Re: air space vs exploding cells was: Pulmonaria questions

Jennifer, which statement?  The air spaces or the exploding?  The
exploding was what Bobbie Brooks  posted that Tony Avent said was the
cause of the silver/white color in Pulmonaria leaves.   My totally
unbotanical understanding of this phenomena was that the silvering
was caused by air spaces in the leaf cells - which have no
chlorophyll, so no green color. Now, if that is so, why they are
silver colored, I don't know.  I could be out of my mind...frequently
am....maybe some botanist type on the list can clarify.
