I have been busy gathering information about my plant, specifically regarding dormancy requirements.
I came across the following about P. emarginata: "The Tropical Homophyllous species have the simplest requirements. They have no dormancy, and only have one type of leaf-form"
And P. ehlersiae: "Perhaps 95% of these tropical heterophyllous species come from Mexico. They generally flower twice per year and exhibit different leaf types in summer and winter."
So a cross between a none dormant and dormant species, will it go into dormancy? So far it is not showing any sign of going dormant or leaf change. They are growing outside and receiving less light because of the seasonal change.
