I found this information about peppers:
"Q. Are ornamental varieties of chiles poisonous?
A. There are absolutely no varieties of peppers that are poisonous, all capsicum species are edible. Some of the ornamental varieties just don't taste very good, while others are extremely hot or pungent which may lead to this misconception. However there is an ornamental plant called a False Jerusalem Cherry, botanical name, Solanum Capsicastrum, this plant is poisonous and is not intended for consumption, it is not a chile plant only a relative.
