It has small, shiny, very dark green leaves and tiny, vanilla-scented flowers in winter.
It is the hardiest of the azaras, withstanding temperatures down to −15 °C (5 °F), but in cooler temperate regions requires some protection from cold winds.
[1] The specific epithet microphylla comes from the Greek micro ("small") and phyllos ("leaf").
