Do you mean I should be suspicious of someone who grows deadly nightshade?

I wonder if the types of plants a person has at home (not the factory type) gives some clues as to their personality type.

> (My conclusions from what I've read about this:) Except for the fragrance of some plants, it would seem reasonable to conclude that houseplants have mainly a psychological effect, not a biologically significant effect. Also, an indoor environment in which plants thrive (well-regulated humidity, clean, free-flowing air, outside air exchange, etc.) is also an indoor environment in which people do better, and things like black mold and excessive airborne dust will not be thriving. We also like bright daylight (or the best indoor simulation of it we can put together), as do most plants. So thriving houseplants may be more of an indicator of good indoor air quality (and an attentive indoor gardener) than a cause of good air quality.
