Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: North American plant that inhibits mold and mildew growth
Answered by: Nan Hampton

QUESTION:

Hi! There, I just wanted to know is there a north American plant that inhibits or eradicates mold and mildew growth, in the home. Also do they make a CFL (the new energy efficient spiral) type light bulbs for plant growth that really work. Thank you

ANSWER:

Sorry, but Mr. Smarty Plants hasn't been able to find any plant in North America (or elsewhere, for that matter) that inhibits or eradicates the growth of mold/mildew. We did learn that there is a leachate from compost of alfalfa and sunflower stalks that controls black mold (Aspergillus niger) in onion sets, but I think what you are looking for is a plant that has some airborne component that inhibits or eradicates the growth of mold and mildew on surfaces (such as walls) in the home. So far as I know, it doesn't exist. Your best bet is to reduce the moisture in your home and provide more air circulation. Here is some advice from the University of Florida Extension Service about preventing and removing mildew.
