Jess, the Fritillaria is growing out front in the main flower bed and the Symplocarpus is growing in the backyard under a pine tree where it is always moist and mossy.
Alpha, really? I never really knew that was the term for generating heat. Yes I am thinking from Chem class [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img] An endothermic reaction takes in energy and an exothermic releases energy...would have that that would have applied to the Symplocarpus because of the bio chemical reaction between the starch to produce heat, therefore it should be exothermic.
