Where it grows wild

Grows along the Red River valley from Hekou to Shuangbai, likely on slopes in open woodland and scrub; substrate detail is not published in the sources reached.

The single georeferenced record is at about 1770 m near Gejiu, but much of the range is in the lower, hotter valley.
