Cyclamen, for example, imbibe moisture via the roots even in dormancy. Try 
lifting a cyclamen tuber in summer and leaving it on a shelf. It will soon get 
flabby.

Tulips pose another interesting example of how people misinterpret words. It's 
commonly said that tulips need to be dry in summer, and a fair number of people 
misinterpret this as meaning a sandy soil. Nothing could be further from the 
truth; tulips do best in a rather heavy clay-ish soil that goes dry in the 
summer. Put them in a lean, sandy soil and they won't thrive like they do in a 
heavier soil.
