Typical Watsonia meriana (less than 1 m high and never producing bulbils) has been reported only once, from heathland near Anglesea. The larger, bulbil-producing, Watsonia meriana 'Bulbillifera' (the Bulbil Watsonia) is the more common variant in Australia, and is a proclaimed noxious weed in most States of Australia. It is locally abundant as a weed of roadside, unimproved pasture and waste land. This sterile polyploid possibly originated as a sport introduced into cultivation; it has become a vigorous weed due to its exceptional capacity for vegetative reproduction.
