It will also seed - mainly the 'wild' form.
There are 'cultivated' versions which have pink, red, yellow tones of flowers, but the 'wild' form has orange to light orange colored flowers.
Up here in the Dandenongs it is another environmental weed and on some roadsides (off the main roads) and park/bushland areas there are whole huge patches of the stuff.
As you said Fred, shade loving/tolerant plant.
Fortunately not quite as pervasive as the arum lily family (zaccanthias spelling?)
