Where it grows wild

It grows on the ground in shaded, moist forest. Its huge range and wide elevation span suggest it tolerates a broad range of conditions.

It is recorded from 200 to 2,200 m. Plants from high sites will prefer cooler nights than lowland ones, so the targets below aim at the middle of the range.
