for what it is worth the technical def. of a "
weed" is an unwannted plant. therefore it depends who you ask if a plant is a "
weed" the Chinese Tallow Tree is a commonly planted ornimental in California, the same plant is a noxious
weed in Fla. Pampas Grass is a common ornamental in Fla. and is a noxious
weed in Ca. so it seems a "
weed" is in the eye of the beholder...
