Parts of the Cecropia such as the stipules, the spathes, and the main veins of the lamina have red-coloring substances. The concentration of the substances varies, even within species, and some parts can be green, bluish, pale pink, dark red, dark purple, and even blackish. The color may fade with age, and can be deposited equally or in patterns such as longitudinal stripes.
