Only 5% of seeds have viable embryos, possibly due to lack of pollinating insects in winter. Seeds germinate after drying for several years and then being exposed to rainwater seeped through charcoal created by a brush fire. The nitrogen dioxide in the charcoal triggers germination. Manzanita burns quickly and intensely so it must be situated at least 30' from any structure. Appears best when growing near an area where water collects or runs by. Evergreen. Full or part shade. Better appearance in part shade.
