Flowers from March to July from buds formed the previous season. Moist sphagnum surrounding leatherleaf shoots, roots, and rhizomes causes vigorous vegetative growth. Sphagnum grows on leatherleaf stems and branches but does not inhibit growth. Ice breakage can result in rapid expansion of colonies. It also establishes well in windfall areas.
Seeds germinate on sphagnum or sedge mats.
