Key features include:
Tendency to talk to plants, having a large collection of indoor plants, and gardening books.
Also look for:
In their pockets, particularly of jackets or hoodies or even purses- you will likely find parts of plants like seed pods, loose seeds, bits of moss, sticks, or dried leaves. Pockets of plants is a key identifier of the local plant-person.
If you put your hand in your own jacket pocket, and get dirt under your nails, you know you're a botanist.
