Zantedeschia aethiopica "green goddess"
Green goddess is an evergreen arum lilly. Although Zantedeschia are not proper arum's this is a common name given to them.
Green goddess produces trumpet shaped flowers from late winter into spring. Although in our experience in our climate it seems to flower sporadically throughout the year.
The flowers are an unusual mixture of green and white and tend to blend into the lush vibrant green foliage. The leaves become quite large on well established clumps.
Zantedeschia's are ideally suited for areas with ample moisture. Bogs and pond margins are perfect. Would also work in a grey water wetland.
Whilst ideally they do prefer wetter conditions the clump in our garden has been growing under a fully established coryline for years. During the summer the ground there is dry and hard as a rock and the green goddess survives.
Can be grown in full sun and quite deep shade. It's a very hardy plant and can be difficult to remove if no longer wanted.

Is zantedeschia green goddess easy to remove if i no longer want it?
Green goddess can be a pain to remove, because it holds so much water within it's foliage, its very hard to kill will a traditional herbicide using glyphosate.
The best way to remove it is to dig up the clumps as the smaller juvenile plants sprout you can then treat with a herbicide or pull them out. They will continue to pop up for 2-3 years so vigilance is the key to full removing them.
