information (at the bottom of the bar graph)
3. Tap the name field to change it
4. Tap the v in the top left to complete

＊ Reminder:
It's only possible to change the name of the plant you're currently growing. Plants already in the greenhouse cannot be changed or renamed!
