Orchids. You don’t have to worry about orchids if you get hay fever or allergic to flowers. Although they are not pollen-free (they have sticky pollen), it’s very unlikely for the pollen to become airborne.
The plants that need to be looking out for are the ones where the pollen can be transferred by the wind.

Can orchids cause headaches ?

Orchid pollen packet
Orchid pollen, which is very small and sticky, is all contained in a “pollen packet” that is intended to get stuck on a bug or another pollinator in order to be transported to another orchid plant. It doesn’t float in the air like most pollen from other flowers that can be seriously irritating for allergy sufferers. This packet doesn’t travel through the air and into people’s noses so allergies are not an issue with orchids.
