It grows best in areas where annual daytime temperatures are within the range 30 - 42°c, but can tolerate 10 - 47°c. When dormant, the plant can survive temperatures down to about -4°c, but young growth can be severely damaged at -1°c. It prefers a mean annual rainfall in the range 1,200 - 2,300mm, but tolerates 750 - 2,800mm.

Succeeds in full sun and also in light shade. Plants are tolerant of a range of soil types, so long as they are well drained, but grow best on deep, rich, acid soils that are rich in organic matter. It grows on rather dry to occasionally swampy locations on various, often rocky, gravelly or loamy, well drained, preferable slightly acid soil.
