Juan Bueno flowers are an important source of nectar for the Juan Fernández firecrown (Sephanoides fernandensis), a hummingbird that is also only found on the Juan Fernández Islands but is almost extinct today. The hummingbird, in turn, may be an important pollinator for the plant.^{[verification needed]}
