Sticky question?

Recommended Posts

No don't worry this isn't a 'my plant has no dew' question.:happy:

Is the dew of a Drosera purely exuded from the plant?

I've been thinking about this for some time and in my hunting I have yet to find a definitive answer. I know some of the composition of the dew and it is mostly water and the plant has a ready supply of that. Is it all from the glands of the plant or is the dew hygroscopic? I know there are many polysaccharides that are hydroscopic and the dew does contain them but there is a cocktail of other things in there so I'm not sure how that would affect water uptake from the air.


Any ideas?
