African violets
African violets are oftentimes associated with grandmothers (because grandmothers make a hobby out of collecting all the African violets on the planet, for no particular reason).
What’s extremely interesting about them is that they’re not high pollen producers. Just like knickknacks, they catch dust due to the super velvety texture of their leaves.
That’s one of the main reasons why people who suffer from dust allergies should definitely avoid these beautiful, warm, and fuzzy plants, which are unfortunately not as easy to clean as more glossy-leaved types.
I personally love African violets, but if they trigger allergies too, I will have to admire them from a safe distance.
Chrysanthemums
People who constantly sneeze at chrysanthemums should definitely keep in mind that the plant is related to ragweed. It seems that its pollen, along with other allergens that are also present on the flowers and leaves, could ultimately cause hay fever symptoms, which are often associated with its more raggedy cousin.
Also, chrysanthemum foliage might raise rashes on the skin of those who constantly handle the plant. For some indoor gardeners, chrysanthemums are definitely not a good choice!
