Other info. - This striking
species is found in the lower 1/3 of Missouri basically southeast of a
line from Vernon County to Pike County. The plant grows in acidic soils
and doesn't transplant well which is probably why it is not seen much in
cultivation. The fruits of this species are edible but are tough and
hard to eat.
