Cercis canadensis L.

Redbud leaves, Cercis canadensis, fresh spring leaves at their births, at the end of the cycle, no leaf is untouched by another organisim, be it insect, arthropod, virus, fungus, or bacteria and eventually drops. A particularly lovely member of the pea family.

Ah....the redbud a lovely native leguminous north american small tree. Widely planted, awesome pollinator pollen and nectar food source...and...very interestingly, it has clear seed pods until mid summer which allows investigators to look at rates of pollination....could be used as a sentinel and a great citizen science project.
