I've heard that O. nutans is invasive in some European gardens, but I've 
been growing it here in Oregon for about 15 years (received from a seed 
exchange under the misnomer O. arcuatum) and it has not spread at all. It 
may be better-behaved in a summer-dry climate. On the other hand, I also 
grow O. umbellatum, naturalized in rough grass and not watered in summer, 
and it has never appeared anywhere else either.
